Tropical Depression Eta Public Advisory Number 21A
2020-11-06 00:30:25| National Hurricane Center (Atlantic)
Issued at 600 PM CST Thu Nov 05 2020 000 WTNT34 KNHC 052330 TCPAT4 BULLETIN Tropical Depression Eta Intermediate Advisory Number 21A NWS National Hurricane Center Miami FL AL292020 600 PM CST Thu Nov 05 2020 ...ETA CAUSING HEAVY RAINS AND LIFE-THREATENING FLOODING OVER PORTIONS OF CENTRAL AMERICA... SUMMARY OF 600 PM CST...0000 UTC...INFORMATION ---------------------------------------------- LOCATION...16.0N 87.8W ABOUT 65 MI...100 KM WNW OF LA CEIBA HONDURAS MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...NNW OR 340 DEGREES AT 8 MPH...13 KM/H MINIMUM CENTRAL PRESSURE...1004 MB...29.65 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Watch is in effect for... * The Cayman Islands A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. The governments of Nicaragua and Honduras continue to issue warnings on heavy rain and flooding in those countries, and interests in Nicaragua and Honduras should continue to monitor the progress of this system. Interests in Belize and western Cuba should also monitor the progress of this system, as Tropical Storm Watches may be required for portions of western Cuba later tonight or on Friday. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 600 PM CST (0000 UTC), the center of Tropical Depression Eta was located near latitude 16.0 North, longitude 87.8 West. The depression is moving toward the north-northwest near 8 mph (13 km/h), and a turn toward the north is forecast during the next several hours. A turn toward the northeast is expected on Friday, with this motion continuing through Saturday night. On the forecast track, the center of Eta will be over the western Caribbean Sea through Friday, approach the Cayman Islands Saturday and Saturday night, and be near Cuba on Sunday. Maximum sustained winds remain near 35 mph (55 km/h) over water, with higher gusts. Strengthening is forecast, and Eta is expected to re-gain tropical storm strength on Friday. The estimated minimum central pressure based on nearby surface observations is 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Eta can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4, WMO header WTNT44 KNHC, and on the web at www.hurricanes.gov/text/MIATCDAT4.shtml. RAINFALL: Eta is expected to produce the following rainfall amounts through Tuesday morning: Portions of Central America: An additional 5 to 10 inches (125 to 255 mm), isolated maximum storm totals of 40 inches (1000 mm) in eastern Honduras and eastern Nicaragua. Southeastern Mexico and Jamaica: An additional 2 to 5 inches (50 to 125 mm), isolated maximum storm totals of 15 inches (380 mm). The Cayman Islands into portions of Cuba: 10 to 20 inches (255 to 510 mm), isolated maximum totals of 30 inches (760 mm). This rainfall will lead to catastrophic, life-threatening flash flooding and river flooding, along with landslides in areas of higher terrain of Central America. Significant, life-threatening flash flooding and river flooding is possible in the Cayman Islands and Cuba. Flash flooding and river flooding is expected for Jamaica and southeast Mexico. WIND: Tropical storm conditions are possible in the Cayman Islands Saturday or Saturday night. SURF: Swells generated by Eta are expected to affect portions of the coast of Central America and the Yucatan Peninsula of Mexico during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

Tropical Storm Odalys Forecast Discussion Number 9
2020-11-05 21:54:25| National Hurricane Center (East Pacific)
Issued at 100 PM PST Thu Nov 05 2020 000 WTPZ45 KNHC 052054 TCDEP5 Tropical Storm Odalys Discussion Number 9 NWS National Hurricane Center Miami FL EP202020 100 PM PST Thu Nov 05 2020 Deep convection associated with Odalys has largely dissipated over the past 6-9 h with just a remnant swirl of low clouds surrounding the center. Satellite estimates from SAB and TAFB continue to decrease and a recent ASCAT pass confirmed that the wind field has begun to spin down, with maximum sustained winds near 35 kt. As anticipated, the combination of high southwesterly vertical wind shear greater than 30 kt and dry mid-level air around 40 percent as diagnosed from ECMWF-SHIPS guidance has lead to a collapse of deep central convection. Even though sea surface temperatures under Odalys remain marginally warm around 26 C, vertical wind shear and mid-level dry air are forecast to become even more hostile over the next 24 h. Therefore, the latest official forecast now anticipates Odalys to become a remnant low in 24 h. Degeneration to a remnant low could occur as quickly as this evening if organized deep convection does not redevelop soon. The initial motion of the cyclone is estimated near 280/6 kt, and a due westward motion is expected within the next few hours. Odalys is now a shallow cyclone, and will primarily be steered by low-level northeasterly trade wind flow, gradually bending from a west to southwest heading over the next 24-36 h. The NHC forecast track shows a slightly sharper turn to the the southwest now that the cyclone has become more shallow, but the official track remains near the track guidance consensus.
