A regional flash flood watch is currently active across six Eastern Caribbean island nations, including Antigua and Barbuda, as post-tropical storm moisture brings the threat of dangerous flash flooding to vulnerable coastal and low-lying zones through midday Sunday.
The official alert was issued by the Antigua and Barbuda Meteorological Services at 7:34 p.m. local time on Saturday, covering not just the twin-island nation but also neighboring Montserrat, St. Kitts, Nevis and Anguilla. The watch will remain in place until 12 p.m. August 30, with meteorologists continuing to track the weather system’s progression across the region.
Forecasters confirm that the unsettled weather pattern driving this event is directly linked to the lingering remnants of Tropical Storm Dolly. The system is projected to push consistent heavy rainfall across the affected area through Sunday, with projected total accumulations ranging between 2 and 5 inches across most zones. In localized pockets, short intense downpours could push rainfall totals even higher, significantly amplifying the risk of sudden flash flooding.
Meteorological officials have highlighted the specific risks facing communities in the warning zone. Low-lying neighborhoods that are already prone to routine flooding face the greatest threat of inundation, while key regional roadways may also become impassable. Additionally, heavy rain is expected to cut visibility for motorists, creating hazardous driving conditions across the watch area through Sunday morning.
Local authorities have issued clear guidance for residents across all affected islands. The public is urged to stay updated on changing weather conditions, revisit and confirm their personal flash flood emergency response plans, and stand by to evacuate to higher ground immediately if flooding begins or a more urgent flash flood warning is issued. The Antigua and Barbuda Meteorological Services has committed to ongoing monitoring of the system, with regular updates to be released to the public as new weather data becomes available.
