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.
