Post-Tropical Cyclone Teddy Discussion Number  45
NWS National Hurricane Center Miami FL       AL202020
1100 AM AST Wed Sep 23 2020

Surface observations indicate that Teddy made landfall this morning
near Ecum Secum, Nova Scotia, near 1200 UTC with estimated maximum
sustained winds of 65 mph and a minimum pressure of 964 mb.  Since
then, the storm has continued to race across Nova Scotia and is
slowly weakening.  The initial wind speed is set to 50 kt.  Teddy
should move north-northeastward across the Gulf of St. Lawrence this
afternoon then move near Newfoundland by tonight.  After passing
east of Labrador on Thursday, the global models show Teddy merging
with another large extratropical low over the north Atlantic. No
significant changes were made to the previous track or intensity
forecasts, which are similar to a blend of the GFS and ECMWF models.

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 hazard expected from Teddy today is large
destructive waves along the southeastern coast of Nova Scotia.
Tropical Storm Watches and Warnings are in effect for portions of
Nova Scotia, Newfoundland, Prince Edward Island and the Magdalen
Islands, and heavy rainfall across Atlantic Canada is expected
through Thursday.

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 few days. These swells are expected to cause
life-threatening surf and rip current conditions.
