Fire Weather Planning Forecast for Puerto Rico
National Weather Service San Juan PR
349 AM AST Fri Jul 5 2024
.DISCUSSION...
Light to moderate east-southeasterly winds will prevail today.
Expect residual moisture associated to the exiting tropical wave
to prevail across the islands. Drier air will start to filter
into the area today, however some showers are expected to develop
in the afternoon across the interior and western Puerto Rico.
Currently, KBDI values continue below the critical threshold. A
low fire weather risk continues across the islands because the RH
and winds will remain outside of the threshold criteria. However,
we urge people to stay inform with our latest updates.
