Heavy rainfall associated with a developing trough system is expected to impact the British Virgin Islands beginning Monday night, bringing an increased risk of flash flooding through Wednesday, forecasters have warned.
The Antigua and Barbuda Meteorological Services on Sunday, April 12, 2026, warned of flash flood conditions, noting that the most significant impacts are likely between Tuesday and Wednesday.
Forecasters said rainfall totals of between three and five inches are anticipated across the islands, with locally higher amounts of up to seven inches possible within short periods.
Low-lying areas, small creeks and locations with poor drainage are expected to be most vulnerable. The advisory also warned of hazardous travel conditions, noting that roadways could become rapidly inundated during periods of intense rainfall.
The Antigua and Barbuda Meteorological Services urged residents to monitor updates and take precautionary measures ahead of the system.
“Monitor future forecasts and updates, clear debris from storm drains and gutters, and review your flash flood safety plan,” the agency said. “Be prepared to move to higher ground if a flash flood warning is issued.”
Officials said conditions will continue to be monitored as the system develops, and residents are encouraged to follow local forecasts for further guidance.
