The National Weather Service extended a flash flood warning for St. Thomas through 2 p.m. on Tuesday as thunderstorms dumped between two and three inches of rain across the island, with additional rainfall expected to complicate the afternoon commute.
The extended warning means St. Thomas residents face life-threatening flooding conditions in creeks, streams, urban areas, highways and underpasses through the early afternoon hours. Drivers should exercise extreme caution and avoid flooded roadways during peak commute times.
As of midday Tuesday, Doppler radar indicated thunderstorms were actively producing heavy rainfall across St. Thomas. Weather officials said one to two additional inches of rain could fall in the warned area before conditions improve. Flash flooding was already ongoing in some locations, with more expected to develop as the storm system persisted.
The Virgin Islands Department of Public Works, which maintains the territory’s road and drainage infrastructure, oversees stormwater management systems designed to handle heavy rainfall events. During acute weather conditions like flash flooding, residents are urged to report road hazards and blocked drainage to the department through official channels.
St. Thomas residents should take several precautions during the warning period. Never drive through flooded roadways, even if water appears shallow. Floodwaters can sweep vehicles off roads with surprising speed and force. Plan extra travel time if commuting is necessary, and consider delaying non-essential trips until conditions improve after 2 p.m.
The afternoon commute window presents particular risk. Heavy traffic combined with reduced visibility and water-covered roads creates dangerous conditions. Employers and employees should assess whether essential travel can be postponed until the warning lapses.
The Office of Disaster Recovery maintains resources for residents in the aftermath of severe weather. Those experiencing property damage or other disaster-related impacts should document conditions and contact the office at 340-774-0828 in St. Thomas or 340-773-1561 in St. Croix during business hours Monday through Friday, 8 a.m. to 5 p.m.
Residents should monitor updates from the National Weather Service in San Juan as the afternoon progresses. Conditions could change rapidly, and additional warnings may be issued if rainfall intensifies or flash flooding worsens in specific areas across St. Thomas.
