Issued at 1100 PM AST Wed Sep 23 2020 000 WTNT45 KNHC 240243 TCDAT5 Post-Tropical Cyclone Teddy Discussion Number 47 NWS National Hurricane Center Miami FL AL202020 1100 PM AST Wed Sep 23 2020 Teddy is accelerating over the northeastern Gulf of St. Lawrence and will move over the Strait of Belle Isle later, while continuing to fill/decay as an extratropical cyclone. The initial intensity is set at 45 kt, and this is based on the various surface wind and pressure observations along the west coast of Newfoundland from Channel-Port aux Basques northward to Port Saunders and the Straits. Teddy is forecast to maintain its current intensity and motion, with some further increase in forward speed, and merge with a larger, stronger high-latitude extratropical low near the Labrador Sea on Thursday. 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. This will be the last NHC advisory on Teddy.
