At 200 PM AST (1800 UTC), the center of Tropical Storm Philippe was
located near latitude 22.0 North, longitude 65.8 West.  Philippe is
moving toward the north-northwest near 9 mph (15 km/h), and this

faster forward speed is forecast to begin tonight and continue into
the weekend.  On the forecast track, the center of Philippe will
approach Bermuda Thursday night and Friday.
 
Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. 
Little change in strength is forecast during the next couple of 
days.  Some strengthening is possible late this week.
 
Tropical-storm-force winds extend outward up to 150 miles (240 km)
to the east of the center.  A saildrone located about 110 miles 
(175 km) southeast of Philippe's center recently reported a 
sustained wind of 33 mph (54 km/h) and a gust to 42 mph (68 km/h).
 
The minimum central pressure based on dropsonde and buoy data is
