Stay alert and be prepared to take shelter if storms develop. .Excessive Rainfall...Ponding of water is possible on roads and in poorly drained areas, especially where persistent rain or brief heavy downpours occur across southwestern Puerto Rico. There is a low chance of localized urban and small-stream flooding. .Rip Currents...Life-threatening rip currents are possible in the surf zone, particularly along north- and east-facing beaches of northern Puerto Rico and Culebra. Isolated stronger rip currents may also occur elsewhere, especially near piers, jetties, and channels. .DAYS TWO THROUGH SEVEN...Saturday through Thursday Quiet conditions are expected through Monday, with only a moderate rip current risk on Saturday and no significant hazards Sunday or Monday. By Tuesday, strengthening winds and an arriving northeasterly swell will begin increasing rip current and small- craft risks. These hazards may peak on Wednesday, when stronger winds and building seas could produce a high life-threatening rip current risk, hazardous marine conditions, and a limited non- thunderstorm wind risk along exposed areas. Elevated winds and swell may keep higher risks in place late in the week. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed. $$ AMZ716-726-VIZ001-002-221000- St. Thomas St. John adjacent Islands-St Croix- Nearshore Atlantic and adjacent Caribbean Coastal Waters- 333 AM AST Fri Nov 21 2025 This Hazardous Weather Outlook is for portions of USVI. .DAY ONE...Today and Tonight .Rip Currents...Life-threatening rip currents are possible in the surf zone, particularly along north- and east-facing beaches of Saint Croix.
