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 generallyVFR 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.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
