Low-level moisture associated with a cold front will linger across the region though Monday which will support the development of occasional passing showers. As the showers are fast-moving, rainfall accumulation will be minimal. Additional trade wind showers are expected as winds become more east to southeast by Monday. Winds are forecast to decrease later tonight through Tuesday as an Atlantic high pressure shifts slightly northeast of the region. Winds will also become more southeasterly by Tuesday and Wednesday which will lead to warmer than normal temperatures.
Marine conditions are continuing to deteriorate due to the combination of breezy conditions and a northerly swell. Hazardous marine conditions are forecast as wave heights increase. The high winds and northerly swell will last through Tuesday night into Wednesday. Occasional passing showers with gusty winds are expected to move across the regional waters during the next several days.
A Small Craft Advisory, High Surf Advisory, and Coastal Flood Advisory are in effect, and there is a high risk of rip currents for all Virgin Islands beaches through Monday evening.
