Synopsis Unstable conditions are expected through early
Thursday as a tropical wave is forecast to move across the local
region between Wednesday and Thursday increasing winds and showers
coverage across the local islands. After this wave moves away a
low and mid- level ridge will hold across the region with drier
air filtering in out of the east. This will limit shower and
thunderstorm development to the eastern, interior and western
portions of puerto rico during the afternoon.

Short term Showers have persisted across portions of the usvi
and across much of the eastern and northern half of puerto rico.

Around half an inch of rain was observed with the heaviest
showers. A mid level high pressure across the western atlantic
that extends into the northeastern caribbean will continue to
promote breezy east to northeast trades across the region during
the next few days. Somewhat cooler temperatures are expected under
the northeast wind flow.

An active tropical wave is currently moving across the leeward
islands and is forecast to cross the region through the evening
hours. An upper level low is forecast to linger today over
hispaniola while moving slowly westward, providing some divergence
aloft over the region. These two features will result in scattered
to numerous showers and thunderstorms through the evening hours
across the forecast area. This activity will result in urban and
small stream flooding.

Long term Saturday through Thursday.

A mid to upper-level ridge will hold across the region through
the long-term period with low level moisture periodically working
in from the east as well as drier air. As a result of limited
moisture and instability showers and thunderstorms developed will
be limited to the northern portion of puerto rico during the
morning hours, and southwest areas of puerto rico during the
afternoon. Below normal temperature are expected to prevail
through the weekend as winds will remain from the northeast. Winds
will shift to a more easterly component after Tuesday and
moisture is also expected to slightly increase.

Aviation Shra expected with approaching tropical wave today
across most of the terminals. Iso tsra possible across the
usvi eastern pr terminals through the morning hours. Afternoon
shra tsra mainly expected over the interior and southwestern
quadrant of pr. Tempo MVFR conds and mtn top obscd are expected with
shra today. Breezy ene winds between 15-25 kt expected to prevail.

Marine Seas will continue on the range of between 5 to 7 feet
and winds on the range of 15 to 20 knots with an occasional
stronger gusts. This pattern will generate choppy and hazardous
conditions therefore a small craft advisory is in effect for the
offshore atlantic waters and caribbean waters. Shower and
thunderstorm coverage is expected as a tropical wave moves across
the caribbean waters through Thursday morning.

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.
