Hydrologic Outlook

National Weather Service San Juan PR

1230 PM AST Thu May 15 2025



...THERE IS A RISK FOR FLOODING ACROSS PUERTO RICO AND THE U.S. 

VIRGIN ISLANDS, PARTICULARLY FRIDAY AND SATURDAY...



An upper-level trough moving across the northeast Caribbean combined 

with abundant moisture will result in showers and thunderstorms 

across the local island Friday and Saturday. 



Based on the latest guidance, there is a chance to observe periods 

of showers and thunderstorms Friday and Saturday. The areas expected 

to receive the highest rainfall totals include northwest, central 

and the eastern coastal areas of Puerto Rico as well as Vieques, 

Culebra and the US Virgin Islands. Across these areas there is a 

moderate chance(40-60%) to observe 2 to 4 inches with locally higher 

amounts of up to 6 inches. Due to already saturated soils and rivers 

and tributaries running well above normal levels, there is a risk 

for flooding across Puerto Rico and the US Virgin Islands on Friday 

and Saturday.



Any prolonged period of heavy rainfall will result in urban and 

flash flooding, river flooding and mudslides particularly across 

central and east Puerto Rico where rainfall has been abundant over 

the past month.
