Area Forecast Discussion
National Weather Service San Juan PR
1046 AM AST Mon Mar 15 2021

.UPDATE...A surface high pressure over the southwestern Atlantic
is promoting northerly wind flow across the region. Embedded in
this flow are fragments of an old frontal boundary, that resulted
in scattered showers along our coastal Atlantic waters and
northern municipalities of Puerto Rico through the morning hours.
For the rest of the day, low level moisture will continue to
stream southwards across the islands, and aid in the development
of afternoon showers over portions of central and southern PR and
from streamers developing off the U.S. Virgin Islands. Rainfall
accumulations should be light to moderate due to the mid level
ridge promoting drier air and stable conditions aloft.

&&

.AVIATION...Mainly VFR conditions expected across all terminals.
However, SHRA in and around TJPS may cause MVFR conds btw 16z-22z.
The 15/12z TJSJ sounding indicated NE winds at less than 10 kts
below 3000 ft.

&&

.MARINE...Coastal buoys were indicating seas between 2-4 feet and
NE winds around 10 kts. Relative tranquil marine conditions will
continue through the rest of the day. However, hazardous seas are
expected to build quickly from late Tuesday night through
Wednesday, as a long period northerly swell fills in across the
Atlantic waters. Seas are currently forecast to increase up to 10
feet across the Atlantic waters. This swell will cause life
threatening rip currents and high surf conditions from the
northwest to northeast coasts of PR, Culebra and the northern
USVI. Trade winds are expected to increase tonight from the east
to northeast between 15-20 kts.

&&

.PREV DISCUSSION... /issued 456 AM AST Mon Mar 15 2021/

SYNOPSIS... A light to moderate north northeast wind flow will
prevail as a strong surface high pressure ridge will build across
the southwest Atlantic and north of the region during the next few
days. A mid-level ridge will strengthen across the region resulting
in increasing stability aloft. Shallow moisture carried by the
prevailing northerly winds will move across the region and result
in periods of passing clouds and showers. This will affect portions
of the north and east coastal areas of the islands during the mornings,
followed by locally and diurnally induced afternoon showers. A gradual
drying trend is anticipated by mid week as a high pressure system
will establish and remain the dominant feature. Another surge of
moisture is however forecast by the latter part of the week, resulting
in more frequent passing showers. A northerly swell is also expected
to invade the local waters by late Tuesday night.

SHORT TERM...Today through Wednesday...

A mid to upper level ridge and the associated surface high pressure
will dominate the region for the next several days as the ridge
moves eastward today, fragments of moisture embedded in the
northeasterly winds will maintain the potential for some passing
showers over the local region. According to GOES-16, precipitable
water values today are fluctuating between 0.90 to 1.1 inches over
the forecast area. Additionally, the surface ridge will also gradually
tighten the pressure gradient, causing winds to around 20 mph over
the local waters and cooler temperatures over the region for the
next several days. On Tuesday, mainly fair weather conditions will
prevail over the region as a drier airmass filter into the region.
In combination with stable conditions aloft, this will result in
clear to partly cloudy skies in the morning hours and mostly sunny
with a few passing showers in the afternoon hours, mainly over
western sections of Puerto Rico, due to the local effects. In
general, Tuesday will be the driest day of the short-term forecast.

On Wednesday, the pattern changes as the surface high pressure
enters the central Atlantic and pushes moisture remnants from an
old frontal boundary across the region. This additional moisture
will increase the potential for shower activity, mainly in the
afternoon hours due to the local effects. The expected shower
activity at this moment should not be significant due to the
stable conditions aloft. Therefore, only ponding of water in
roadways and poor drainage areas will be possible with the
heaviest activity.

LONG TERM...Thursday through Monday...

The first half of the long term period starts with a drying trend
once again, as low level moisture will erode and the mid to upper
level ridge and associated surface high pressure will dominate
local weather pattern along with a drier air mass. So far model
guidance continued to suggest precipitable water values between
0.90 to 1.2 inches through Friday, as the surface ridge moves
further eastward and winds become more northeast to east. This
wind flow will however aid in bringing periods of passing showers
to the coastal areas during the overnight and early morning hours,
followed by some afternoon shower activity which should be focused
over the west and southwestern portions of Puerto Rico each afternoon.
Limited or no significant shower activity forecast elsewhere.

On Saturday and into Sunday, as the high surface pressure moves
into the east and central Atlantic, patches of moisture will
continue to filter the area but will be less frequent as the
local pressure gradient will loosen and winds will veer becoming
more east southeast while diminishing. Consequently, some weak
troughiness will establish across the area thereafter and bring a
gradual increase in low level moisture, as well as warmer daytime
temperatures. From Sunday onwards moisture convergence increases
once again, as a cold front will move into the west Atlantic and
stall northwest of the area. As a result, this would be the best
chance for early morning showers and enhanced afternoon convection
over portions of the islands but mainly the west and northwest
sections of Puerto Rico. The potential for urban and small stream
flooding will therefore increase Sunday through Monday as a somewhat
wetter pattern is expected so far.

AVIATION...Mainly VFR conditions thru period. Sfc winds fm NNE 10-15
kts with occasional gusts. Some vcsh could be possibles over TISX,
TIST and TJSJ mostly between 15/12Z to 15/18Z. Sfc Wnd will
diminish to 10 kts or VRB aft sunset 15/22Z. No significant
operational wx impacts attm.

MARINE...
Mariners can expect improving conditions over the Atlantic waters
for the day or so, however, small craft operators should exercise
caution due to seas between 4 and 6 feet and winds between 15 and
20 knots. Elsewhere, seas will continue at 5 feet or less and
winds between 10 and 15 knots. Another northerly swell and increasing
winds is forecast by late Tuesday night. Therefore deteriorating
marine and coastal conditions will again be likely.

Beachgoers, the risk of rip currents is moderate for the north-
facing beaches of Puerto Rico, St Thomas and Culebra today.
