Hazardous Weather Outlook National Weather Service San Juan PR 426 AM AST Thu Nov 20 2025 AMZ711>745-PRZ001>013-211000- 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- 426 AM AST Thu Nov 20 2025 This Hazardous Weather Outlook is for portions of Puerto Rico. .DAY ONE...Today and Tonight .Lightning...Isolated thunderstorms are expected, particularly across coastal areas early in the day and again after sunset. During the afternoon, the greatest risk will be across the interior to western and southwestern Puerto Rico. Stay alert and be prepared to take shelter if storms develop. .Excessive Rainfall...Flooding of urban areas, roads, small streams, and washes is possible, especially across the interior to western and southwestern Puerto Rico. There is a low chance of isolated flash floods, mainly across southwestern PR where convection is expected to persist. Elsewhere, expect water ponding on roads and in poorly drained areas. .Rip Currents...Life-threatening rip currents are likely in the surf zone. These dangerous conditions are expected across north- and east-facing beaches of Puerto Rico and the northern beaches of Culebra, with isolated stronger rip currents possible elsewhere, especially near piers, jetties, and channels. .DAYS TWO THROUGH SEVEN...Friday through Wednesday Localized and limited excessive rainfall and lightning risks may continue through Friday, but conditions will trend more stable and drier through the weekend and into early next week. The risk of rip currents will drop to moderate on Friday and low on Sunday, then increase back to moderate early next week, with life- threatening conditions possible in moderate-risk areas. A limited non-thunderstorm wind risk is possible across the local waters and exposed coastal areas early next week. Increasing winds and incoming northerly swells may also generate hazardous seas for small craft by Tuesday and Wednesday, which could further elevate rip current risk during that period. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed. $$
