1100 AM AST Sat Sep 24 2022
Fiona continues to produce hurricane-force winds, heavy rains,
storm surge, and rough marine conditions across Atlantic Canada and
the surrounding waters. Surface observations suggest that the
minimum pressure has been rising, and is now estimated to be 
about 945 mb, which is still extraordinarily low.  The maximum 
winds of the storm are decreasing and are estimated to be near 70 
Fiona is now an occluded low, and it has slowed down.  The initial
motion is estimated to be northward at 22 kt.  A slower northward
motion is forecast during the next few days, taking the center of
the system across the Gulf of St. Lawrence through tonight, across
Labrador early Sunday, and into the Labrador Sea by Sunday night.
The NHC track forecast is just a touch to the west of the previous
Winds are expected to fall below hurricane strength later today,
but the cyclone is still forecast to be a potent low for the next
day or so while it continues to affect Atlantic Canada.  NHC will
continue to issue forecasts for Fiona until gale-force winds end
along the Atlantic Canada coastline.
Key Messages:
1. Fiona is forecast to continue to affect portions of Atlantic
Canada during the next day or so, and significant impacts
from high winds, storm surge, and heavy rainfall are expected.
Hurricane and Tropical Storm Warnings are in effect for much of
Atlantic Canada.

2. Heavy rains from Fiona are expected to continue to impact 
portions of Nova Scotia, Prince Edward Island, and western 
Newfoundland today, persisting across eastern Quebec and Labrador 
into Sunday. This rainfall is expected to produce flooding, some of 
which could be significant. 
3. Large swells generated by Fiona are expected to cause
life-threatening surf and rip current conditions along the coast of
the northeast United States, Bermuda, and Atlantic Canada during
the next couple of days.
