Weather Summary for Puerto Rico
National Weather Service San Juan PR
402 AM AST Wed Dec 12 2018
Most clear skies were observed during the overnight period and
this morning. TJUA Radar detected a few showers across the
Atlantic and Caribbean waters with light rainfall amounts.
Overnight low temperatures were near the upper 60s to the lower
70s in lower elevations, and the lower to middle 60s in higher
elevations. Winds were out of the east to northeast at 5 to 10
mph.
A stable air mass remains in place, but a shear line to the north of
Puerto Rico will pull moisture across Puerto Rico and increase rain
chances for portions of northern, interior and western Puerto Rico.
Showers that do develop will be short-lived due to drier air that
remains in the mid to upper-levels of the atmosphere. A ridge of
high pressure will strengthen across the area early Thursday and
remain anchored overhead through Friday. The upper level ridge will
bring low-level moisture across the island periodically over the
next several days which will help induce showers. Today`s high
temperatures will be near the middle to upper 80s near coastal
areas, and the middle 70s to the upper 70s in higher elevations.
Across the local waters, seas will remain between 3 to 5 feet,
through early Thursday. Then seas will increase as a result of a
northwest swell that is forecast to move into the Atlantic and
Caribbean waters.
