We are promoting the use of the Experimental Graphical Hazardous Weather Outlook (GHWO), which provides a graphical depiction of potential weather hazards for up seven days. Please refer to our GHWO at https://weather.gov/erh/ghwo?wfo=sju. The GHWO produces clear, concise, multi-level color-coded graphics that provide decision makers with convenient access to potential weather hazard information and associated risks out to seven days. For any comments or questions on the elimination of the text Hazardous Weather Outlook, or the Experimental Graphical Hazardous Weather Outlook, please contact our webmaster account at sr-sju.webmaster@noaa.gov. This Hazardous Weather Outlook is for portions of Puerto Rico. .DAY ONE...Today and Tonight .Excessive Rainfall...Ponding of water in roads and poorly drained areas, particularly across |eastern and northwestern Puerto Rico, Vieques, and Culebra. There is a low chance of localized urban and small streams flooding. .Wind...Breezy conditions (18-22 kts | 21-25 mph), particularly across coastal areas. Unsecured items could blow around. .Marine Conditions...Small craft should exercise caution, particularly across Atlantic waters and Anegada Passage. .Rip Currents...Life-threatening rip currents are possible in the surf zone, particularly across northern and eastern exposed beaches. Isolated stronger rip currents may occur elsewhere, especially near piers, jetties, and channels. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday Winds will continue to increase late in the week, leading to breezy to windy conditions across coastal and elevated areas, lightweight outdoor items may be blown around in exposed locations. Marine and beach conditions will deteriorate during the second part of the workweek as increasing winds and an incoming long- period northerly swell raise seas and rip current risks. High Rip Current Risk Statements and Small Craft Advisories are possible. An approaching trough could result in an increase in the frequency of showers by early next week. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed. $$ AMZ716-726-VIZ001-002-110915- St. Thomas St. John adjacent Islands-St Croix- Nearshore Atlantic and adjacent Caribbean Coastal Waters- 504 AM AST Wed Dec 10 2025 The final text product of the legacy Hazardous Weather Outlook (HWO) will be issued on December 15th, 2025.
