A flood watch will remain in effect across the U.S. Virgin Islands from Monday morning through Wednesday morning as a weather system moves toward the territory, bringing the potential for significant rainfall and dangerous flooding conditions.
The National Weather Service has identified elevated risk of flooding in poor drainage areas and urban neighborhoods across St. Thomas, St. John, St. Croix and Water Island. Low-water crossings could become impassable, while residents in areas with steep terrain face the additional threat of rapid river rises and landslides.
Heaviest Rain Expected Monday Night Into Tuesday
A trough system approaching from the northwest will trigger increasing shower and thunderstorm activity beginning Monday, with the most intense precipitation anticipated Monday night through Tuesday. Forecasters cite medium confidence in the forecast based on current atmospheric models and available data.
The timing and intensity of the system make the coming 48 hours a critical window for residents to prepare. Properties situated in flood-prone locations, including low-lying neighborhoods and areas near drainage systems, require particular attention.
What Residents Should Do Now
Those living in flood-risk zones should review evacuation routes and ensure emergency supplies are accessible. Drivers should avoid crossing flooded roads, as water depth can be deceiving and vehicles can be swept away in moving water. Even small amounts of flowing water can knock a person off their feet or disable a car.
Residents with property in steep terrain should monitor weather updates closely for landslide warnings. Heavy rainfall can destabilize slopes and trigger soil movement without warning.
Preparedness Resources
The Virgin Islands Department of Planning and Natural Resources maintains flood plain information and advisory maps available to the public. These resources help property owners understand their vulnerability and plan accordingly. The Department of Public Works manages storm drainage and can provide guidance on local drainage concerns.
Those seeking additional flood safety information can consult the National Weather Service safety resources at weather.gov/safety/flood.
Looking Ahead
Wednesday morning will mark the end of the active weather window, though residents should remain prepared for any lingering impacts. Following the system’s passage, conditions are expected to gradually improve.
Staying informed through official weather updates and heeding forecaster warnings will be essential for keeping families and property safe during the next three days.
