Weather Summary for Puerto Rico
National Weather Service San Juan PR
523 PM AST Fri Mar 24 2017
Mostly cloudy skies prevailed across Puerto Rico this afternoon.
Moderate to heavy showers developed across the interior sections
of Puerto Rico and affect mainly the northern half of Puerto Rico.
Rainfall amounts were between one half to one inch. Maximum temperatures
ranged from the low to mid 70s in the mountains to the upper 70s
to low 80s at lower elevations. Winds were generally south at 10
to 15 mph.
For tonight, the south wind flow will continue to transport areas
of cloudiness with showers across the local islands. For the
upcoming weekend, a surface trough will develop across the western
Atlantic. This surface trough will bring deep tropical moisture
across the region Saturday and Sunday. As a result, periods of
scattered to numerous showers and possible thunderstorms are
expected to affect the region both days. These showers are likely
to result in urban flooding as well as rises along small streams
and rivers particularly across eastern Puerto Rico.
Seas are expected to deteriorate starting tonight as a northwest
swell arrives across the Atlantic waters. As a result, small craft
advisories will be in effect from late tonight through at least
Sunday evening as seas up to 7 feet are expected. Elsewhere, seas
between 3 to 5 feet with winds up to 15 knots are expected.
