Stay alert and be prepared to take shelter if storms develop. .Excessive Rainfall...Flooding in urban areas, roads, small streams, and washes, particularly across PR, Vieques, and Culebra. There is a low chance of isolated flash floods. Elsewhere, plan for water ponding on roads and in poorly drained areas. .Excessive Heat...This level of heat affects primarily those individuals extremely sensitive to heat, especially when outdoors without effective cooling and/or adequate hydration. These conditions are most likely across coastal and urban areas of PR. .Marine Conditions...Hazardous conditions for small craft in areas with seas of 7 feet or higher, particularly across Offshore Atlantic waters. Small craft should exercise caution elsewhere across the local waters. .Rip Currents...Life-threatening rip currents are possible in the surf zone, particularly across northern and eastern PR, Culebra, and eastern Vieques. Isolated stronger rip currents may occur elsewhere, especially near piers, jetties, and channels. .DAYS TWO THROUGH SEVEN...Sunday through Friday Excessive rainfall expected through the weekend and into early next week, as a vigorous tropical wave increases the potential for showers and thunderstorms, thereby raising the risk of flooding. Breezy to locally windy conditions will contribute to choppy seas and maintain a moderate rip current risk through most of the period. A Saharan Air Layer with minor to moderate concentrations of Saharan dust will bring hazy skies and drier air early next week. .SPOTTER INFORMATION STATEMENT... Spotter activation is encouraged. Please relay any information about flooding, winds, waves, and rip currents to the National Weather Service in San Juan. $$ AMZ716-726-VIZ001-002-030815- St. Thomas St. John adjacent Islands-St Croix- Nearshore Atlantic and adjacent Caribbean Coastal Waters- 414 AM AST Sat Aug 2 2025 This Hazardous Weather Outlook is for portions of USVI. .DAY ONE...Today and Tonight .Lightning...Isolated thunderstorms, particularly across the region.
