WEATHER (6:00 AM on 21 December 2025): A lower-level trough is affecting the area (craft advisory still in effect)

Meteorological authorities have issued critical advisories for residents and maritime operators across the Caribbean region as an active weather system moves through the area. A low-pressure trough continues to generate unstable atmospheric conditions, presenting a multifaceted weather challenge combining precipitation risks with hazardous marine conditions.

The terrestrial forecast indicates predominantly overcast skies throughout the day with intermittent scattered showers, particularly during morning hours. Meteorological models project a gradual diminishment of precipitation activity as the day progresses toward afternoon hours, though isolated showers may persist. Officials have specifically alerted communities in geologically vulnerable zones, including areas susceptible to landslides and falling rocks, to maintain heightened awareness and implement appropriate precautionary measures.

Maritime conditions present additional concerns, with moderate sea states expected across the region. Significant wave height differentials are anticipated between coastlines, with western exposures experiencing approximately 5-foot waves accompanied by northerly swells, while eastern facing coastlines may encounter more substantial 8-foot waves. In response to these conditions, maritime authorities have implemented a dual advisory system: A Small Craft Advisory remains active primarily for eastern coastal waters, while a High Surf Advisory has been enacted for western and northern coastal areas. These warnings specifically urge heightened vigilance among operators of smaller vessels and recreational sea bathers.

Coastal improvement is projected to commence after nightfall along western exposures, with meteorological monitoring stations continuing to track system evolution. Tonight’s forecast suggests a transition to partly cloudy conditions with occasional cloud cover and potential isolated showers during late-night hours.
