Weather Summary for Puerto Rico
National Weather Service San Juan PR
505 AM AST Sat Jun 25 2022

Mostly clear to partly cloudy skies prevailed over land areas overnight.
However patches of low level moisture with embedded tradewind showers
continued to move across the regional waters. The presence of an upper-
level trough continued to aid in enhancing some of these showers, some
of which were reaching the windward side of the islands from time to
time. So far rainfall accumulations were minimal and the showers were
brief. Low temperatures were in the mid to upper 70s across the lower
elevations and in the upper 60s to low 70s in higher elevations. Winds
were calm to light and variable but briefly higher with the passing
showers.

For the rest of today, expected mostly sunny skies across much of
the region by late morning, however the combination of available
moisture along with good daytime heating, local effects and the upper
trough, will favor afternoon showers and possibly isolated thunderstorm
development mainly over parts of northwest Puerto Rico. Lesser shower
activity is expected elsewhere including across parts of the San Juan
metro where a few brief showers cannot be ruled out. High temperatures
will be in the upper 80s to low 90s, with maximum heat indices forecast
to reach between 100-108 degrees along portions of the north coastal
and urban areas. Winds will be generally from the southeast at 10 to
15 mph with higher gusts and sea breeze variations.

Across the local waters, light to moderate east to southeast winds
are expected with speeds between 10 to 15 knots. Seas of 4 feet or
less are expected for the near shore waters and between 5 to 6 feet
for offshore Atlantic waters and some of the local passages. Winds
will be from the east southeast 10 to 15 knots.

There is a high risk of rip currents for some of the north central
beaches of Puerto rico and a moderate risk for most of the remaining
beaches including Culebra and Vieques.
