Weather Summary for Puerto Rico
National Weather Service San Juan PR
441 AM AST Sat Jan 6 2018

Doppler radar indicated isolated to scattered showers moving west
northwestward from the local waters with few of them affecting the
U.S. Virgin Islands, Vieques, Culebra as well as the eastern and 
southeastern sections of Puerto Rico but the accumulations were 
minimal. The overnight minimum temperatures were in the low to mid
70s across the lower elevations and in the 60s across the higher 
elevations. The winds were mainly from the east southeast at less
than 10 mph. 

Small areas of low level moisture embedded in the trades will 
continue to move across the local islands from time to time 
producing brief periods of passing showers during the rest of the 
morning hours. Isolated to scattered showers are also expected to
develop this afternoon across western and interior sections of 
Puerto Rico. However, not significant or widespread precipitation 
is expected. Latest satellite images are showing another area of 
low level moisture over the Leeward islands that is forecast to 
move west and affect the local islands late this afternoon and 
tonight. This area of moisture is expected to remain across the 
region through Sunday morning. Model guidance suggests that a 
drier and more stable airmass will move over the region Sunday 
afternoon, limiting the shower activity through at least mid week.

Seas up to 10 feet are expected across the Atlantic waters today 
with seas up to 8 feet across the Anegada Passage. Seas will
increase across the rest of the local waters today and tonight.
Therefore, Small Craft Advisories are in effect for most of the 
local waters. Additionally there is a High Surf Advisory for the 
the northern shores of Puerto Rico and Culebra and a high risk of
rip currents for all of the local islands except the south 
shores of Puerto Rico.
