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. For additional
