.Short Term(This afternoon through Sunday)...
Issued at 120 PM AST Fri Jan 23 2026

Mostly cloudy skies were observed across the islands as showers
increased throughout the day. The Doppler radar estimated up to
half an inch of rain in portions of southeastern Puerto Rico.
Additional showers were developing around noon over southwestern
PR and downwind of the USVI. High temperatures were in the mid-80s
across most coastal areas. The wind was from the east between 12
and 18 mph.

A broad area of higher than normal precipitable water (PWAT)
content of 1.70-1.90 inches, currently to the east and south of
the Leeward Islands will continue to stream over local area
through at least Saturday. A brief weakness in the pressure
gradient will promote mostly moderate trades (around 15 kt) during
the same period. Therefore, an overall wet pattern is expected to
prevail with frequent passing showers over the USVI and the
eastern half of PR, where rainfall accumulations could range from
half to an inch of rain, enough to cause minor flooding concerns
along roads and other poor drainage areas. Also, as winds ease
somewhat, better organized shallow convection is expected to
develop this afternoon and once again on Saturday afternoon over
portions of the Cordillera and western PR. On Sunday, the arrival
of a drier air mass with PWAT dropping to near 1.25 inches and
stronger trades (15-20kt) will promote mostly fair weather
conditions across all the islands in general.

steer patches of drier and moist air towards the islands,
resulting in in seasonal (
