KEY MESSAGES

Issued at 126 PM AST Sat Jan 24 2026

* Hazardous marine and beach conditions continue, with dangerous offshore seas and rip currents posing a risk to small craft and swimmers.

* The risk of urban and small stream flooding will continue elevated, especially across western Puerto Rico through the rest of the afternoon hours.

* Across the U.S. Virgin Islands, passing showers will continue on and off for the rest of the day, with a drying trend expected on Sunday.

Short Term(This evening through Monday)

Issued at 126 PM AST Sat Jan 24 2026

Passing showers persisted across Puerto Rico and the U.S. Virgin Islands today. As of 1 PM, the Doppler estimated between a quarter to three quarters of an inch of rain between the USVI and eastern PR, and up to an inch over western PR. Maximum temperatures were in the mid-80s across the coastal areas of the islands to the mid-and upper 70s across the higher elevations. The wind was from the east between 10 and 20 mph.

A drier air mass will move over the region from this evening through early Monday morning. The precipitable water content is expected to fluctuate between 1.00-1.50 inches during the short- term period, with passing showers increasing once again on Monday. A building surface high pressure north-northeast of the region will continue to promote moderate to fresh (15-20 kt ) trades across the northeastern Caribbean. Therefore, breezy conditions with occasional passing showers can be expected through at least tonight. On Sunday, mostly sunny skies and fair weather conditions are expected to prevail.

Long Term(Tuesday through next Friday)

Issued at 426 AM AST Sat Jan 24 2026

Surface high over the eastern Atlantic will drive the trade winds from the east through Wednesday. At the mid and upper levels, a ridge builds, maintaining the mid levels very dry. Thus, fair weather is expected for most of the period. However, some showers may still reach the Virgin Islands and eastern Puerto Rico at times, while convection could still form in the west each afternoon. The risk of flooding will be very slim to none. By the end of the week, a polar trough will weaken the pressure gradient, with winds becoming very light on Thursday and Friday. A cold front will stall north of the area too. So far, it looks like the rain activity will stay along the Atlantic waters, so the chances or rain are not expected to be high on land areas. Also, winds will shift more from the south on Thursday and Friday. This will result in warmer temperatures, with 925 mb values at one to two standard deviations above normal.

AVIATION

(18Z TAFS) Issued at 126 PM AST Sat Jan 24 2026

Mainly VFR conds expected to prevail across all terminals. However, -SHRA will continue through at least tonight across the area terminals, causing brief MVFR conds. The 24/12z TJSJ sounding indicated east winds up to 26 kt blo 3000 ft.

MARINE

Issued at 126 PM AST Sat Jan 24 2026

A building surface high pressure from the western Atlantic into the central Atlantic will promote moderate to fresh trades through early next week. Lingering moisture from a distant surface trough will continue to promote passing showers through the rest of today, but the frequency of the showers will gradually decrease tonight. Choppy wind driven-seas up to 7 feet are expected mainly across the offshore Atlantic waters through late Sunday, and a Small Craft Advisory remains effect.

BEACH FORECAST

Issued at 126 PM AST Sat Jan 24 2026

Wind-driven seas will continue to promote a high risk of rip currents across the northern beaches of Puerto Rico through this evening. On Sunday, the risk of rip currents will be moderate for most north and east facing beaches in Puerto Rico, and across most of the Virgin Islands beaches.

SJU WATCHES/WARNINGS/ADVISORIES

PR...High Rip Current Risk until 6 PM AST this evening for PRZ001-002- 005-008.
