Stay alert and be prepared to take shelter if storms develop. .Excessive Rainfall...Ponding of water in roads and poorly drained areas, particularly across western/southwestern sections. There is a low chance of localized urban and small streams flooding. .Excessive Heat...This level of heat affects most individuals sensitive to heat, especially those without effective cooling and/or adequate hydration. Those extremely sensitive to heat face the highest risk. Some health systems and heat-sensitive industries could be affected. These conditions are most likely across urban and coastal areas. During the peak hours of the day, heat indexes are very likely to exceed 100 degrees Fahrenheit and meet Heat Advisory Criteria for a short time period. Although Heat Advisories are not in effect, we`ll keep monitoring the conditions throughout the day and update the forecast if any changes are introduced. .Wind...Breezy to Windy conditions (23-33 kts | 26-38 mph), with the greatest risk across coastal areas. Outdoor items could blow around or be damaged. .Marine Conditions...Hazardous conditions for small craft in areas with seas of 7 feet or higher, particularly across most regional waters and local passages. Small craft should exercise caution elsewhere across the local waters. .Rip Currents...Life-threatening rip currents are possible in the surf zone, particularly across most beaches of the island, including Vieques and Culebra. Isolated stronger rip currents may occur elsewhere, especially near piers, jetties, and channels. .DAYS TWO THROUGH SEVEN...Friday through Wednesday Tropical waves are still expected to approach the region, pooling high moisture content, enhancing shower and thunderstorm activity, and elevating flooding potential. Limited to elevated heating risk is likely to persist for the next several days. Moderate to fresh trade winds will continue promoting choppy seas across the regional waters and local passages for the next few days, small craft must exercise caution. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed. $$ AMZ716-726-VIZ001-002-250900- St. Thomas St. John adjacent Islands-St Croix- Nearshore Atlantic and adjacent Caribbean Coastal Waters- 454 AM AST Thu Jul 24 2025 This Hazardous Weather Outlook is for portions of USVI. .DAY ONE...Today and Tonight .Excessive Heat...This level of heat affects primarily those individuals extremely sensitive to heat, especially when outdoors without effective cooling and/or adequate hydration.
