.SYNOPSIS...Tonight, expect passing showers mainly affecting the
eastern portions of Puerto Rico and adjacent islands. Thursday
and Friday are expected to be the windiest days. These winds will
continue to result in hazardous marine conditions, as well as
life- threatening rip currents across beaches of northern Puerto
Rico, from Aguadilla to Fajardo, Culebra, and the U.S. Virgin
Islands. Small Craft Advisories and a High Rip Current Risk will
remain in effect.

.SHORT TERM...Tonight through Thursday...

The meteorological network detected breezy to locally windy east-to-
east-southeast wind gusts; the maximum wind gusts were located south
of St Thomas, at Buck Island, with a maximum of around 43 mph.
Generally, the maximum wind gust observations range between 25 and
37 mph across Puerto Rico and the US Virgin Islands. Occasional
showers reached the islands throughout the day, mainly across the
local waters, moving inland across the windward locations. Showers
were induced during the afternoon across PR`s northwest quadrant due
to sea breeze variations and local effects. Maximum values in the
low 90s were observed across St Croix and northwest PR.

Model guidance and observations indicate increasing winds throughout
the end of the workweek, peaking around Thursday, as the surface
high pressure builds across the Central Atlantic, tightening the
local pressure gradient and promoting breezy to windy conditions.
Thus, there is a moderate/high chance of issuing a Wind Advisory for
the islands on Thursday. Showers embedded in the trades will bring
moderate to locally heavy rains across the islands. However,
tomorrow, Wednesday, is the wettest day of the short term.
Additionally, one or two thunderstorms will develop across PR`s
interior and western sections during the afternoon.

Life-threatening rip currents will form each day along the local
beaches, where residents and visitors are encouraged to heed the
advice of lifeguards and beach patrols. Therefore, a high rip
current risk is in effect for PR and the USVI`s east and north-
facing beaches.

.AVIATION...
(18Z TAFs)

VFR conditions are expected to be present mainly across the forecast
period. However, periods of +SHRA/SHRA will occasionally impact the
local terminals, mainly due to the easterly winds. An isolated TSRA
will develop near JBQ through this evening (01/23z). Winds will
remain mainly from the E to ESE at 15-25 kt, with gusts between 25
and 35 knots. Winds from the ESE will be around 10 to 15 knots after
01/13z overnight, but will increase again tomorrow aft 02/13z.


&&

.MARINE...

A surface high pressure over the Atlantic basin will continue to
promote fresh to locally strong easterly winds throughout the week.
Although winds are expected to increase on Wednesday...Thursday
and Friday are expected to be the windiest days of the week. Seas
will continue to build between 7 and 10 feet, and occasionally
higher, across the regional waters. As a result, hazardous choppy
seas are anticipated for most waters through the whole forecast
period. Showers and isolated thunderstorm activity will continue
for the next few days.


&&

.BEACH FORECAST...
Prevailing hazardous beach conditions are expected this week,
with Thursday and Friday seeing the highest risk, as they are
anticipated to be the windiest days this forecast period. This
will result increasing rough and dangerous seas, creating life-
threatening rip currents across beaches of northern Puerto Rico,
from Aguadilla to Fajardo, Culebra, and the U.S. Virgin Islands. A
High Rip Current Risk will remain in effect at least through
Saturday afternoon.

Strong rip current will continue to affect all local beaches, and
swimmers are urged to exercise caution by staying near
lifeguards, avoiding dangerous waters, and following warning
signs. If caught in a rip current, remain calm, swim parallel to
shore to escape, or float and signal for help if needed.
