Weather Summary for Puerto Rico
National Weather Service San Juan PR
518 PM AST Sat Jan 19 2019

A fair weather pattern prevailed today across most of the area
except for portions of interior, and western areas were showers
developed as a result of local and diurnal effects. Rainfall
amount ranged from one to two inches in isolated areas.

Today high temperatures were near the lower to middle 80s in lower
elevations, and the lower to middle 70s in higher elevations with
east to southeast winds of 10 to 15 mph. Tonight temperatures
will fall to upper 60 to lower 70s in lower elevations, and the
low to middle 60 in higher elevations. Winds will become light and
variable during the overnight period.

Tomorrow fair weather is expected to continue, as a result of a dry
air mass, and a surface high that will build over the region late
tonight. However, showers are possible across portions of the
interior, and western areas of Puerto Rico due to local and
diurnal effects.


Marine conditions will remain relatively quiet through the
weekend with seas of 3 to 5 feet, with easterly winds of 10 to 20
knots. Small craft operators should exercise due to the stronger
winds across the local waters. There is a moderate risk of rip
currents for the northwestern to northeastern beaches of Puerto
Rico as well as Vieques and Culebra.
