.SHORT TERM...
A persistent southeast flow, at the surface, will remain in the
area through the middle of next week. But, the next chance for
organized rainfall will not be until late tomorrow for the USVI
and Monday for Puerto Rico when an impulse in the easterlies
makes it to the islands. Average rainfall with this disturbance
could be around 1 inch for most places.

Otherwise, heat index values will be around 100 degrees for the
next few days which will make circumstances on the islands,
miserable.

.LONG TERM...
Easterly flow conditions and upper level ridging return to the
area late Tuesday which will allow for more seasonable climate
expectations.

&&

.AVIATION...
Winds are gradually backing around to ESE and slowly weakening.
Still sufficient moisture exists for scattered showers and isolated
thunderstorms, with greatest coverage along the high terrain and the
windward side of Puerto Rico. Not enough coverage expected near
terminals to indicate restrictions, with generally VFR conditions
expected away from the convection.

&&

.MARINE...
Southeast winds will continue through Monday before becoming more
easterly Tuesday. Showers and scattered thunderstorms with heavy
rain and locally higher wind gusts and waves are possible through
this weekend.
