Subtropical Storm Theta Discussion Number 2 NWS National Hurricane Center Miami FL AL302020 900 AM GMT Tue Nov 10 2020 Theta has generally changed little during the past several hours. The cyclone has some characteristics of a tropical cyclone, including a central dense overcast and a relatively small radius of maximum wind. However, the storm is still entangled with an upper-level trough, and based on all of these factors, Theta is being maintained as a subtropical storm. The initial wind speed remains 45 kt, which is at the high end of the satellite intensity estimates. The storm is moving due eastward at about 10 kt. The track forecast reasoning seems fairly straightforward. A trough to the north of the subtropical storm is expected to lift out, and Theta should be steered eastward to east-northeastward during the next several days on the north side of a mid-level ridge. This motion should take the cyclone across the subtropical eastern Atlantic throughout the forecast period. The models are in fairly good agreement, and the NHC track forecast lies near the various consensus aids. Theta should transition to a tropical storm later today as it separates from the upper-level trough. Little change in intensity is expected during the next several days due to mixed environmental conditions. Although Theta will be tracking over progressively cooler SSTs and within moderate wind shear conditions, the air mass is expected to remain unstable, which should be supportive of deep convection. The NHC intensity forecast is similar to the previous one and lies near the high end of the model guidance.

Tropical Storm Eta Discussion Number 40 NWS National Hurricane Center Miami FL AL292020 300 AM CST Tue Nov 10 2020 There hasn't been a lot of change to the cloud pattern of Eta overnight, with the center apparently located on the northwestern side of a small central dense overcast. Scatterometer data from earlier indicated 35-40 kt winds, and with the typical undersampling from that instrument, along with consensus 45-kt estimates from TAFB/SAB, so Eta's initial wind speed is kept at 45 kt. A NOAA Hurricane Hunter aircraft should be in the storm this morning. Eta is forecast to be in a low-to-moderate shear environment over warm SSTs for the next couple of days. Gradual strengthening is expected through early Thursday, with the main restrictive factor being nearby dry air. After that time, increasing shear and drier mid-level air are likely to cause Eta to weaken. The rate of this weakening is pretty uncertain, and a lot depends on how much Eta can re-intensify over the next couple of days. The new forecast is similar to the previous one, which is quite close to the consensus guidance. The storm has basically become stationary overnight. Eta should drift to north today due to steering flow changes with a nearby upper-level low losing influence while ridging east of Florida builds southward. A slow northward track is then anticipated for a couple of days over the east-central Gulf of Mexico in this flow pattern. Beyond that time, model guidance is in rather poor agreement, ranging from a stronger system moving faster to the northeast due to broad troughing over the south-central United States, to a weaker tropical cyclone getting caught under a narrow ridge over the Gulf of Mexico and turning west-southwestward. Since the new forecast expects Eta to be weakening, the NHC forecast will be west of the consensus and west of the previous track. I have little confidence in the long-range track forecast due to its seeming dependence on the intensity, and the wide spread in the guidance. Key Messages: 1. Heavy rainfall from Eta will continue across western Cuba and South Florida today and tonight. Additional flash and urban flooding, especially across previously inundated areas, will be possible in South Florida. Flash and urban flooding will also be possible for western Cuba. 2. Eta could approach the Florida Gulf Coast later this week as a tropical storm, and possibly bring impacts from rain, wind, and storm surge. Interests in this area should continue to monitor the progress of Eta and updates to the forecast this week.

The storm is moving toward the east near 15 mph (24 km/h), and a general east-northeast motion is expected to continue during the next two to three days. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Some slight strengthening is possible during the next 12 to 24 hours followed by little change in strength through Thursday. Winds of 40 mph extend outward up to 115 miles (185 km) from the center. The estimated minimum central pressure is 1000 mb (29.53 inches). HAZARDS AFFECTING LAND ---------------------- None.

Subtropical Storm Theta Discussion Number 1 NWS National Hurricane Center Miami FL AL302020 300 AM GMT Tue Nov 10 2020 Over the past 12 h convection has slowly consolidated near the center of a non-tropical area of low pressure over the far northeast Atlantic. Earlier, there was a 2325 UTC ASCAT-B pass that showed that the low-level circulation had become more detached from the warm frontal boundary located to its northeast. In addition, the ASCAT pass showed that winds have increased to near 45 kt on the southeast portion of the circulation near where coldest convective cloud tops were located. Both a 2137 UTC SSMIS and 2324 UTC AMSU microwave pass showed convective banding under the cirrus canopy near where the highest winds were observed. However, water vapor satellite imagery still shows the presence of a broad upper-level low tangled up with the low-level circulation embedded in the convection. Therefore, Theta has been designated as a subtropical storm with maximum wind of 45 kt. Theta has been on a near due east heading over the last 12 h at 90/13 kt. Currently the cyclone is located south of a broad deep-layer longwave trough. This trough is expected to bypass the cyclone to the east and Theta will primarily be steered by southwesterly flow on the northern periphery of a mid-level ridge centered over the Cape Verde islands. This flow will steer Theta slowly to the east-northeast over the next 3-5 days. The track guidance is in good agreement with this solution, with only minor differences in across-track spread. There are somewhat larger differences in the along-track spread related to different forward motion, but the latest NHC track forecast elected to stay close to the track consensus at this time. Thetas structure has evolved from a frontal cyclone to a subtropical cyclone, though a frontal boundary remains nearby on the northeast side of the circulation. This boundary is expected to gradually dissipate and Theta is expected to fully transition to a tropical storm in 24 h as convection erodes the upper-level cyclonic flow overhead. The maximum sustained winds were increased slightly in the first 12 h of the forecast but are kept at 50 kt through 120 h which is on the high end of the intensity guidance. Theta is the 29th named storm in the record-breaking 2020 Atlantic Hurricane Season, breaking the previous record of 28th named storms in 2005.

Doesn't look like much chance or time for Eta to become a hurricane again Tropical Storm Eta Discussion Number 39 NWS National Hurricane Center Miami FL AL292020 900 PM CST Mon Nov 09 2020 Eta's convective structure appears to be gradually becoming better organized this evening. The center is located near the northern edge of a band that wraps around the southeastern and southern portions of the circulation. Recent subjective Dvorak data T-numbers were 3.0, which still support an initial intensity of 45 kt. With Eta's structure gradually improving and a forecast for the cyclone to remain over SSTs of around 28C and in generally low vertical wind shear conditions, some re-strengthening is likely during the next 24-36 hours. Although the NHC intensity forecast shows Eta remaining just below hurricane strength, there is a possibility that the storm will briefly regain hurricane status over the southeastern Gulf of Mexico within the next day or so. By 48 hours, when the cyclone moves over the east-central Gulf of Mexico, increasing vertical wind shear and dry mid-level air are likely to result in weakening, and like the previous forecast, the new NHC forecast indicates that Eta could weaken to a tropical depression by the end of the period. Some of the global model guidance suggests that Eta could weaken even faster than indicated below after 72 hours. Recent satellite fixes indicate that Eta is moving southwestward but a little slower than before at around 8 kt. Eta should slow its forward progress overnight and then meander over the southeastern Gulf of Mexico on Tuesday as steering current collapse. In 36-48 hours, Eta should begin moving northward between a mid-level ridge over the western Atlantic and a broad trough over the central United States. After 72 hours, the spread in the guidance increases when Eta is expected to be weaker and be steered by the low-level flow. Most of the guidance shows a northwestward to northward motion at that time period but have varying forward speed. The NHC track shows a slow north-northwest motion late in the period to account for these differences. There is lower than normal confidence in the latter portion of the track forecast given the large spread in the guidance. Key Messages: 1. Heavy rainfall from Eta will continue across portions of Cuba, the Bahamas, and southern Florida and spread north into central Florida. Additional flash and urban flooding, especially across previously inundated areas, will be possible in South Florida tonight. Flash and urban flooding will also be possible for Cuba, the Bahamas and the remainder of southern Florida over the next several days. 2. Eta could approach the Florida Gulf Coast later this week as a tropical storm, and possibly bring impacts from rain, wind, and storm surge. Interests in this area should continue to monitor the progress of Eta and updates to the forecast this week.

Tropical Depression Eta Discussion Number 25 NWS National Hurricane Center Miami FL AL292020 300 PM CST Fri Nov 06 2020 Reports from an Air Force Reserve Hurricane Hunter aircraft indicate that the center of Eta is elongated east-to-west with multiple vorticity centers present. The central pressure is near 1002 mb, and the maximum flight-level winds were 30-35 kt at 1500 ft. There were a few spot reports of 35-45 kt winds from the Stepped Frequency Microwave Radiometer, but these were in areas of heavy rain and their reliability is suspect. Based on these data, the initial intensity is kept at 30 kt. The aircraft data shows that the center is farther south than previously thought, and the initial motion is an uncertain 040/6 kt. There is no change to the previous track forecast philosophy. A developing mid- to upper-level trough over the Gulf of Mexico is expected to steer Eta northeastward for the next 48 h or so with an increase in forward speed. Between 48-72 h, the trough is forecast to become a closed low near south Florida and western Cuba, causing Eta to turn northwestward around and into the low. After 72 h, the merged system is likely to move slowly westward to northwestward. While the guidance is in good agreement on the synoptic evolution, there remain differences in the track forecast details in terms of both the heading and the forward speed, with the GFS-based guidance tending to be to the east and north of the UKMET/ECMWF/Canadian. In addition, the HWRF/HMON/Canadian are faster than the other guidance. The new forecast track overall is a little slower than the previous track, and due to the initial position the first 36 h have been shifted southward. Eta will move over the warm waters of the northwestern Caribbean during the next 48 h or so, and the upper-level divergence is forecast to be quite strong. This should allow some strengthening, although this is likely to be slowed by 20-30 kt of southwesterly vertical wind shear. The intensity forecast for this part of the cyclone's life is again similar to the previous forecast and lies near the bulk of the intensity guidance. Between 48-72 h , Eta may take on at least some subtropical cyclone characteristics as it merges with the mid- to upper-level low. The HWRF and HMON models still suggest the possibility that a tight inner wind core may develop, however, the guidance has trended weaker since this morning, and the new intensity forecast is above the bulk of the guidance. After 72 h, dry air entrainment is expected to cause the cyclone to weaken. The wind field of Eta is expected to increase in size during the next few days, and the cyclone will likely produce a large area of tropical-storm-force winds on its north side when it is near Cuba, the Florida Keys, and southern Florida. The new forecast track requires a Tropical Storm Warning for portions of Cuba at this time. Watches may be required for portions of south Florida and the Florida Keys tonight. Key Messages: 1. Heavy rainfall is diminishing across portions of Central America, although the threat of life-threatening flooding may continue, along with landslides in areas of higher terrain. Heavy rainfall from Eta will move into the Cayman islands and portions of Cuba, resulting in significant, life-threatening flash flooding and river flooding. Flash flooding and urban flooding is also possible for Jamaica and southeast Mexico. 2. Tropical storm conditions are expected this weekend in portions of the Cayman Islands and Cuba, where a Tropical Storm Warning is in effect. 3. There is an increasing risk of impacts from wind and flash and urban flooding due to heavy rainfall in portions of southern Florida, the Florida Keys, and portions of the Bahamas this weekend and early next week. Tropical Storm or Hurricane Watches will likely be issued for a portion of this area tonight.

Tropical Depression Eta Discussion Number 19 NWS National Hurricane Center Miami FL AL292020 300 AM CST Thu Nov 05 2020 Eta has become very disorganized due to its interaction with the land mass of Central America, and may no longer have a surface circulation. Based on a few surface observations, the maximum winds are estimated to be around 25 kt over the water to the north of Honduras. Eta is likely to degenerate into a post-tropical low very soon, if it hasn't done so already. Since the low is predicted to move into the northwestern Caribbean Sea by tomorrow night, some restrengthening is forecast to begin by the weekend. However the expected broad nature of the cyclone and stronger vertical shear are likely to limit strengthening over the next several days. The official intensity forecast is similar to the latest model consensus. The center is extremely difficult to locate at this time, but based on continuity the initial motion is estimated to be 300/7 kt. Eta, or its post-tropical remnant low/trough, should continue to move over land today, and then turn northward tonight while moving along the eastern side of a broader gyre. This will take the system into the Gulf of Honduras and over the northwestern Caribbean Sea on Friday. A negatively-tilted 500-mb trough/low developing over the Gulf of Mexico should induce a generally northeastward motion for the next 2-3 days and take the cyclone across portions of Cuba in 3-4 days. Thereafter, the system is forecast to rotate cyclonically around the eastern side of the 500 mb low and turn northwestward to westward by the end of the forecast period. The official forecast is a blend of the latest GFS and ECMWF predictions, but leans toward the latter model. This track could take the system near or over portions of extreme southern Florida by late this weekend or early next week, but there is low confidence in the forecast, especially at 3-5 days. Key Messages: 1. Through Monday morning, heavy rainfall from Eta will lead to catastrophic, life-threatening flash flooding and river flooding across portions of Central America, along with landslides in areas of higher terrain. Flash and river flooding is also possible across Jamaica, southeast Mexico, the Cayman Islands and western Cuba. 2. Eta is forecast to regain tropical storm strength over the northwestern Caribbean Sea late this week. Although the details of the future track and intensity of Eta are uncertain, there is an increasing risk of impacts from wind and rainfall in portions of Cuba, southern Florida and the Florida Keys this weekend and early next week.

Question -- if the LLC circulation gets disrupted by Central America, but the MLC returns over the waters, will it still be Eta? or a new TC entirely?
-
Question -- if a freeze warning was issued, doesn't that usually mean that the "growing season" is officially over for that county? Like I know there was a freeze warning for PW few days ago and they have a frost advisory tonight... just think it's a bit strange

Hurricane Eta Discussion Number 11 NWS National Hurricane Center Miami FL AL292020 400 AM EST Tue Nov 03 2020 Eta remains an extremely well-organized hurricane with a distinct eye embedded within cloud tops colder than -80C. Based on continuity from the earlier Hurricane Hunter observations and Dvorak classifications from TAFB and SAB, the current intensity estimate remains 130 kt. Images from the San Andres radar show at least one concentric eyewall, and this structure has likely stopped the rapid deepening process. Nonetheless, Eta is an extremely severe hurricane, capable of causing very high storm surges and catastrophic damage. After the center moves inland later today, rapid weakening is likely while the circulation interacts with land. The official forecast is similar to the Decay-SHIPS guidance, and shows the cyclone weakening to a depression by tomorrow. It is not certain that the surface circulation will survive after moving over Central America for the next 3 days or so. The official forecast shows the system, perhaps at first the upper-level remnant of Eta, emerging over the northwestern Caribbean Sea in the latter part of the forecast period. It should be noted that both the intensity and track at 4-5 days are highly uncertain at this time. The hurricane has slowed down and is now moving a little south of west or about 250/4 kt. This motion will take the center across the coast in the Hurricane Warning area very soon. A weak ridge to the north of Eta should cause the cyclone to move west to west-northwest, over Central America, during the next few days. By 96-120 hours, a trough developing over the Gulf of Mexico should cause the system to turn northward and northeastward but, as noted earlier, this future track is quite uncertain. Since Eta is likely to be a very slow-moving system after it makes landfall in Central America, torrential rains and inland flooding will be an extremely serious threat over the next few days. Key Messages: 1. Catastrophic wind damage is expected where Eta's eyewall moves onshore along the northeastern coast of Nicaragua this morning. Tropical-storm-force or greater winds are already occuring within the Hurricane Warning area in Nicaragua. A Tropical Storm Warning is also in effect for the northeastern coast of Honduras. 2. A catastrophic and life-threatening storm surge, along with destructive waves, are expected along portions of the northeastern coast of Nicaragua near and to the north of where the center makes landfall. Water levels could reach as high as 14 to 21 feet above normal tide levels in some parts of the hurricane warning area. Preparations to protect life and property should now be complete. 3. Through Friday evening, heavy rainfall from Eta will lead to catastrophic, life-threatening flash flooding and river flooding across portions of Central America, along with landslides in areas of higher terrain. Flash and river flooding is also possible across Jamaica, southeast Mexico, El Salvador, southern Haiti, and the Cayman Islands.
