Weather Summary for Puerto Rico...CORRECTED
National Weather Service San Juan PR
521 AM AST Tue May 22 2018

Partly cloudy skies were observed across Puerto Rico during the
overnight hours. Mainly fair weather was observed but a few brief
showers affected portions of eastern and northern Puerto Rico,
leaving up to a half an inch of rain across isolated areas in the
eastern interior and between a half to three quarters of an inch
of rain across portions of the San Juan metropolitan area.
Overnight temperatures were in the low to mid 70s across the lower
elevations and in the mid 60s to around 70 degrees across the
higher elevations. Winds were from calm to light and variable.

Brief showers are expected to continue affecting the local waters
and the eastern sections of Puerto Rico during the morning hours.
Shower development is expected across the western interior and
western sections of Puerto Rico this afternoon. Some showers are
also expected in and around the San Juan Metro area in the late
morning into the afternoon hours. The daytime maximum temperatures
are expected to be in the mid 80s to around 90 degrees across the
lower elevations and in the upper 70s to mid 80s across the
higher elevations. This weather pattern is expected to continue
for the next few days, but there may be slightly higher shower
activity on Wednesday and Thursday due to an increase in moisture.

Across the regional waters, small craft operators should exercise
caution due to seas up to 6 feet. Winds will be from the east at
10 to 20 knots. There is a moderate risk of rip currents for many
of the local beaches.
