 Hazardous Weather Outlook
   AMZ700-202015-  400 AM AST Sat Sep 20 2025    .SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...    A surface high pressure, in combination with Tropical Storm  Gabrielle located about 550 miles east-northeast of the northern  Leeward Islands, will continue to result in a gentle to light  southeasterly wind flow across the local waters through the rest of  today into the weekend. As a result, seas will range from 2 to 6  feet across most of the waters. Localized hazardous marine  conditions are possible due to showers and thunderstorms that could  produce locally higher seas and gusty winds. A long-period  northeasterly swell generated by Tropical Storm Gabrielle, currently  moving over the central Atlantic, will reach the local waters and  passages during the weekend. However, seas are forecast to remain  with or below Small Craft Advisory criteria.    $$
