Post-Tropical Cyclone Teddy Forecast Discussion Number 46

2020-09-23 22:37:55| National Hurricane Center (Atlantic)

Issued at 500 PM AST Wed Sep 23 2020 000 WTNT45 KNHC 232037 TCDAT5 Post-Tropical Cyclone Teddy Discussion Number 46 NWS National Hurricane Center Miami FL AL202020 500 PM AST Wed Sep 23 2020 Teddy is moving quickly north-northeastward just west of Newfoundland this afternoon as a decaying extratropical low. Maximum winds from an earlier scatterometer pass were about 50 kt, and the winds have probably come down based on pressure data from Meat Cove as the storm left Nova Scotia, so the initial wind speed is set to 45 kt. Little change in intensity is expected overnight as Teddy races near northwestern Newfoundland and southeastern Labrador overnight. The storm is then forecast to move across the Labrador Sea on Thursday and become absorbed into a powerful extratropical low, where hurricane-force winds are forecast southwest of Greenland. No changes were made to the previous track or intensity forecasts. Even after Teddy passes Nova Scotia and Newfoundland, large swells creating dangerous rip currents will linger over much of the southwestern Atlantic basin for the next few days. Key Messages: 1. The most significant hazards expected from Teddy now are dangerous waves and high winds for Newfoundland, and Tropical Storm Warnings are in effect for parts of southwestern Newfoundland. 2. Very large swells produced by Teddy are expected to affect portions of Bermuda, the Leeward Islands, the Greater Antilles, the Bahamas, the east coast of the United States, and Atlantic Canada during the next couple of days. These swells are expected to cause life-threatening surf and rip current conditions.
