Stay alert and be prepared to take shelter if storms develop. .Excessive Rainfall...Flooding in urban areas, roads, small streams, and washes, particularly across lightning-risk areas. 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 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. .Rip Currents...Life-threatening rip currents are possible in the surf zone, particularly across northern and eastern beaches of Puerto Rico and Culebra. Isolated stronger rip currents may occur elsewhere, especially near piers, jetties, and channels. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday Daily afternoon thunderstorms will bring a limited to elevated risk of flooding and dangerous lightning, mainly across central, western, and northern Puerto Rico. Mid to late week, an approaching frontal boundary and pre-frontal trough will increase moisture and instability, leading to more widespread and longer- lasting thunderstorms and a higher flood and lightning threat. Elevated heat impacts will persist through the workweek and continue into the weekend and early next week. A moderate rip current risk remains along northern and eastern beaches, but long- period northerly swells arriving this weekend will create hazardous to potentially life-threatening surf and rip currents. Increasing winds will further worsen marine and coastal conditions and may also pose wind hazards along exposed coastal areas this weekend. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed. $$ AMZ716-726-VIZ001-002-151000- St. Thomas St. John adjacent Islands-St Croix- Nearshore Atlantic and adjacent Caribbean Coastal Waters- 511 AM AST Tue Oct 14 2025 This Hazardous Weather Outlook is for portions of USVI. .DAY ONE...Tonight .Excessive Heat...This level of heat affects most individuals sensitive to heat, especially those without effective cooling and/or adequate hydration.
