Weather Summary for Puerto Rico
National Weather Service San Juan PR
453 AM AST Sun Jan 24 2021

Fair weather under mostly clear skies was observed across Puerto
Rico, Vieques and Culebra through the nighttime hours. The Doppler
radar detected isolated showers over the local waters, but none
over land areas. The overnight low temperatures were in the upper
60s to low 70s across the lower elevations, while the higher
elevations observed temperatures from around 60 degrees to the mid
60s. The wind was light and variable.

For today, a slight chance of showers is forecast for eastern
Puerto Rico early in the morning, but scattered showers are
forecast for the interior to the southwestern sections of Puerto
Rico in the afternoon. The amount of rain forecast is not expected
to cause flooding, but poor drainage areas could observe some
ponding of water. The daytime temperatures will be in the low to
mid 80s across the lower elevations, while the higher elevations
will observe temperatures in the mid 70s to low 80s. The wind will
be from the northeast with sea breeze variations at around 10
mph.

Across the regional waters, seas up to 5 feet and winds between 5
to 15 knots are expected today. There is a moderate risk of rip
currents for the beaches of northwest to northeast Puerto Rico,
beaches of Culebra and the north and east beaches of Vieques.
