DISCUSSION AND OUTLOOK
----------------------
At 200 AM AST (0600 UTC), the center of Post-Tropical Cyclone Teddy
was located near latitude 43.4 North, longitude 63.5 West.  The
post-tropical cyclone is moving toward the north-northeast near 18
mph (30 km/h), and this general motion is expected to continue for
the next day or so.  On the forecast track, the center will move
over eastern Nova Scotia later today, and then near or over
Newfoundland by tonight, and be east of Labrador on Thursday.
 
Maximum sustained winds have decreased to near 75 mph (120 km/h)
with higher gusts.  Although additional weakening is likely today,
Teddy should be a strong post-tropical cyclone when it moves near
and over Nova Scotia.
 
Hurricane-force winds extend outward up to 125 miles (205 km) from
the center and tropical-storm-force winds extend outward up to 540
miles (870 km).
 
The estimated minimum central pressure is 955 mb (28.20 inches).

Discussion under AWIPS header MIATCDAT5 and WMO header WTNT45 KNHC
and on the web at https://www.hurricanes.gov/text/MIATCDAT5.shtml.
 
STORM SURGE:  A dangerous storm surge is expected to produce
significant coastal flooding near and to the east of where the
center makes landfall in Nova Scotia.  Near the coast, the surge
will be accompanied by very large and destructive waves.
 
SURF:  Large swells generated by Teddy are affecting Bermuda, the
Lesser Antilles, the Greater Antilles, the Bahamas, the east coast
of the United States, and Atlantic Canada. These swells are likely
to cause life-threatening surf and rip current conditions.  Please
consult products from your local weather office.
 
WIND:  Tropical storm conditions are occurring in the Nova Scotia
warning area.  Tropical storm conditions could begin in the
watch areas this morning.  Tropical storm conditions are expected to
begin in the Newfoundland warning area this afternoon.
 
RAINFALL: Through Thursday, Teddy is expected to produce rainfall
accumulations of 2 to 4 inches (50 to 100 mm) with isolated totals
of 6 inches (150 mm) across sections of Atlantic Canada.
