986 FXCA62 TJSJ 251858 AFDSJU Area Forecast Discussion National Weather Service San Juan PR 258 PM AST Sun Jan 25 2026 ...New SHORT TERM, AVIATION, MARINE... .KEY MESSAGES... Issued at 108 PM AST Sun Jan 25 2026 * Choppy, wind-driven seas will continue through Monday. * Breezy conditions will continue for the rest of the day. Showers will increase the potential to observe minor flooding on Monday. * Across the U.S. Virgin Islands, fair weather conditions are expected tonight. Passing showers increasing on Monday. && .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. && .SJU WATCHES/WARNINGS/ADVISORIES... PR...None. VI...None. AM...Small Craft Advisory until 6 PM AST this evening for AMZ711. && $$ SHORT TERM/MARINE...DSR LONG TERM/BEACH...ERG AVIATION...DSR
