DISCUSSION AND OUTLOOK
----------------------
At 200 AM AST (0600 UTC), the center of Post-Tropical Cyclone Idalia
was located near latitude 31.7 North, longitude 64.9 West. The
post-tropical cyclone is moving toward the east near 14 mph (22
km/h) and this general trajectory at a slower forward speed is
expected through today.  A turn toward the northeast is forecast on 
Sunday.  On the forecast track, Idalia will remain near Bermuda 
today, and then begin to move away from the island on Sunday. 
 
Maximum sustained winds are near 50 mph (85 km/h) with higher
gusts. Little change in strength is forecast during the next few
days. Idalia could transition to a tropical or subtropical storm 
later today.  

Tropical-storm-force winds extend outward up to 220 miles (350 km)
from the center.  A wind gust to 40 mph (65 km/h) was recently 
reported at the LF Wade International Airport on Bermuda.  An 
elevated observing site at the National Museum of Bermuda recently 
reported sustained winds of 46 mph (74 km/h) with a gust to 54 mph 
(87 km/h). 
  
The estimated minimum central pressure is 999 mb (29.50 inches).

inches, or 75 to 125 millimeters, across Bermuda through the
weekend.  The heavy rainfall will likely cause areas of flash and
urban flooding on the island.

likely to cause life-threatening surf and rip current conditions.
