DISCUSSION AND OUTLOOK
----------------------
At 500 PM AST (2100 UTC), the center of Tropical Storm Philippe was
located near latitude 17.6 North, longitude 61.5 West. Philippe is
moving toward the northwest near 7 mph (11 km/h), and this general
motion is anticipated through early Tuesday. On the forecast track, 
the center of Philippe is expected to pass near the northern 
Leeward Islands tonight and north of those islands on Tuesday. The 
strongest winds and heavy rains will likely occur in the islands 
after the center passes. A turn toward the north-northwest is 
forecast to occur by late Tuesday, followed by a northward motion 
on Wednesday. 
 
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)
from the center.
 
The estimated minimum central pressure is 999 mb (29.50 inches).
