AVIATION

(18Z TAFS) Issued at 143 PM AST Fri Jul 24 2026

VFR conditions will persist across all TAF sites during the period. HZ will continue to result in limited VIS at least until 25/10Z for eastern-located sites and then for the rest of the sites. VCSH and -VCTS are possible from 24/19Z to 24/21Z near the vicinity of TJBQ, and after that at 25/06Z across TIST & TISX. Winds will continue from the E at 15 knots and gusty winds up to 25 knots, decreasing at 24/23Z and increasing again at 25/13Z from the E.

MARINE

Issued at 143 PM AST Fri Jul 24 2026

A broad surface high pressure will maintain moderate to locally fresh east-southeast winds through at least Saturday, becoming moderate on Sunday. Moderate to high concentrations of Saharan dust will continue to spread across the region for the rest of today, slightly reducing visibility, diminishing on Saturday. Shower activity should gradually increase this afternoon as a weak tropical wave moves across the region. A vigorous tropical wave is expected to reach the northeastern Caribbean from late Sunday into Monday, increasing moisture and the potential for thunderstorm activity over the local Caribbean waters, which will result in localized hazardous marine conditions.

BEACH FORECAST

Issued at 143 PM AST Fri Jul 24 2026

The beach forecast remains on track. The moderate risk of rip currents continues across northern and eastern beaches of Puerto Rico, including Vieques and Culebra, and St. Croix in the U.S. Virgin Islands, with low risk elsewhere. Although there is a moderate risk, beachgoers must exercise caution as life-threatening rip currents remain possible along the surf zone. As winds weaken by Sunday, the risk may be lowered in some areas, though beachgoers must remain aware of isolated life-threatening rip currents in the vicinity of groins, jetties, reefs, and piers. As winds gradually strengthen, the moderate risk should spread across the islands and persist for the rest of the forecast period. Besides rip currents, beachgoers should continue to monitor weather conditions, as afternoon showers and isolated thunderstorms may move near coastal areas of western Puerto Rico, including eastern Puerto Rico on Sunday and Monday. In addition, moderate to high concentrations will linger across the region through Saturday, deteriorating air quality.

FIRE WEATHER

Issued at 143 PM AST Fri Jul 24 2026

Surface conditions remained on the drier side as a drier airmass dominated the region resulting in RH values dropping into the low 50s across stations along the southern coastal plains. For tomorrow surface winds will remain from the east peaking up at around 10 AM AST up to 15 knots and slightly high in localized areas. RH values for tomorrow will range between the mid 50s to upper 60s due to some moisture associated with the previous tropical wave.
