Weather Summary for Puerto Rico
National Weather Service San Juan PR
508 AM AST Tue Jan 21 2020

Partly cloudy skies with light rain prevailed during the overnight
hours, across the eastern and northern areas of Puerto Rico.
Rainfall amounts were less than a tenth of an inch. Overnight low
temperatures were near the upper 60s to the lower 70s near coastal
locations, and the lower to the middle 60s in higher elevations.
Surface winds of 10 to 15 mph prevailed this morning.

A drier air mass will continue to move into the area today;
however, afternoon showers are possible as a result of local and
diurnal effects. Showers that do develop will be short-lived and
produce light rainfall amounts. Today`s high temperatures will be
near the lower to middle 80s in lower elevations, and the middle
to upper 70s in higher elevations.Southerly winds will cause
warmer temperatures along the northern coast today and Wednesday.
A wetter pattern is forecast late Wednesday night into Thursday as
a pre-frontal boundary moves over Puerto Rico and increase rain
chances. The frontal-boundary, coupled with southerly wind flow,
and upper-level support, will aid in the development of isolated
thunderstorms and moderate to heavy rainfall.


Hazardous marine conditions continues due to a combination of a
subsiding northerly swell and wind-drive waves. The wind and
swell event is expected to last at least through Tuesday. Marine
conditions are expected to gradually drop below Small Craft
Advisory criteria by Tuesday evening into Wednesday.
