NWS Marine Forecast


   AMZ700-180915-  415 PM AST Wed Jun 17 2026    .Synopsis for Puerto Rico and the U.S. Virgin Islands Waters....    A broad surface high pressure building over the Central Atlantic  will promote moderate to locally fresh east to east-southeast winds  for the next several days, resulting in choppy seas across the local  waters and Caribbean passages that could lead to hazardous  conditions for small craft. Shower activity will gradually increase  by tomorrow, Thursday, morning into Friday, as a tropical wave  approaches the Caribbean Basin, leading to localized heavy rainfall,  gusty winds, and reduced visibility. A dense layer of Saharan Dust  will also gradually filter into the region by late Thursday,  resulting in hazy skies, reduced visibility, and poor air quality  through Saturday.    $$
