Increased Potential for Showers Through Sunday

A tropical wave moving across the Caribbean Sea may increase the potential for shower development across the Caribbean waters, and over portions of the Virgin Islands tonight and into Sunday. Rainfall accumulations should be on the light side. Today’s high temperatures should reach into the upper 80s with east to southeast winds at 15-20 miles per hour with higher gusts. By late Sunday into Monday, a dry air mass, inclusive of Saharan dust, is forecast to filter into the region and limit shower development during the afternoon.

Across the regional waters, mariners can expect seas to five feet and winds of 15 to 20 knots (17-23 miles per hour). Seas are forecast to increase to six feet later today and small craft operators should exercise caution when plying the Caribbean waters.  A moderate risk of rip currents exists for most beaches on St. Croix.

IN THE TROPICS
Shower activity in association with a tropical wave has become slightly more organized during the
past several hours. The wave sits midway between the Cape Verde Islands and the Windward Islands. Development of the wave is expected to be slow to occur during the next few days while the system moves westward at 15-20 miles per hour. Environmental conditions are forecast to become unfavorable for
development by early next week.
