Weather Summary for Puerto Rico
National Weather Service San Juan PR
520 PM AST Fri Apr 20 2018

Showers rolled through eastern Puerto Rico during the morning
hours leaving one tenth to just under one half inch at a number
of stations--one of which was Barrio Montones near Las Piedras on
Rio Valenciano with 0.43 inches. Later during the afternoon
showers and thunderstorms fired off and subsided and fired off
again. Of the gages functioning, Lares in the Guajataca Basin
received 0.85 inches during the day today and Utuado on the Rio
Tanama received 0.39 inches. These storms would have left more but
moderate east southeast trade wind flow of 15 to 25 mph was not
allowing them to contribute much before they were pushed along.
Temperatures ranged from the lower 90s on the south coast, to the
mid 70s in the higher elevations. San Juan had a high of 85
degrees, a low of 75 so far and a total of 0.06 inches since
midnight. Winds at the Luis Munoz Marin Airport gusted to 31 mph
this afternoon.

There will be a brief pause in the shower activity later tonight
before another band of moisture moves through on Saturday.
Similar showers and isolated thunderstorms will develop over
western and interior Puerto Rico during the afternoon. Gusty winds
of 15 to 25 mph will also be seen in the afternoon, though
lighter in the interior. Lows tonight will range from the mid 60s
to mid 70s and highs tomorrow will range from the mid 70s to
around 90 degrees, the warmest being on the south coast.

A small craft advisory continues in effect for seas up to 8 feet
across the outer Atlantic waters and up to 7 feet across the outer and
Caribbean offshore waters and the local passages. Small craft will
need to exercise caution elsewhere. There is a moderate to high
risk of rip currents tonight across all of the local beaches.
Tomorrow only moderate to low risk will be seen--the low risk
being along the western coast of Puerto Rico.
