Hazardous Weather Outlook National Weather Service San Juan PR 516 AM AST Fri Oct 17 2025 AMZ711>745-PRZ001>013-180930- San Juan and Vicinity-Northeast-Southeast-Eastern Interior- North Central-Central Interior-Ponce and Vicinity-Northwest- Western Interior-Mayaguez and Vicinity-Southwest-Culebra-Vieques- The nearshore and off shore Atlantic and Caribbean Coastal Waters- 516 AM AST Fri Oct 17 2025 This Hazardous Weather Outlook is for portions of Puerto Rico. .DAY ONE...Today and Tonight .Lightning...Isolated thunderstorms, particularly across central to northern and northeastern sections of Puerto Rico in the afternoon, but lingering into the evening hours. Stay alert and be prepared to take shelter if storms develop. .Excessive Rainfall...Flooding in urban areas, roads, small streams, and washes, particularly across areas experiencing lightning impacts. 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 urban and coastal areas. .Rip Currents...Life-threatening rip currents are possible in the surf zone, particularly across northern and eastern Puerto Rico and Culebra. Isolated stronger rip currents may occur elsewhere, especially near piers, jetties, and channels. .DAYS TWO THROUGH SEVEN...Saturday through Thursday Daily afternoon thunderstorms will bring limited to elevated flooding and lightning risks, focusing over northern Puerto Rico tomorrow Saturday before shifting back toward northwestern sections Sunday onwards. A frontal boundary and pre-frontal trough will enhance moisture, instability, and weak steering flow, allowing storms to persist longer and increase impacts through the weekend. Heat hazards will remain limited to elevated through the weekend, although gradually diminishing. A moderate rip current risk continues along northern beaches, but incoming long- period swells late in the weekend will create hazardous to life- threatening surf and rip currents, while strengthening winds may further deteriorate marine conditions and pose coastal wind hazards. .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. $$
