DISCUSSION AND OUTLOOK
----------------------
At 200 PM AST (1800 UTC), the center of Tropical Storm Philippe was
located by an Air Force Reserve Hurricane Hunter near latitude 17.3
North, longitude 61.0 West. Philippe is moving toward the northwest
near 7 mph (11 km/h), and this general motion is anticipated 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 tonight. The
strongest winds and heavy rains will likely occur in the islands
after the center passes.

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 of the center.

The estimated minimum central pressure is 1000 mb (29.53 inches)
based on dropsonde data.

RAINFALL:  Philippe is forecast to produce the following rainfall
amounts through Tuesday:

Barbuda and Antigua: 4 to 6 inches

Rest of Leeward Islands: 2 to 4 inches

This rainfall may result in isolated to scattered flash flooding.

WIND:  Tropical storm conditions are expected in the warning
area and possible in the watch area beginning this evening.

SURF:  Swells generated by Philippe will affect portions of the
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.
Please consult products from your local weather office.
