Weather Summary for Puerto Rico
National Weather Service San Juan PR
523 AM AST Thu Jan 23 2020

Clouds and some showers moved across Puerto Rico, but some areas
in the north remained mostly clear. The heaviest amounts fell
between Guanica and Guayanilla and ranged from one half to one
inch. Other showers formed along the Cordillera Central and
western Puerto Rico, but were mostly below one half inch. Winds
were light and variable and less than 10 mph. Minimum temperatures
remained in the mid to upper 70s in the lower elevations, but
were in the mid to upper 60s in the mid and upper elevations.

Bands of moisture forming ahead of a cold front now draped across
the Dominican Republic were responsible for the showers and as
the front approaches they will increase during the day. The front
is expected to reach Puerto Rico by midday and travel across the
island this afternoon and evening. The best rain is expected this
afternoon and this evening, but showers will continue through the
weekend. Highs today will range from the mid and upper 80s in the
lower elevations to the mid and upper 70s in the higher terrain.
Lows tonight will be in the 60s and 70s. Winds will be variable
less than 10 mph until late in the day. Winds behind the front
will become northerly but should remain less than 10 mph except in
northwest Puerto Rico.

In the local Atlantic waters, seas are around 3 to 5 feet and will
remain so through most of the day today, They are forecast to
begin to increase tonight, to around 4 to 6 feet and then become
hazardous on Friday as northerly swell reaches the area from the
developing low pressure. In the Caribbean waters, wave heights
will remain below 5 feet until Saturday. There is a moderate risk
of rip currents at north-facing beaches today and tonight, but the
rip current risk will become high on the north coast by Friday.
