region for the next several days. Areas of low level moisture
embedded in the east northeast trades will continue to move across
the region for the next several days inducing brief periods of
passing showers across the local islands.
SHORT TERM...Tonight through Saturday...
The remnants of a frontal boundary are located across the Atlantic
waters just to the north of Puerto Rico and the U.S. Virgin
Islands. Latest satellites images depicted a layer of low to mid
level clouds across the region, producing variable to mostly
cloudy skies across the local islands. However, terminal Doppler
radar detected only brief passing showers in association with
this cloudiness. Under a northeast low level wind flow, quick
passing showers are possible across the U.S. Virgin Islands,
Vieques, Culebra as well as across the eastern and northern
sections of Puerto Rico tonight and Friday morning. Some shower
activity is also expected to develop across western and interior
sections of Puerto Rico Friday afternoon. On Saturday, small
patches of low level moisture associated with the frontal remnants
to our north will result in an increase in trade wind shower
activity over portions of the local islands.
LONG TERM...Sunday through Friday...From previous discussion...
Strong surface high pressure across the north western Atlantic
will move eastward as a low pressure and associated cold front
exit the U.S. east coast by mid week. This will induce a moderate
to fresh trade winds across the region during the forecast period.
These winds will transport patches of low level moisture to the
local area. At this time, no significant weather events are
forecast to affect the region in the long term.
AVIATION...BKN-OVC cld layer across the region with FEW -SHRA
en route mainly btw PR and the nrn Leeward Islands...but overall VFR
durg entire prd at all terminals and across flying area. Cld lyrs

MARINE...Seas slowly subsided across portions of the local
waters early today, but will increase once again tonight as
another pulse of a northerly swell will arrive and spread across
the Atlantic waters and local passages through at least Friday.
The northeasterly swell along with choppy wind driven seas will
generate hazardous sea conditions for the next several days. Seas
will therefore remain hazardous for the rest of the week an into
the weekend.
Dangerous surf conditions with moderate to high risk of rip currents
will continue for most of the local beaches though Friday. Please
refer to the latest Surf Zone Forecast issued by the WFO San Juan
PR for update and additional info.
