Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
521 AM AST Mon Apr 24 2017

.DISCUSSION...Moist and unstable conditions will keep the potential
for showers and a few thunderstorms high through at least Tuesday.
As a result...relative humidities will remain above critical levels
over the next few days. Winds will subside and shift to the south-
southeast over the next few days as a surface low moves over the
Western Atlantic. Conditions will gradually improve between Wednesday
and Thursday as mid level ridge builds over the Central Caribbean.

Outlook...Low fire danger will likely prevail through midweek.
However...elevated fire danger is possible near Camp Santiago on
Thursday.
