Issued at 200 AM AST Sat Sep 12 2020 000 WTNT32 KNHC 120544 TCPAT2 BULLETIN Tropical Storm Paulette Intermediate Advisory Number 21A NWS National Hurricane Center Miami FL AL172020 200 AM AST Sat Sep 12 2020 ...PAULETTE EXPECTED TO QUICKLY STRENGTHEN TO A HURRICANE SATURDAY... ...EXPECTED TO BRING HAZARDOUS CONDITIONS TO BERMUDA BY SUNDAY NIGHT... SUMMARY OF 200 AM AST...0600 UTC...INFORMATION ---------------------------------------------- LOCATION...26.4N 55.5W ABOUT 690 MI...1115 KM ESE OF BERMUDA MAXIMUM SUSTAINED WINDS...70 MPH...110 KM/H PRESENT MOVEMENT...NW OR 310 DEGREES AT 16 MPH...26 KM/H MINIMUM CENTRAL PRESSURE...987 MB...29.15 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Watch is in effect for... * Bermuda A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 200 AM AST (0600 UTC), the center of Tropical Storm Paulette was located near latitude 26.4 North, longitude 55.5 West. Paulette is moving toward the northwest near 16 mph (26 km/h). A west-northwestward or northwestward motion at a slightly slower forward speed is expected through the weekend, followed by a turn toward the north on Monday. The center of Paulette is forecast to move near Bermuda Sunday night and Monday. Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Additional strengthening is anticipated and Paulette is forecast to become a hurricane later today. Tropical-storm-force winds extend outward up to 205 miles (335 km) from the center. The estimated minimum central pressure is 987 mb (29.15 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Paulette can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2, WMO header WTNT42 KNHC, and on the web at https://www.hurricanes.gov/text/MIATCDAT2.shtml. WIND: Tropical storm conditions could begin to affect Bermuda and the nearby waters by Sunday night. Hurricane conditions could begin in that area late Sunday or early Monday. RAIN: Paulette may bring periods of heavy rain to Bermuda through Monday, with rainfall accumulations of 2 to 4 inches with maximum amounts of 6 inches possible. SURF: Swells generated by Paulette are affecting portions of the Leeward Islands and will continue to spread westward to portions of the Greater Antilles, Bahamas, Bermuda, and the southeastern United States into the weekend. 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 500 AM AST. $$ Forecaster Roberts/Brown

Tropical Storm Paulette Forecast Discussion Number 21
2020-09-12 04:53:37| National Hurricane Center (Atlantic)
Issued at 1100 PM AST Fri Sep 11 2020 000 WTNT42 KNHC 120253 TCDAT2 Tropical Storm Paulette Discussion Number 21 NWS National Hurricane Center Miami FL AL172020 1100 PM AST Fri Sep 11 2020 Paulette remains sheared and asymmetric, with all its deep convection north of its low-level center of circulation. Despite the shear, ASCAT-B data that just arrived showed maximum winds near or just over 55 kt. Since that instrument tends to under-sample the maximum winds, the initial intensity is increased to 60 kt. An upper-level low located to the west of Paulette is responsible for the southerly shear currently affecting the cyclone. Global model forecasts suggest that the shear will continue for another day or so, and only slight strengthening is likely through that period. By Sunday, the upper-level low will move farther southwest and the tropical cyclone will encounter a very favorable upper-air pattern. Paulette will likely strengthen further in response, possibly at a fast rate. All of the intensity guidance indicates that Paulette will be a hurricane when it nears Bermuda early Monday, and it could approach major hurricane strength early next week. The NHC intensity forecast has not changed since the last advisory. It is worth mentioning that Paulette could experience a period of slow development for the next 24 hours, followed by quick intensification, rather than the more steady strengthening shown by the NHC forecast. It is also important to note that the average NHC intensity errors are around 10-15 kt at 48-72 h, the range at which Paulette will likely be nearest to Bermuda. Paulette has jogged slightly right of track during the past few hours, but the overall NHC forecast track is not different from the previous advisory. A building mid-level ridge to the north of Paulette will likely steer the tropical storm generally west-northwestward or northwestward for the next 2-3 days. The cyclone is then expected to turn northeastward and accelerate in that direction ahead of a mid-latitude trough. The model spread remains relatively low, especially for the first few days. Confidence is high that Paulette will move near Bermuda early Monday, though it is still too soon to specify exactly how close it will get. The NHC forecast is based heavily on the TVCA and HCCA consensus aids and is not far from any of the global model forecast. Key Messages: 1. Paulette is expected to approach Bermuda as a hurricane on Sunday and Monday. A prolonged period of strong winds, storm surge, and heavy rainfall on Bermuda beginning Sunday night is becoming more likely. A tropical storm watch is in effect and a hurricane watch could be required for the island early Saturday. 2. Swells produced by Paulette are affecting portions of the Leeward Islands and will continue to spread westward to the Greater Antilles, the Bahamas, Bermuda, and the southeastern United States into the weekend. These swells could cause life-threatening surf and rip current conditions.
