  1. Tropical Storm Marco Discussion Number 16 NWS National Hurricane Center Miami FL AL142020 400 AM CDT Mon Aug 24 2020 Marco is clearly weakening tonight. Data from an Air Force Reserve Hurricane Hunter mission showed that flight-level and SFMR had decreased along with a substantial rise in central pressure. In addition, GOES-16 1-min satellite data show the surface center well displaced from the deep convection, and it appears that Marco is decoupling from its mid-level circulation to the northeast. The initial wind speed is set to 50 kt, and that could be generous. Some large changes have been required on this forecast. Considering the shear is only forecast to increase, there is no significant chance that Marco re-intensifies to a hurricane, and the hurricane warnings have been replaced with tropical storm warnings. Furthermore, now that the storm is losing vertical coherence, the intensity forecast has been decreased as well, and is fairly consistent with the model consensus and almost every model. Marco has turned northwestward this morning at about 9 kt. The storm should gradually turn westward as it approaches southeastern Louisiana due to the shallower cyclone feeling the low-level ridge. Marco will likely dissipate in a couple of days near the Texas/Louisiana border due to continued strong shear. Guidance has come into better agreement on the track going slightly inland or just brushing the Louisiana coast, and the track has been nudged southward on this advisory. It should be noted that the heaviest rain and strongest winds will likely be northeast of the center, so users should not focus on the exact track of the cyclone. Key Messages: 1. Gusty winds, dangerous storm surge, and heavy rainfall are expected from Marco along portions of the Gulf Coast beginning later today. Interests in these areas should follow any advice given by local government officials. 2. Tropical Storm Laura could bring additional storm surge, rainfall, and wind impacts to portions of the U.S. Gulf Coast by the middle of the week. This could result in a prolonged period of hazardous weather for areas that may also be affected by Marco. Interests there should monitor the progress of Marco and Laura and updates to the forecast during the next few days.

DISCUSSION AND OUTLOOK ---------------------- At 400 AM CDT (0900 UTC), the center of Tropical Storm Marco was located near latitude 27.6 North, longitude 88.2 West. Marco is moving toward the northwest near 10 mph (17 km/h). Marco is forecast to approach the coast of Louisiana this afternoon, and then turn westward and move very close to the coast of Louisiana through Tuesday night. Data from the Hurricane Hunter plane indicate that maximum sustained winds have decreased to near 60 mph (95 km/h) with higher gusts. Further weakening is expected, and Marco is forecast to become a tropical depression late on Tuesday and dissipate on Wednesday. Tropical-storm-force winds extend outward up to 105 miles (165 km), primarily northeast of the center. The estimated minimum central pressure is 1003 mb (29.62 inches).

  5. Tropical Storm Marco Discussion Number 15 NWS National Hurricane Center Miami FL AL142020 1000 PM CDT Sun Aug 23 2020 Marco is feeling the effect of strong southwesterly shear. The center, as identified by an Air Force Reserve Hurricane Hunter aircraft, is displaced to the southwest edge of the convective canopy. That said, Marco has not quite fully decoupled yet and has moved well right of the previous forecast. Data from the plane indicates that Marco has weakened; the highest flight-level winds were only 58 kt with unflagged SFMR winds just above 50 kt. Marco's intensity has been lowered slightly to 60 kt, but this is probably generous. The intensity guidance remains maddeningly inconsistent. The most recent runs of the HWRF and HMON show that there is still a chance that Marco could reach the Gulf Coast as a hurricane, despite the shear. While this seems unlikely given the current structure of the cyclone, it also seems slightly premature to rule it out entirely. After all, the shear lessened enough to allow Marco to briefly strengthen after it was strongly sheared for a time last night. The rest of the guidance shows Marco weakening further as it approaches the coast, and this seems like a more likely solution. The NHC forecast just holds Marco at 60 kt for the next 24 h, but its certainly possible it could already be weaker than that. Rapid weakening is likely by 36 h if it hasn't happened sooner and Marco is forecast to become a remnant low by early Wednesday. Marco's track is tied entirely to its intensity and structure. Once Marco becomes fully decoupled it will slow and turn westward. It is not out of the question that this could happen before Marco reaches the coast and the system never makes landfall. However, as long as the strong southwesterly upper-level flow contributes to the steering, Marco will continue to move more northward to north-northwestward. Due to the recent northward movement of Marco's center, the NHC track forecast has been adjusted in that direction, but it is blended to the previous forecast by about 36 h and onward. Confidence in this forecast unfortunately remains low since the model spread remains usually high. It is worth noting that Marco is a small tropical cyclone. The large area of Tropical Storm and Hurricane watches and warnings along the northern Gulf Coast is a reflection of the unusually high uncertainty in the forecast, and it is unlikely that all of those regions will experience tropical-storm-force winds or life-threatening storm surge associated with Marco. However, impacts will likely occur in some portions of the watch/warning area beginning on Monday, and heavy rain is likely across most of the region during the next couple of days. Changes to the watches and warnings are likely on Monday and users should consult products from their local weather forecast office for more information about potential hazards in their area. Key Messages: 1. Strong winds, life-threatening storm surge, and heavy rainfall are expected from Marco along portions of the Gulf Coast beginning on Monday. Interests in these areas should follow any advice given by local government officials. 2. Tropical Storm Laura could bring additional storm surge, rainfall, and wind impacts to portions of the U.S. Gulf Coast by the middle of the week. This could result in a prolonged period of hazardous weather for areas that may also be affected by Marco. Interests there should monitor the progress of Marco and Laura and updates to the forecast during the next few days.

A Hurricane Watch means that hurricane conditions are possible within the watch area. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. For storm information specific to your area in the United States, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. For storm information specific to your area outside of the United States, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1000 PM CDT (0300 UTC), the center of Tropical Storm Marco was located by an Air Force Reserve Hurricane Hunter plane near latitude 26.8 North, longitude 87.6 West. Marco is moving toward the north-northwest near 12 mph (19 km/h). A continued north-northwestward motion is possible tonight, but a turn toward the northwest is expected by Monday morning. Marco is forecast to approach the coast of Louisiana by Monday afternoon, and then turn westward and move near or over the coast through Tuesday. Data from the Hurricane Hunter plane indicate that maximum sustained winds have decreased to near 70 mph (110 km/h) with higher gusts. Fluctuations in intensity are possible during the next 24 hours, but Marco is forecast to weaken rapidly by early Tuesday. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure based on data from the reconnaissance aircraft is 1000 mb (29.53 inches).

  8. Tropical Storm Marco Discussion Number 7 NWS National Hurricane Center Miami FL AL142020 1100 PM EDT Fri Aug 21 2020 An Air Force Reserve Hurricane Hunter aircraft has investigated the system over the northwest Caribbean during the past few hours. The plane reported a number of unflagged SFMR winds between 35 and 40 kt and max flight level winds of 41 kt. A blend of these data supports an intensity of 35 kt, and therefore, this system has been designated as Tropical Storm Marco. Deep convection has increased near and to the east of Marco's center during the past few hours. Although there still isn't much evidence of inner-core banding, the data from the plane does indicate that the center of Marco has become better defined since the afternoon and that the minimum pressure has dropped. Unfortunately the intensity forecast has not become any clearer and confidence in that aspect of the forecast is quite low. Marco is embedded within an environment that could support a fast rate of strengthening. However, recent microwave data does not indicate that the system has developed an inner-core, and only gradual strengthening is likely until it does. The intensity guidance spread is quite high, with the GFS and ECMWF global models both showing little further strengthening, while the HMON regional model rapidly makes Marco a hurricane before it reaches the northeast tip of the Yucatan peninsula. That possibility can not be ruled out, but a majority of the intensity guidance favors the weaker solution of the global models. Even with the HMON outlier included, the NHC intensity forecast is above the model consensus. Once Marco moves over the central Gulf of Mexico, a rapid increase in wind shear associated with an upper-level trough should limit the potential for further strengthening, and weakening is still anticipated before Marco nears the northern Gulf Coast, as shown in the previous official forecast. Confidence in the track forecast is also lower than normal, as the models spread remains quite high. Only small adjustments were made to the NHC forecast which heavily favors the GFS and ECMWF solutions on the left side of the track guidance. It is worth noting that the NHC track forecast is near middle of the GFS and ECMWF ensembles. Marco is currently forecast to move northwestward toward a weakness in the subtropical ridge over the central Gulf of Mexico for the next day or two, before the ridge builds and turns the tropical cyclone farther west. Near the end of the period, Marco's track and intensity could be also influenced by Tropical Storm Laura which is also forecast to be over the Gulf of Mexico, however the details of that interaction are highly uncertain at this time. Given the high uncertainty in the forecast, larger than normal changes could be required to future advisories. Key Messages: 1. Marco is forecast to strengthen over the northwestern Caribbean Sea through Saturday as it approaches the northeast coast of the Yucatan Peninsula. A Hurricane Watch and a Tropical Storm Warning are in effect for portions of that region. 2. The system is expected to move into the south-central Gulf of Mexico as a tropical storm on Sunday. Although some strengthening is anticipated on Sunday, weakening is forecast as the system approaches the northwestern Gulf coast on Tuesday. It is still too soon to know exactly the location and magnitude of impacts the system will produce along the central or northwestern Gulf Coast, and interests in that area should continue monitoring the progress of this system over the next few days.

DISCUSSION AND OUTLOOK ---------------------- At 1100 PM EDT (0300 UTC), the center of Tropical Storm Marco was located near latitude 18.7 North, longitude 84.9 West. Marco is moving toward the north-northwest near 13 mph (20 km/h). A slightly slower northwestward motion is expected for the next day or so, followed by an increase in forward speed by early next week. On the forecast track, the center of Marco will approach the east coast of the Yucatan Peninsula of Mexico on Saturday. The center will then cross the northeastern part of the Yucatan Peninsula Saturday night and move over the central Gulf of Mexico toward the northwestern Gulf on Sunday and Monday. Maximum sustained winds have increased to near 40 mph (65 km/h) with higher gusts. Additional strengthening is forecast during the next couple of days as the system approaches the Yucatan peninsula and Marco could be near hurricane strength when it moves over the central Gulf of Mexico on Sunday. Tropical-storm-force winds extend outward up to 90 miles (150 km) from the center. The estimated minimum central pressure is 1003 mb (29.62 inches) based on reports from the Hurricane Hunter plane. HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected to first reach the eastern Yucatan coast within the warning area by Saturday afternoon and will spread northward and westward within the warning area Saturday night, making outside preparations difficult or dangerous. Hurricane conditions are also possible within the hurricane watch area by late Saturday. RAINFALL: Marco is expected to produce the following rainfall accumulations through Sunday: Eastern portions of the Mexican states of Quintana Roo and Yucatan: 3 to 6 inches, isolated maximum totals of 10 inches. This rainfall may result in areas of flash flooding. Northeast Nicaragua and the Cayman Islands: 1 to 2 inches. NEXT ADVISORY ------------- Next intermediate advisory at 200 AM EDT. Next complete advisory at 500 AM EDT. $$ Forecaster Zelinsky

  11. down to 20 percent in the 8pm TWO Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 PM EDT Fri Aug 21 2020 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Storm Laura, located near the northern Leeward Islands, and on Tropical Depression Fourteen, located over the northwestern Caribbean Sea. 1. Disorganized showers and thunderstorms located between the west coast of Africa and the Cabo Verde Islands are associated with a broad area of low pressure and tropical wave. This disturbance is expected to move westward across the Cabo Verde Islands on Saturday and it will likely produce gusty winds and locally heavy rainfall there. Some slow development of this wave is possible during the next couple of days while it moves across the eastern tropical Atlantic before environmental conditions become less favorable for development. * Formation chance through 48 hours...low...20 percent. * Formation chance through 5 days...low...20 percent.

  12. Tropical Depression Fourteen Discussion Number 3 NWS National Hurricane Center Miami FL AL142020 1100 PM EDT Thu Aug 20 2020 The overall convective pattern has improved somewhat since the previous advisory, with a band of deep convection having developed near and just south of the low-level center. A pronounced mid-level circulation has been rotating westward to the north of the center of the broader low-level circulation, which has likely prevented the cyclone from becoming a tropical storm by now, especially given the very impressive outflow pattern. However, NOAA buoy 42057 to the north of the center recently reported a sustained wind of 29 kt at 4 meters elevation, which equals about a 32-kt 10-meter wind speed, which means that the cyclone isn't far from becoming a tropical storm. The intensity is being maintained at 30 kt until convection becomes more persistent. The center has been reforming a little farther north and has also slowed down, with the initial motion now being west-northwestward or 285/12 kt. The slower and farther north initial position has required a slight northward shift in the forecast track for the next 24 hours and, as a result, the center of the cyclone is no longer expected to make landfall very far inland over Honduras or Nicaragua, if it makes landfall at all. By 36 hours, the new NHC forecast track shifts back closer to the previous advisory track due to a strong mid-level ridge extending westward across Florida and into the eastern and central Gulf of Mexico. That feature is expected to keep the cyclone moving in a general northwestward direction on days 2-5, resulting in landfall over the northeastern Yucatan Peninsula on Saturday, and be approaching the northwestern Gulf coast by the middle of next week. The official forecast track lies along the southern edge of the guidance envelope, close to the middle of the simple consensus models and a little south of the NOAA-HCCA corrected model. Due to the northward shift in the new forecast track, the center and inner-core wind field of the cyclone will not be disrupted as much as previously expected, which has significant implications in the intensity forecast. The depression is now expected to reach hurricane strength just before it makes landfall on the east side of the Yucatan Peninsula in about 48 hours. Weakening is forecast in 60 hours while the cyclone moves across northeastern Yucatan, followed by gradual re-strengthening thereafter. Ocean temperatures along the path of the cyclone are forecast to be 30.0-30.5 deg C and the vertical shear is expected to remain low at less than 10 kt through 96 hours. Those conditions coupled with the impressive outflow pattern should allow for at least typical strengthening. By 120 hours, the GFS- and ECMWF-based SHIPS models show the vertical wind shear increasing sharply from the southwest to 20-25 kt, which would normally induce weakening. However, it appears that those models are incorporating some strong jetstream winds of 60-70 kt well to the northwest of the center of the cyclone, which has resulted in high bias in the shear output. Therefore, the cyclone is forecast to be near hurricane strength when it approaches the Texas coast in 120 hours. The new intensity forecast is similar to but a little higher then the previous advisory due to less land interaction than previously expected, and is is a blend of the Decay-SHIPS and LGEM models, which are at the upper-end of the guidance envelope. Key Messages: 1. Tropical Depression Fourteen is expected to strengthen over the northwestern Caribbean Sea through Saturday, and is likely to produce tropical-storm-force winds and heavy rainfall over portions of the coasts of Nicaragua and Honduras, including the Bay Islands, beginning tonight through Friday. The system is expected be near or at hurricane strength when it reaches the Yucatan Peninsula of Mexico late Saturday where a Hurricane Watch and a Tropical Storm Warning are in effect. 2. The system is expected to move into the south-central Gulf of Mexico as a tropical storm on Sunday. Some strengthening is anticipated while it moves northwestward over the western Gulf of Mexico early next week, but it is too soon to know exactly how strong it will get or the location and magnitude of impacts it will produce along the central or northwestern Gulf Coast. Interests in that area should continue monitoring the progress of this system over the next few days.

  16. Tropical Depression Fourteen Discussion Number 2 NWS National Hurricane Center Miami FL AL142020 500 PM EDT Thu Aug 20 2020 An Air Force Reserve Hurricane Hunter aircraft investigating the system found an area of lighter winds--likely where the center would be--farther south than previous estimates. The highest flight-level wind measured by the aircraft was 30 kt at an altitude of 2500 feet, and although there were some SFMR measurements over 40 kt, these looked coincident with some heavy rain rates and thus are probably not reliable. Therefore, the initial intensity remains 30 kt. Structurally, the depression has a large cloud envelope with sporadic convective cells located in loose bands. The updated initial position derived from the aircraft data indicates that the current motion is still westward, or 270/16 kt. This southward adjustment really only affected the first 36 hours or so of the forecast, with NHC's official track forecast being shifted southward during that period. This ends up taking the cyclone's center over extreme northern Nicaragua and northeastern Honduras in 12-24 hours. After 36 hours, model guidance remains in good agreement that the system should turn northwestward due to a deep-layer trough over the Gulf of Mexico. The new set of model guidance has not shifted much from the previous cycle, and the NHC track forecast is very close to the morning forecast despite the initial position adjustment, with perhaps a slight eastward shift on days 4 and 5. In general, the NHC forecast is closest to the GFS and HCCA model solutions. The depression's farther-south position makes the intensity forecast more complicated with potentially more land interaction with parts of Central America. Slight strengthening to tropical storm strength is expected before the center reaches Honduras and Nicaragua, with little change thereafter until the center re-emerges over the Gulf of Honduras. Low shear and warm sea surface temperatures should then support further intensification up until it reaches the Yucatan Peninsula. Since there is significant uncertainty in how land interaction will affect the cyclone's intensity, the forecast intensity has been flat-lined between day 2 and day 4, with the understanding that the the winds could increase or decrease from the value shown. Vertical shear is expected to increase by day 5, and some weakening is shown at that time. Key Messages: 1. Tropical Depression Fourteen is expected to strengthen over the northwestern Caribbean Sea through Saturday, and is likely to produce tropical-storm-force winds and heavy rainfall over portions of the coasts of Nicaragua and Honduras, including the Bay Islands, beginning tonight through Friday. The system could be near or at hurricane strength when it reaches the Yucatan Peninsula of Mexico late Saturday, and watches could be required for a portion of that area tonight. 2. The system is expected to move into the south-central Gulf of Mexico as a tropical storm on Sunday. Some strengthening is anticipated while it moves northwestward over the western Gulf of Mexico early next week, but it is too soon to know exactly how strong it will get or the location and magnitude of impacts it will produce along the central or northwestern Gulf Coast. Interests in that area should continue monitoring the progress of this system over the next few days.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Honduras/Nicaragua border westward to Punta Castilla Honduras * Bay Islands of Honduras * Puerto Cabezas Nicaragua northward to the Honduras/Nicaragua border A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within the next 12 hours. Additional watches or warnings, including for the Yucatan Peninsula of Mexico, may be required later this evening or tonight. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 500 PM EDT (2100 UTC), the center of Tropical Depression Fourteen was located near latitude 14.3 North, longitude 81.0 West. The depression is moving toward the west near 18 mph (30 km/h), and this general motion is expected to continue through tonight. A turn toward the west-northwest and northwest with a decrease in forward speed is forecast on Friday, with a general northwest motion continuing through at least Sunday. On the forecast track, the center of the system will move near or over extreme northern Nicaragua and northeastern Honduras, including the Bay Islands, on Friday and approach the east coast of the Yucatan Peninsula of Mexico on Saturday. The center is then expected to cross the Yucatan Peninsula Saturday night and move into the south-central Gulf of Mexico on Sunday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Strengthening is forecast during the next couple of days, and the depression is expected to become a tropical storm tonight. The system could be near or at hurricane strength when it reaches the Yucatan Peninsula of Mexico late Saturday. The estimated minimum central pressure is 1007 mb (29.74 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected to first reach the coast within the warning area by tonight, making outside preparations difficult or dangerous. These conditions will spread westward along the coast of Honduras within the warning area on Friday. RAINFALL: The depression is expected to produce the following rainfall accumulations through Sunday: Eastern portions of the Mexican states of Quintana Roo and Yucatan: 3 to 6 inches, isolated maximum totals of 10 inches. This rainfall may result in areas of flash flooding. Honduras: 2 to 4 inches. Jamaica and northern Nicaragua: 1 to 2 inches. NEXT ADVISORY ------------- Next intermediate advisory at 800 PM EDT.
