DISCUSSION AND OUTLOOK
----------------------
At 200 AM AST (0600 UTC), the center of Tropical Storm Philippe was 
located near latitude 18.0 North, longitude 62.4 West.  Philippe is 
moving toward the west-northwest near 7 mph (11 km/h), and a 
general northwestward motion is forecast to begin later today.  On 
the forecast track, the center of Philippe is expected to continue 
passing near the northern Leeward Islands this morning, and then 
begin moving north of those islands later today.  However, the 
strongest winds and heaviest rains will likely occur in the islands 
to the south of the center.  A turn toward the north-northwest is 
forecast by tonight, followed by a northward motion on Wednesday.
 
Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. 
Little change in strength is forecast during the next day or two, 
but Philippe could begin to intensify around the middle of the week.
 
Tropical-storm-force winds extend outward up to 175 miles (280 km)
primarily to the east and southeast of the center.
 
The minimum central pressure estimated from Air Force Hurricane
Hunter aircraft observations is 1001 mb (29.56 inches).

Atlantic coasts of the northern Leeward Islands, the Virgin
Islands, and Puerto Rico through midweek. These swells are
likely to cause life-threatening surf and rip current conditions.
