Philippe is moving toward the northwest near 8 mph (13 km/h). A slow west-northwestward to northwestward motion is forecast during the next day or so, followed by a slower general westward motion by this weekend.
Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Little change in strength is forecast during the next day or so, with slow weakening forecast this weekend.
Tropical-storm-force winds extend outward up to 175 miles (280 km) primarily to the east of the center. Saildrone (1069) located well
north-northeast of the center of Philippe has reported a peak one-minute wind of 40 mph (65 km/h) and a gust to 48 mph (78 km/h) within the past few hours.
>>> Central Tropical Atlantic…
Showers and thunderstorms have changed little in organization in association with an area of low pressure located roughly halfway between the Cabo Verde Islands and the Lesser Antilles.
Environmental conditions are forecast to be conducive for development, as long as this system remains far enough removed from Tropical Storm Philippe to its west.
A tropical depression or storm is expected to form in the next day or so while the system moves northwestward across the central tropical Atlantic.
