Tropical Storm Eta Forecast Discussion Number 17
2020-11-04 21:46:35| National Hurricane Center (Atlantic)
Issued at 300 PM CST Wed Nov 04 2020 000 WTNT44 KNHC 042046 TCDAT4 Tropical Storm Eta Discussion Number 17 NWS National Hurricane Center Miami FL AL292020 300 PM CST Wed Nov 04 2020 Eta continues to weaken as it moves from Nicaragua into Honduras. There is little convection left near the center, and the strongest convection remains in bands well removed from the center. As before, there are no wind observations available near the center of Eta at this time, so the initial intensity is reduced to a uncertain 35 kt. The initial motion is westward or 275/6. A mid-level ridge to the north of the cyclone should steer it on a generally west- northwestward track during the next 24 h or so. After that time, a mid- to upper-level trough moving over the central and eastern Gulf of Mexico is expected to cause Eta or is remnants to turn northward and then northeastward, Then, by 120 h, the cyclone is likely to move northward or northwestward on the eastern side of the trough as it cuts off into a closed low. The track guidance remains in reasonable agreement with this scenario, However, there remains some spread on when and where the various turns will occur, and there has also been an eastward shift in the guidance envelope after 36 h. The new forecast track is shifted to the east of the previous track after 36 h, and at 72 and 96 h it lies a little to the west of the various consensus models, Eta will continue to weaken while it crosses Honduras, and it is expected to decay to a remnant low before it reaches the Gulf of Honduras or the northwestern Caribbean Sea. Re-development is expected once the center is over the water. However, interaction with the aforementioned trough could result in a structure that is more subtropical or hybrid, as suggested by the UKMET, than a classical tropical cyclone, as suggested by the ECMWF. The new intensity forecast will follow the previous forecast and go with a gradual intensification that follows the general trend of the model guidance. However, the intensity forecast again lies a little below the intensity consensus. Although it is weakening, Eta will continue to produce heavy rainfall and flooding over portions of Central America. 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 before it moves across portions of Cuba and approaches southern Florida this weekend. While it is too soon to determine the exact timing, magnitude, and location of possible impacts from wind and rainfall, interests in Cuba, southern Florida and the Florida Keys should monitor the progress of Eta through the week.

Tropical Storm Odalys Forecast Discussion Number 5
2020-11-04 21:36:08| National Hurricane Center (East Pacific)
Issued at 100 PM PST Wed Nov 04 2020 000 WTPZ45 KNHC 042036 TCDEP5 Tropical Storm Odalys Discussion Number 5 NWS National Hurricane Center Miami FL EP202020 100 PM PST Wed Nov 04 2020 The center of Odalys has become easier to find this afternoon. A well-defined low-level center has become apparent on visible satellite imagery, about 50 nm southwest of the deepest convection. Despite this somewhat disheveled appearance, a series of ASCAT passes earlier this afternoon found winds of 35-40 kt in a band north of the center. Allowing for a bit of instrument undersampling, and blending the latest SAB and TAFB satellite estimates, the initial intensity was raised slightly to 40 kt for this advisory. Odalys continues to move northwestward this afternoon at 315/15 kt. The track forecast philosophy has remained largely unchanged. The storm will continue to head northwest in the short-term, situated between a deep-layer ridge over Mexico and a mid to upper-level trough located to its northeast. This same trough will likely generate high enough vertical wind shear to cause the low and mid level centers of Odalys to completely separate in the next 24 h, resulting in the low-level center of Odalys to bend west and then west-southwest as it comes under the influence of the low-level easterly trade winds. The latest track guidance is in good agreement on this evolution with only minor speed differences after Odalys becomes a shallow vortex and only small adjustments were made to the official forecast track. Odalys may maintain its current intensity over the next 12 h if it is able to maintain active downshear convection. Thereafter, the southwesterly vertical wind shear is forecast to increase above 35 kt in the latest GFS-based SHIPS guidance. This should import very dry mid-level air near the center and will likely choke off any remaining convective bursts. Odalys is expected to become a shallow remnant low on Friday afternoon, if not sooner.
