Weather Summary for the U.S. Virgin Islands
National Weather Service San Juan PR
539 PM AST FRI JUL 29 2016
Skies were mostly sunny except for some high clouds and local
streamers off the higher hills in the U.S. Virgin Islands today.
It was a little breezier than usual with sustained winds reaching
20 mph from time to time with gusts in the upper 20s. Temperatures
also reached at least 90 degrees on both islands this afternoon.
Although a few showers were observed forming over the area and
moving rapidly to the west northwest, no measurable rainfall was
observed at the airports today.
The atmosphere will slowly dry through Saturday noon as a
significant tropical wave advances toward the area from about 1100
miles east southeast of the area. Skies will be mostly sunny and
temperatures will again touch 90 degrees on the leeward coasts.
Breezy conditions will continue with winds becoming a little more
east northeast. The wave will begin to spread moisture and
increasing winds over the area Saturday evening with the most
intense winds, rainfall and thunderstorms becoming likely during
the morning on Sunday. Although it is still too early to
determine how much rain will fall on any given island during the
wave passage, a preliminary estimate is that some local urban and
gut flooding is likely and winds could easily gust to over 30 mph.
Some showers may continue overnight Sunday and into Monday.
Across the regional waters tonight...seas up to 6 feet and east
winds up to 20 knots are expected. There is a moderate risk of rip
currents for most of the beaches of St Croix and a few in Saint
Thomas and Saint John. Winds and seas will increase over the
weekend and small craft advisories will go into effect for the
Atlantic and outer Caribbean waters Saturday afternoon and night.
