DISCUSSION AND OUTLOOK
At 800 AM AST (1200 UTC), the center of Tropical Storm Philippe was
located by an Air Force Reserve Hurricane Hunter aircraft near
latitude 17.0 North, longitude 60.5 West. Philippe is moving toward
the west-northwest near 7 mph (11 km/h), and a northwestward motion
is expected to resume later today through early Tuesday. A turn
toward the north-northwest is forecast to occur by late Tuesday,
followed by a northward motion on Wednesday. On the forecast
track, the center of Philippe is expected to pass near or just
northeast of the northern Leeward Islands later today and tonight.
Maximum sustained winds remain near 50 mph (85 km/h) with higher
gusts. Little change in strength is forecast during the next day or
so, but Philippe could begin to intensify more significantly around
the middle of the week.
Tropical-storm-force winds extend outward up to 175 miles (280 km),
primarily east and southeast of the center.
The estimated minimum central pressure is 998 mb (29.47 inches).
