Earl is moving toward the northwest near 3 mph (6 km/h). A turn toward the north with some increase in forward speed is expected on Monday, followed by a turn toward the north-northeast later this week.
Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Slow strengthening is forecast over the next several days, and Earl could become a hurricane later this week.
Tropical-storm-force winds extend outward up to 105 miles (165 km) from the center.
NOAA data buoy 41043 recently reported a sustained wind of 40 mph (65 km/h) with a gust to 49 mph (80 km/h).
HAZARDS AFFECTING LAND
RAINFALL: Earl is expected to produce additional rainfall amounts of 1 to 4 inches, with isolated storm totals of 8 inches, across the Leeward Islands, U.S. and British Virgin Islands, and Puerto Rico through Monday.
Limited flash, urban, and small stream flooding impacts are possible. Rapid rises on rivers and mudslides in areas of steep terrain are also possible, especially across the central interior region of Puerto Rico. Locally considerable flood impacts are possible in areas that will receive heavier rainfall totals.
WIND: Gusty winds, especially in squalls, are possible across the northern Leeward Islands, the Virgin Islands, and Puerto Rico through tonight.
>>> Eastern Tropical Atlantic:
A tropical wave between the west coast of Africa and the Cabo Verde Islands is producing some disorganized shower and thunderstorm activity.
An area of low pressure could form in association with this system, and subsequent gradual development is possible as it moves generally west-northwestward over the eastern and central tropical Atlantic during the next several days.
