Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
516 AM AST Fri Jul 21 2017

.DISCUSSION...Overall moisture is expected to decrease a little
bit today across the local islands as a patch of relatively drier
air moves in. It is breezy and the relative humidity will be close
to the critical thresholds for a brief time across the South
Coastal Plains. For that reason there is a slightly higher than
normal chance of wildfires today, mainly across the Southeastern
Coastal Plains since the soil moisture in Camp Santiago is under
10 percent and the KBDI is estimated to be over 700.
