.Short Term(This evening through Tuesday)...
Issued at 108 PM AST Sun Jan 25 2026

Sunny to partly cloudy skies were observed across the islands
today. Passing showers were noted mainly across the regional
waters and eastern portions of Puerto Rico. Across the U.S. Virgin
Islands, streamers developed downwind of the islands, leaving
minor rainfall accumulations over land areas. Maximum temperatures
were in the mid-80s across the lower elevations of the islands.
The wind was from the east at 15 to 20 mph with gusts up to 30
mph.

For the rest of today, limited shower development is expected over
the islands, however, passing showers cannot be ruled out. Light
showers are still expected to develop over western PR this
afternoon. A building surface high pressure over the central
Atlantic will promote moderate trades early in the week. Embedded
in this winds, patches of moisture will arrive at times,
particularly during the daytime each day. This fluctuations in
moisture content will aid in the development of afternoon showers
over western PR, and downwind of the USVI and eastern PR. These
showers are expected to cause ponding of water along roads and
other poor drainage areas. Higher rainfall accumulations close to
an inch are expected in western PR.

.Long Term(Wednesday through next Saturday)...
Issued at 305 AM AST Sun Jan 25 2026

The mid to upper level ridge will hold on Wednesday. At the low
levels, limited moisture in anticipated, so fair weather should
persist until then. Then, there are some changes in store Thursday
onward. First, a polar trough will weaken the pressure gradient,
causing winds to become lighter. Surface steering flow will fall to
nearly 9 knots on Thursday to about 2-6 knots on Friday.  The polar
trough will escort a cold front near Hispaniola and Cuba, with winds
shifting from the south from the surface into the mid levels of the
atmosphere. As a result, warmer than normal temperatures are
anticipated. Also, the shift in winds will bring a slot of dry air
on Thursday, followed by increasing moisture Friday onward. With
light winds on Friday, showers are expected to form in the
Cordillera Central, where urban and small stream flooding could
occur. Then, on the weekend, additional moisture will approach
from the south, and also from the north (associated with the cold
front). Increasing shower frequency is expected for the Caribbean
and Atlantic waters. The proximity of the cold front will cause
winds to weaken again on Sunday, with speeds of 1 to 5 knots and
variable wind speeds. The global models also show the front
crossing late on Sunday, which could cause another increase in
showers and thunderstorms across the area.

.AVIATION...
(18Z TAFS)
Issued at 108 PM AST Sun Jan 25 2026

Mainly VFR conditions are expected to prevail across all terminals
during the next 24 hours. However, passing -SHRA could move at
times in and around TJSJ and the USVI. The 25/12z TJSJ sounding
indicated east winds up to 27 kt blo FL040.

.MARINE...
Issued at 108 PM AST Sun Jan 25 2026

A building surface high pressure over the western Atlantic will
continue to promote moderate to fresh trades through Monday.
Winds will remain moderate toward the middle portion of the week
as the high rolls into the central and eastern Atlantic. A Small
Craft Advisory is in effect for the offshore Atlantic waters
through 6 PM this afternoon due to seas up to 7 feet. Choppy
wind-driven seas up to 6 feet are expected across the rest of the
local waters through late Monday.

.BEACH FORECAST...
Issued at 108 PM AST Sun Jan 25 2026

Breezy conditions will maintain a moderate rip current risk for
the north and east facing beaches of Puerto Rico, as well as for
Vieques, Culebra and all the beaches across the Virgin Islands.
Similar conditions are expected to persist through the upcoming
days, with only the west, south, and southwest of Puerto Rico with
a low risk of rip currents.
