SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 500 PM AST (2100 UTC), the center of Post-Tropical Cyclone Idalia was located near latitude 32.0 North, longitude 62.7 West. Idalia is moving toward the east-northeast near 7 mph (11 km/h), and this general motion is expected to continue through tonight. A turn toward the northeast and then north at a faster forward speed is expected through early next week. Idalia will continue moving away from Bermuda tonight. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Little change in strength is forecast during the next few days. Tropical-storm-force winds extend outward up to 205 miles (335 km) from the center. The estimated minimum central pressure is 997 mb (29.44 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Idalia can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT5 and WMO header WTNT45 KNHC, and on the web at hurricanes.gov/text/MIATCDAT5.shtml WIND: Gusts to tropical storm force are likely to continue on Bermuda through tonight. SURF: Swells generated by Idalia will affect the southeastern U.S. coast and Bermuda 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. NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on this system.

000 WTNT45 KNHC 022032 TCDAT5 Post-Tropical Cyclone Idalia Discussion Number 29 NWS National Hurricane Center Miami FL AL102023 500 PM AST Sat Sep 02 2023 Winds on Bermuda have been gradually decreasing since earlier this morning, and weather stations on the island are no longer measuring sustained tropical-storm-force winds (at standard elevation). Gusts to tropical storm force will likely continue on Bermuda into tonight while Idalia pulls away from the island, but the Bermuda Weather Service has elected to discontinue the Tropical Storm Warning in favor of local warnings. Therefore, this will be the last NHC advisory on Idalia. Earlier ASCAT showed that maximum winds remain 50 kt on the northwestern side of the attached frontal boundary. Little change in strength is expected during the next few days. The extratropical cyclone is likely to occlude again in about 3 days and begin to fill, at which point weakening is expected. The NHC intensity forecast is between the HCCA and IVCN consensus aids. Idalia appears to have turned toward the east-northeast, or 075/6 kt. A shortwave trough is expected to move off the coast of New England on Sunday, causing the cyclone to turn northeastward and the northward and speed up over the next 2-3 days. Once it occludes, it is expected to slow down and meander to the southeast of Nova Scotia on days 4 and 5. Additional information on this system can be found in High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php KEY MESSAGES: 1. Swells from Idalia are forecast to cause life-threatening surf and rip current conditions along portions of the east coast of the United States through Labor Day weekend. 2. Gusts to tropical storm force are likely to continue on Bermuda through tonight.
