Meteorological authorities are advising residents across the Lesser Antilles to prepare for significant weather developments unfolding through Thursday. A pronounced trough system is introducing elevated moisture levels and atmospheric instability throughout the region, creating conditions ripe for substantial precipitation.
The immediate forecast indicates persistent cloud cover progressing to fully overcast skies, accompanied by widespread scattered showers. Meteorological models suggest these showers will intermittently intensify into isolated thunderstorms, particularly during evening and overnight hours. Officials have issued specific alerts for communities in topographically vulnerable zones, highlighting imminent risks of flash flooding, landslides, and dislodged rocks. Residents in these areas are urged to maintain heightened awareness and implement precautionary measures. A formal flood watch remains under consideration for overnight implementation.
Compounding the situation, a moderate concentration of Saharan dust particles is projected to traverse the island territories overnight. Health specialists advise individuals with pre-existing respiratory conditions, including asthma and allergies, to minimize outdoor exposure and consider protective measures due to anticipated reductions in air quality.
Maritime conditions present additional concerns, particularly for vessel operators. While western coastal waters will experience relatively manageable wave heights not exceeding three feet, eastern sectors face dramatically different conditions. Swells along eastern coastlines are forecast to build to approximately eight feet during afternoon hours, with further intensification expected overnight. Projections indicate waves may approach ten feet by Thursday morning, prompting the immediate activation of a Small Craft Advisory. This advisory will escalate to a full marine warning starting Thursday morning, indicating hazardous seafaring conditions. All maritime users, including fishermen and recreational boaters, are strongly advised to continuously monitor maritime updates and exercise extreme caution, with particular emphasis on avoiding eastern coastal waters.
