Aviation A tropical wave will move westward across the area
with associated convection mainly affecting the u.S. Virgin
islands this morning. Additional seabreeze convection will be
possible over puerto rico this afternoon with locally heavy
rainfall possible.VFR conditions will generally prevail outside
of thunderstorm activity.

Prev discussion issued issued by national weather service miami fl
short term...

deep tropical moisture remains in place across the region with
southeast wind flow. Precipitable water values will remain over 2
inches today. A weak tropical wave will move over the islands today
through the afternoon on Tuesday increasing the rain chances.

Heat index values will be near 100 for the next few days, bringing
hot and sticky weather to the area. This will make recovery
efforts difficult and overall living unpleasant as electricity
remains out across the island.

Long term...

relatively drier conditions are expected by late Tuesday as a sal
layer will move into the area precipitable water values drop below 2
inches. This will decrease the pops for the middle part of the week.

Flow will be easterly and pops will be around climatological normals
for the weekend.

Marine...

southeast winds will continue through Monday night. Scattered
showers and thunderstorms will move in from the east today. Winds
will increase around and showers and thunderstorms that do
develop. Tuesday winds will be more easterly.

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.
