Hydrologic Outlook
National Weather Service San Juan PR
402 AM AST Sun Apr 13 2025

...THE WET PATTERN WILL CONTINUE ACROSS THE ISLANDS THROUGH MUCH OF
THE WEEK...
...THIS MARKS THE BEGINNING OF THE EARLY WET SEASON...

Showers and thunderstorms have increased in frequency in the past
couple of days, mostly in the afternoon hours for portions of the
east, west, north and interior of Puerto Rico. This pattern will
continue through much of the workweek, as a series of frontal
boundaries and troughs continue to reach the islands.

In general, these same areas should see the bulk of the rainfall
activity each day of the workweek, but showers will also stream
occasionally across portions of the Virgin Islands and the San Juan
metro area as well.

So far, there is a small rainfall deficit along the north-central
and northwest of Puerto Rico. However, with the forecast rainfall
for this week, these deficits are expected to ease. On the other
hand, areas that receive frequent heavy showers could see an
elevated risk of urban and small stream flooding, as well as
isolated mudslides and rapid river rises.

The seasons in the northeastern Caribbean are better defined by
rainfall rather than by temperatures. For Puerto Rico and the Virgin
Islands, the onset of the early wet season occurs in mid-April,
stretching all the way into May, followed by the mid-summer drought,
which is observed through much of June and July.
