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).
