Tropical Storm Henri Discussion Number 18 NWS National Hurricane Center Miami FL AL082021 500 AM EDT Fri Aug 20 2021 Henri's low-level center has been peaking out from under the north side of the deep convective mass, resulting from continued 20-25 kt of northerly shear. Maximum winds are still estimated to be 55 kt based on T3.5 Dvorak estimates from TAFB and SAB. Henri still has a motion toward the west-northwest, or 300/8 kt, but it is about ready to make the sharp right turn that we've been expecting. A shortwave trough currently over the central Appalachians is forecast to close off by Saturday, with Henri accelerating northward on the east side of this feature through the weekend. Some global models show Henri merging with the mid-/upper-level low as the cyclone approaches southern New England, which induces a slight bend of Henri's forecast track to the left. Nearly all track models now show Henri's center reaching the coast of southern New England, and the new NHC track forecast has been nudged westward in the direction of HCCA and the other consensus aids. After day 3, Henri is forecast to eject northeastward across the Gulf of Maine toward Atlantic Canada. The strong shear affecting Henri is forecast to begin weakening later today, and SHIPS diagnostics indicate that it could drop to less than 10 kt in about 36 hours. In addition, Henri will be traversing very warm waters for the next 48 hours before it crosses the north wall of the Gulf Stream. Therefore, strengthening is anticipated for the next 2 days, with Henri likely to become a hurricane by Saturday. After 48 hours, Henri's expected slower motion over the colder water south of New England should induce quick weakening, but it may not be quick enough to keep Henri from reaching the coast as a hurricane. Faster weakening is anticipated after Henri's center moves over land, and simulated satellite imagery from the GFS and ECMWF models suggest that deep convection could dissipate by day 4, making Henri a post-tropical low at that time. Global models suggest that Henri may dissipate by day 5, but for the time being a day 5 point is being kept for continuity. Based on the new forecast, tropical-storm-force wind radii will be approaching the coast of southern New England in about 48 hours. Given the still-present uncertainties in Henri's future track and intensity and the hazards that the storm may cause, storm surge and hurricane watches are now being issued for portions of Long Island, Connecticut, Rhode Island, and southeastern Massachusetts. Users are reminded to not focus on the exact forecast points as impacts will extend far from the center. Key Messages: 1. Henri is forecast to be near the northeast coast of the U.S. on Sunday and Monday, and the risks of storm surge, wind, and rain impacts in portions of southern New England and eastern Long Island are increasing. Hurricane and storm surge watches are now in effect for portions of Long Island, Connecticut, Rhode Island, and southeastern Massachusetts. Additional watches or warnings may be required later today. 2. Swells from Henri will begin to reach much of the east coast of the U.S. and Atlantic Canada by the end of the week and continue through the weekend. These swells could cause life-threatening surf and rip currents. 3. Heavy rainfall may lead to flash, urban, and small stream flooding over portions of southern New England Sunday into Monday.

Then why does the 11pm disco say otherwise? " Transition to a post-tropical storm is expected to begin shortly thereafter which should be sometime in the 96-h to 120-h points as deep convection ceases over the storm over cold SSTs As noted previously, the wind field of Henri is expected to expand, especially as it interacts with a mid-latitude trough located to its west. Therefore, users are reminded to not focus on the exact forecast points as impacts will extend far from the center. "

Hurricane Watches coming shortly I bet on the 5am adv

Do not want

Maybe the ghost of James is willing this up to you guys? Sorry if that causes an issue with my post... but you know he would relish this

Making landfall at 80mph... and might be one of those rare (I think? Someone correctvme if I'm wrong) TCs to become a new storm in the Pacific basin Hurricane Grace Discussion Number 24 NWS National Hurricane Center Miami FL AL072021 400 AM CDT Thu Aug 19 2021 After a brief convective hiatus between 0400-0700 UTC, deep convection in the inner-core region has increased and become better organized during the past couple of hours. An Air Force Reserve Hurricane Hunter aircraft investigating Grace more than 4 hours ago reported a central pressure of 986 mb -- down 2 mb from previous passes -- and a maximum 700-mb flight-level wind speed of 74 kt on its last leg northbound around 0500 UTC. The 74-kt flight-level wind equates to about a 67-kt surface wind speed. These data supported maintaining a 70-kt intensity at 0600 UTC. The upper-level outflow remains symmetrical and has been expanding somewhat over the past few hours. The initial motion is 280/15 kt based on the earlier recon fixes and passive microwave satellite data. Grace should continue to move generally westward for the next 48 hours, crossing the coast of the eastern Yucatan Peninsula within the next couple of hours, followed by a track across the Yucatan and emergence over the Bay of Campeche by 24 hours, with a subsequent landfall along the eastern coast of mainland Mexico shortly after the 48-hour forecast period. This track scenario is consistent with the latest 0000 UTC global and regional models, which show the strong deep-layer ridge to the north of Grace maintaining its expansive presence across the western Atlantic, Gulf of Mexico, and northern Mexico. After the second landfall, Grace is expected to turn west-southwestward and dissipate over the mountains of central Mexico by 72 hours. The new NHC forecast track is similar to the previous advisory track, and lies along the northern edge of the tightly packed consensus track models. Given the recent improvement in Grace's inner-core convective structure noted in high-resolution infrared satellite imagery, some slight strengthening to 75 kt could still occur just prior to landfall this morning. Weakening will commence once Grace moves inland over Yucatan, with re-strengthening expected after the cyclone emerges over the Bay of Campeche where the vertical wind shear is forecast to decrease below 10 kt. Grace is expected to be a hurricane when the second landfall occurs along the coast of mainland Mexico, with the cyclone possibly reaching a peak intensity of 75 kt shortly after the 48-hour period. After final landfall in mainland Mexico, Grace should quickly weaken and dissipate over the mountains of Mexico by 72 hours, if not sooner. The remnants of Grace are expected to emerge over the eastern North Pacific and possibly re-develop there, but the uncertainty of whether this will be the original center or a new center precludes forecast points over the Pacific at this time. A Hurricane Warning will likely be required for portions of the Hurricane Watch area of mainland Mexico later this morning or afternoon. Key Messages: 1. Hurricane conditions and a dangerous storm surge are expected in portions of the Hurricane Warning area in the eastern Yucatan Peninsula of Mexico during the next several hours. Preparations to protect life and property should be rushed to completion. 2. There is an increasing risk of hurricane conditions and dangerous storm surge in portions of eastern mainland Mexico beginning late Friday, and a Hurricane Watch is in effect for part of this area. 3. Through the weekend, heavy rainfall across central and northern portions of the Yucatan Peninsula and Veracruz State should lead to flash and urban flooding. In addition, the heavy rainfall from Grace will be capable of producing mudslides in Veracruz.
