Last chance saloon on Wednesday for this years severe? From this morning's AFD:

New track is south of mainland FL and barely gets into the Keys

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.

Tropical Storm Eta Discussion Number 3 NWS National Hurricane Center Miami FL AL292020 400 AM EST Sun Nov 01 2020 Eta has not become appreciably better organized over the past few hours. A large convective band is evident well to the east and northeast of the estimated center, but this band does not have much curvature at this time. A small burst of deep convection is occurring near or over the center, which is likely the early stages of the development of a Central Dense Overcast. Currently, there is a significant amount of lightning in the outer band but little lightning near the center. The intensity is held at 35 kt for this advisory, in agreement with Dvorak estimates from TAFB and SAB. Eta will be moving over very warm waters of SSTs above 29 deg C and in an environment of fairly light vertical shear. Therefore, strengthening is likely. The official forecast, like the previous ones, calls for the cyclone to become a hurricane before approaching Central America. There is also a possibility of rapid strengthening, as suggested by the SHIPS Rapid Intensification Index. The NHC intensity forecast is very similar to the latest corrected consensus prediction up to the expected landfall and follows the Decay-SHIPS guidance after that point. The center location is somewhat uncertain, and my best estimate of initial motion is about the same as before, or 275/13 kt. The track forecast reasoning has not changed significantly. A mid-level ridge to the north and northwest of Eta should cause a westward or west-southwestward motion for the next few days. This would take the cyclone inland over Central America in 72 hours or so. The official track forecast is similar to the previous one, and lies near the simple model consensus and a little north of the corrected consensus. Key Messages: 1. Eta is expected to strengthen to a hurricane early next week as it approaches the coast of Central America early Tuesday, and there is a risk of storm surge, hurricane-force winds, and heavy rainfall for portions of Nicaragua and Honduras, where Hurricane Watches have been issued. Hurricane warnings could be needed for portions of those areas later today. 2. Through Thursday afternoon, heavy rainfall from Eta may lead to life-threatening flash flooding and river flooding, along with landslides in areas of higher terrain across portions of Jamaica, the Cayman Islands, the southern coast of Hispaniola, northern Honduras and northern Nicaragua.

FOR METEOROLOGISTS. 2. 6 HOUR SUMMARY AND ANALYSIS. SUPER TYPHOON 22W (GONI), LOCATED APPROXIMATELY 454 NM EAST OF MANILA, PHILIPPINES, HAS TRACKED WEST-SOUTHWESTWARD AT 12 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A COMPACT, POWERFUL SYSTEM WITH A WELL DEFINED 7 NM EYE. WHILE STILL COMPACT IN NATURE IT HAS INCREASED IN SIZE OVER THE PAST 6 HOURS. THE INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE WELL DEFINED EYE FEATURE IN THE MSI LOOP. THE INITIAL INTENSITY OF 160 KTS IS FURTHER PLACED WITH HIGH CONFIDENCE AND IS HEDGED SLIGHTLY ABOVE MULTI-AGENCY DVORAK CURRENT INTENSITY ESTIMATES OF T7.5 (155 KTS, PGTW AND RJTD) BASED ON RECENT ADVANCED DVORAK TECHNIQUE CURRENT INTENSITY ESTIMATES OF T7.6 (158 KTS). ANALYSIS OF THE EYE WALL STRUCTURES IN SEVERAL MICROWAVE IMAGES SUGGESTS THAT AN EYE WALL REPLACEMENT CYCLE (ERC) IS IMMINENT. DESPITE THIS, THE OVERALL CONVECTIVE STRUCTURE, CLOUD TOP AND EYE TEMPERATURES ARE IN AGREEMENT THAT A WEAKENING PHASE, TYPICAL OF ERC, HAS NOT YET COMMENCED. STY GONI HAS CONTINUED TO TRACK ALONG THE SOUTHERN PERIPHERY OF THE SUBTROPICAL RIDGE (STR) POSITIONED OVER SOUTHERN CHINA AND THROUGH AN OVERALL FAVORABLE ENVIRONMENT WITH VERY WARM (30 DEG CELSIUS) WATERS, LOW (10-15 KNOTS) VWS AND ROBUST RADIAL OUTFLOW. POLEWARD OUTFLOW REMAINS ESPECIALLY STRONG. 3. FORECAST REASONING. A. NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE PREVIOUS PROGNOSTIC REASONING MESSAGE. B. STY GONI WILL CONTINUE TO TRACK GENERALLY SOUTHWESTWARD TO SOUTH-SOUTHWESTWARD OVER THE NEXT 24 HOURS. THE ENVIRONMENT WILL REMAIN OVERALL FAVORABLE FOR DEVELOPMENT, HOWEVER A GRADUAL WEAKENING IS FORECAST DURING THIS TIME DUE TO THE ERC AND, DECREASING POLEWARD OUTFLOW ASSOCIATED WITH THE ONGOING REPOSITIONING OF THE STEERING RIDGE, AND A SMALL INCREASE IN VWS (15-20 KTS). STY GONI WILL THEN MAKE LANDFALL ALONG THE COAST OF LUZON, EAST OF MANILA, BETWEEN TAU 24 AND TAU 36 AS A SIGNIFICANT TROPICAL CYCLONE. AS THE SYSTEM TRANSITS ACROSS LUZON AND INTO THE SOUTH CHINA SEA, IT WILL FURTHER WEAKEN DUE TO TERRAIN INTERACTION TO AN INTENSITY OF 75 KTS BY TAU 48. AS THE SYSTEM TRACKS OVER THE SOUTH CHINA SEA BETWEEN TAU 48 AND TAU 72, IT WILL STEADILY WEAKEN TO AN INTENSITY OF 60 KTS DUE TO CONTINUED MODERATE TO HIGH (20-25 KTS) VWS. NUMERICAL MODEL GUIDANCE IS IN GOOD AGREEMENT DURING THIS INITIAL PORTION OF THE JTWC FORECAST TRACK, WITH A TOTAL SPREAD IN ACROSS TRACK MODEL SOLUTIONS OF 150 NM AT TAU 72. SPECIFICALLY THE NAVGEM TRACK LIES NORTHWARD OF THE OTHER JTWC MULTI-MODEL CONSENSUS MEMBERS. AS SUCH, THIS INITIAL PORTION OF THE JTWC FORECAST IS PLACED SLIGHTLY SOUTH OF THE JTWC MULTI-MODEL CONSENSUS WITH OVERALL HIGH CONFIDENCE. C. IN THE EXTENDED FORECAST, THE SYSTEM WILL TRACK WESTWARD ALONG THE SOUTHERN PERIPHERY OF THE DEEP-LAYER STR POSITIONED TO THE NORTH THROUGH THE END OF THE FORECAST, AND MAKE A SECOND LANDFALL ALONG THE CENTRAL VIETNAM COAST BETWEEN TAU 96 AND TAU 120. THE SYSTEM WILL CONTINUE TO WEAKEN UNDER THE INFLUENCE OF MODERATE VWS AND CONTINUED ENTRAINMENT OF DRY MID-LEVEL AIR. NUMERICAL MODEL TRACK GUIDANCE HAS CONVERGED SINCE THE LAST FORECAST WITH ONLY NAVGEM PREDICTING A NORTHWESTWARD TRACK TOWARDS HAINAN. THE REMAINING MEMBERS OF THE JTWC MULTI-MODEL CONSENSUS AGREE WITH A WESTWARD TRACK DURING THIS TIME. AS SUCH THE JTWC FORECAST TRACK FOR THE REMAINDER OF THE FORECAST IS PLACED SOUTH OF THE MULTI-MODEL CONSENSUS WITH OVERALL FAIR CONFIDENCE TO OFFSET THE NORTHWESTWARD BIAS CONTRIBUTED BY THE NAVGEM TRACK.// NNNN
