Weather Summary for Puerto Rico
National Weather Service San Juan PR
417 PM AST Thu Sep 20 2018
A weak tropical wave left shower activity across the southwest,
and southeast quadrant of Puerto Rico early this morning. Then,
skies turned hazy as a dense Saharan Air Layer moved through the
region. A few short fuse rains were detected with the Doppler
Radar but in general no shower activity was observed over land
today. High temperatures were in the low and mid 90s along the
coastal areas and in the mid 80s along the mountain areas. The
wind was mainly from the east-southeast at 15 to 20 knots with sea
breeze variations.
Satellite imagery and model guidance are indicating dry and dusty
conditions through at least Friday. This air mass combined with a
mid to upper level ridge will limit shower activity and will
result in hazy skies through at least the end of the work-week.
Short life rainfall activity should not be ruled out mainly over
west PR Friday afternoon.
Seas will range between 4 and 6 feet with east southeast winds at
15 to 20 knots mainly across the Atlantic Offshore waters,
Caribbean waters and Mona Passage. Therefore, small boat
operators should exercise caution across these waters. Elsewhere
seas and winds are forecast to slowly return between 2 and 5 feet
and around 15 knots, respectively.
