Weather Summary for Puerto Rico
National Weather Service San Juan PR
454 PM AST Mon Jun 24 2019

Mainly fair weather conditions dominated during the morning hours
across the local archipelago. Showers and thunderstorms developed
across the western interior this afternoon. Periods of heavy
rain were detected, and rainfall accumulations ranged between 1
and 2.5 inches. Maximum temperatures ranged from the upper 80s to
the lower 90s at the coast and in the mid 80s in the mountains.
Winds were from the east at 10 to 20 mph with sea breeze
variations along the coastal areas.

A tropical wave will move across the local islands this evening
into tomorrow. This wave will bring shower and thunderstorm
activity across the local waters and some of them will move inland
across the windward sections of east and southeast Puerto Rico
overnight. Then, the tropical moisture combined with local effect
and diurnal heating will aid in the development of afternoon
showers and isolated thunderstorms, mainly across portions of
interior and northwestern Puerto Rico. Other areas, like east PR
and San Juan and vicinity, could see isolated to scattered
activity as well. Winds will be out of the east at 10 to 15 mph.

Across the regional waters, expect seas between 1 to 5 feet with
winds out of the east at 10 to 15 knots. Thunderstorm formation
will be possible as the wave moves across the local waters. A
low risk of rip currents is expected this evening.
