Area Forecast Discussion
National Weather Service San Juan PR
1038 AM AST Fri Dec 16 2022

...New UPDATE, AVIATION, MARINE...

.UPDATE...
Issued at 1025 AM AST Fri Dec 16 2022

The main concern remains marine and coastal conditions. Weather-
wise, generally fair weather is expected to prevail, with passing
showers possible from time to time. Today's sounding is drier than
yesterday, with gradual drying starting around 900 hPa, and more
drastic drying above around 800 to 700 hPa. These dry mid-levels
will inhibit convective development. Cannot rule out some showers
for the western and interior portions of Puerto Rico this afternoon,
but considering showers didn't really materialize yesterday, when
there was more available moisture, it seems more likely that little
to no shower activity will occur there. Some streamer activity is
also possible. Clouds have formed downwind of and over St. Croix,
much as they did yesterday, when there were a few brief showers over
the waters downwind of the island. It is unlikely that any streamer
development that does occur there will affect land.

&&

.SYNOPSIS...Hazardous seas and life-threatening rip currents will
continue through the weekend due to long period northerly swells.
The threat for flooding will remain low through next week, as the
region remains under the influence of a building upper level
ridge across the Caribbean Basin.

&&

.SHORT TERM...Today through Sunday...
The main feature in the short-term period is a ridge of high
pressure centered over the western Caribbean Sea that continues to
promote dry and stable conditions aloft, with a trade wind cap
inversion around 850 mb. This feature will persist through at least
Sunday, acting as a limiting factor for any strong rains. At the
surface, the winds have shifted from the east and is bringing
patches of enhanced moisture across the islands. This seasonal
advective pattern will persist with periods of passing showers along
eastern Puerto Rico and the United States Virgin Islands. In the
afternoon, some showers may fire up along the southwest, but again,
conditions aloft do not favor significant rainfall accumulations. A
similar pattern is expected today and tomorrow, when precipitable
water values will be around 1.2 to 1.4 inches, which is near
climatological values. However, by Sunday, values drop below 1.0
inch, and therefore, mainly fair weather will prevail with limited
shower activity and clear skies.

.LONG TERM...Monday through Friday...
An upper level ridge is expected to build over the Caribbean basin
during the next several days and hold through the end of the long
term period. Upper level troughs and associated fronts at the
surface will remain mainly north of the region. Therefore, this
weather pattern will continue to promote stable conditions and
drier air aloft, as well as limited vertical development of
showers that could develop in diurnal activity over the islands
each afternoon.

At the surface a high pressure will move slowly from the US East
Coast into the central Atlantic by the end of the long term
period. Then, by Friday a deep layered low over the Eastern
Seaboard and associated front over the western Atlantic will
promote southeasterly winds across the northeastern Caribbean. The
trade wind cap is forecast to relax somewhat, and allow better
pooling of moisture compared to previous days. Therefore, a slight
increase in shower activity is forecast for the end of the week into
the weekend.

Generally VFR conds expected across all aerodromes next 24 hours.
Afternoon SHRA poss in W/interior PR; if they occur, expected to
remain W of TJPS and S of TJBQ. Passing SHRA tonight over waters,
could affect USVI/E PR, with minimal impacts expected at terminals.
Winds E at 8 to 14 kts, diminishing after sunset, becoming generally
light overnight.

&&

.AVIATION...Mainly VFR conditions expected to prevail through the forecast
period. SHRA will move at times near TJSJ and the USVI terminals,
but significant impacts in operations are not expected. SHRA may
also develop after 17Z across SW PR, with mountain obscuration along
the Cordillera Central. Winds will be out of the east at 10 to 12
knots, with stronger gusts.

.MARINE...
Issued at 1025 AM AST Fri Dec 16 2022

Hazardous conditions continue. Seas of 7 to 8 feet will continue.
The San Juan buoy has shown seas of 6 to 7 feet through the morning.
Another swell pulse will help maintain these hazardous conditions
through the weekend, as well. High surf conditions are expected for
beaches exposed to the north and northeast across all islands. Small
Craft Advisories and High Surf Advisories remain in effect through
the weekend.

&&

.MARINE...Hazardous seas, dangerous breaking waves, and life-
threatening rip currents will continue through at least early next
week due to long period northerly swells. Small Craft Advisories,
as well as High Surf Advisories and a High Rip Current Risk
remain in effect for the Atlantic waters and passages, as well
along beaches with northern exposure. Refer to the latest Marine
Weather message (MWWSJU), Coastal Waters Forecast (CWFSJU) and
Coastal Hazard Message (CFWSJU) for detailed information.
