National Weather Service SAN JUAN PR
528 AM AST Tue Nov 21 2017

.DISCUSSION...Gentle east southeasterly trade winds with sea

rain amounts and coverage in showers will be greatly reduced.
Nevertheless previous wet conditions and winds less than 15 mph
with good relative humidities will keep fire danger low.
