 Hazardous Weather Outlook
   AMZ700-221415-  912 PM AST Tue May 21 2024    .SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...  The interaction of an induced surface trough to the west and a weakening  surface high pressure to the east will promote moderate east-southeast  winds through Wednesday. As the surface trough moves closer to the region  expect increasing shower and thunderstorm activity across the local waters  from Wednesday onwards. In addition, the proximity an amplifying mid  to upper level trough just west of the region will enhance thunderstorm  development as well as increase winds and the potential for squally conditions  across the Mona Passage and Atlantic waters by late Wednesday night and  through at least Friday. Winds are forecast to diminish once again by  the weekend.      $$
