Tropical Storm Beta Public Advisory Number 5
2020-09-18 22:52:49| National Hurricane Center (Atlantic)
Issued at 400 PM CDT Fri Sep 18 2020 000 WTNT32 KNHC 182052 TCPAT2 BULLETIN Tropical Storm Beta Advisory Number 5 NWS National Hurricane Center Miami FL AL222020 400 PM CDT Fri Sep 18 2020 ...DEPRESSION IN THE GULF OF MEXICO BECOMES TROPICAL STORM BETA... SUMMARY OF 400 PM CDT...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...24.3N 93.1W ABOUT 335 MI...545 KM ENE OF TAMPICO MEXICO ABOUT 280 MI...450 KM ESE OF MOUTH OF THE RIO GRANDE MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H PRESENT MOVEMENT...NNE OR 25 DEGREES AT 9 MPH...15 KM/H MINIMUM CENTRAL PRESSURE...1004 MB...29.65 INCHES WATCHES AND WARNINGS -------------------- Interests along the western Gulf of Mexico coast should monitor the progress of Beta. Storm Surge and Tropical Storm or Hurricane Watches will likely be required for portions of the western Gulf coast tonight or on Saturday. DISCUSSION AND OUTLOOK ---------------------- At 400 PM CDT (2100 UTC), the center of Tropical Storm Beta was located near latitude 24.3 North, longitude 93.1 West. Beta is moving toward the north-northeast near 9 mph (15 km/h), and this general motion is expected through Saturday. A slow westward motion is forecast to begin late Saturday or Saturday night, and this motion will likely continue into early next week. On the forecast track, the center of Beta will approach western coast of the Gulf of Mexico Sunday night and Monday. Maximum sustained winds have increased to near 40 mph (65 km/h) with higher gusts. Additional slow strengthening is expected through the weekend, and Beta could be near hurricane strength Sunday or Sunday night. Tropical-storm-force winds extend outward up to 105 miles (165 km) from the center. The estimated minimum central pressure is 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells are expected to increase and reach the coast of Texas and the Gulf Coast of Mexico over the weekend, generated by a combination of Beta and a cold front entering the northern Gulf of Mexico. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 1000 PM CDT. $$ Forecaster Beven

Tropical Storm Wilfred Forecast Discussion Number 2
2020-09-18 22:45:15| National Hurricane Center (Atlantic)
Issued at 500 PM AST Fri Sep 18 2020 000 WTNT43 KNHC 182045 TCDAT3 Tropical Storm Wilfred Discussion Number 2 NWS National Hurricane Center Miami FL AL232020 500 PM AST Fri Sep 18 2020 There haven't been a lot of changes with Wilfred today, with the northern side of the circulation looking rather dry while the center remains close to a burst of convection. The initial wind speed is kept 35 kt, closest to the TAFB classification. Wilfred could strengthen some during the next day or so before increasing upper-level westerlies winds likely begin by Sunday. A gradual weakening is expected into early next week, though the model guidance is in worse agreement than the last advisory due to the positioning of an upper-level low. The forecast continues to show the storm ending up on the convergent side of the low and dissipating, close to the previous one. Wilfred is moving west-northwestward at about 16 kt, after accounting for a re-positioning westward. Most of the guidance agrees on a scenario that maintains this track for the next few days, with a turn toward the west as the cyclones dissipates. The new forecast is closest to the GFS-based guidance. Similar to the intensity forecast, however, there are some models that suggest Wilfred could slow down and turn to the right in a couple of days if it is stronger than anticipated. FORECAST POSITIONS AND MAX WINDS INIT 18/2100Z 12.5N 34.4W 35 KT 40 MPH 12H 19/0600Z 13.2N 36.7W 40 KT 45 MPH 24H 19/1800Z 14.3N 39.7W 40 KT 45 MPH 36H 20/0600Z 15.4N 42.6W 40 KT 45 MPH 48H 20/1800Z 16.4N 45.4W 35 KT 40 MPH 60H 21/0600Z 17.1N 48.0W 30 KT 35 MPH 72H 21/1800Z 17.5N 50.0W 25 KT 30 MPH...POST-TROP/REMNT LOW 96H 22/1800Z...DISSIPATED $$ Forecaster Blake
