A few isolated showers are expected to move over the local area until a dry Saharan mass enters the region from the east later this afternoon. This drier air will limit shower activity and promote a tranquil weather regime through Tuesday. Daytime high temperatures are expected to range between the middle 80s and low 90s.
Across the local waters, five foot seas and winds out of the east at 15-20 knots (17-23 miles per hour) are forecast. Small craft operators are advised to exercise caution. There is a moderate risk of rip currents for the northern beaches of the Virgin Islands.
IN THE TROPICS
At 5 a.m., Tropical Storm Dorian was located about 555 miles east-southeast of Barbados or some 996 miles southeast of St. Croix. Dorian has top winds of 40 miles per hour and is tracking to the west at 13 miles per hour. Tropical storm force winds (winds between 37-73 miles per hour) extend 25 miles from the center. The storm has rainfall potential of 2-4 inches. Dorian’s ability to develop is being challenged by the presence of both dry air and wind shear. The National Hurricane Center has adjusted the projected path of the storm system more to the southwest which is further away from the major land areas of the Caribbean.
On its present track, the center of Dorian should pass 121 miles to the southwest of St. Croix on Wednesday at 1 p.m. At that time, Dorian is forecast to be a tropical storm with top winds of 70 miles per hour. No wind impact is expected in the Virgin Islands.
