toward the northeast and then north at a faster forward speed is 
expected through early next week.  Idalia will continue moving away 
from Bermuda tonight.
 
Maximum sustained winds are near 60 mph (95 km/h) with higher gusts.
Little change in strength is forecast during the next few days.
 
Tropical-storm-force winds extend outward up to 205 miles (335 km)
from the center.
 
The estimated minimum central pressure is 997 mb (29.44 inches).

Key messages for Idalia can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT5 and WMO header WTNT45 KNHC,
and on the web at hurricanes.gov/text/MIATCDAT5.shtml
 
WIND:  Gusts to tropical storm force are likely to continue on
Bermuda through tonight.
 
SURF:  Swells generated by Idalia will affect the southeastern U.S.
coast and Bermuda during the next couple of days.  These swells are
likely to cause life-threatening surf and rip current conditions.

Post-Tropical Cyclone IDALIA Forecast Discussion

Post-Tropical Cyclone Idalia Discussion Number  29
NWS National Hurricane Center Miami FL       AL102023
500 PM AST Sat Sep 02 2023
 
Winds on Bermuda have been gradually decreasing since earlier this 
morning, and weather stations on the island are no longer measuring 
sustained tropical-storm-force winds (at standard elevation).  
Gusts to tropical storm force will likely continue on Bermuda into 
tonight while Idalia pulls away from the island, but the Bermuda 
Weather Service has elected to discontinue the Tropical Storm 
Warning in favor of local warnings.  Therefore, this will be the 
last NHC advisory on Idalia.

Earlier ASCAT showed that maximum winds remain 50 kt on the 
northwestern side of the attached frontal boundary.  Little change 
in strength is expected during the next few days.  The 
extratropical cyclone is likely to occlude again in about 3 days 
and begin to fill, at which point weakening is expected.  The NHC 
intensity forecast is between the HCCA and IVCN consensus aids.

Idalia appears to have turned toward the east-northeast, or 075/6 
kt.  A shortwave trough is expected to move off the coast of New 
England on Sunday, causing the cyclone to turn northeastward and 
the northward and speed up over the next 2-3 days.  Once it 
occludes, it is expected to slow down and meander to the southeast 
of Nova Scotia on days 4 and 5.

Additional information on this system can be found in High Seas
Forecasts issued by the National Weather Service, under AWIPS
header NFDHSFAT1, WMO header FZNT01 KWBC, and online at 
ocean.weather.gov/shtml/NFDHSFAT1.php
 
 
KEY MESSAGES:
 
1. Swells from Idalia are forecast to cause life-threatening surf
and rip current conditions along portions of the east coast of the
United States through Labor Day weekend.

2. Gusts to tropical storm force are likely to continue on Bermuda 
through tonight.
