Fire Weather Planning Forecast for the Florida Keys
National Weather Service Key West FL
428 AM EDT Wed Mar 11 2026

.Discussion...
High pressure centered near Bermuda will continue to promote
gentle to moderate east to southeast breezes through Thursday
morning. As the high retreats farther out into the North Atlantic,
breezes will shift to the southeast to south and eventually the
south to southwest as a frontal system approaches the area. Drier
air remains entrenched across the Keys through tonight resulting
in near nil rain chances. Small increase in moisture is expected
on Thursday leading to slight chances of showers. While showers
creep into the forecast for Thursday, it still won't be nearly
enough to provide much relief from the ongoing drought conditions.
However, there are signals some beneficial rain may be on the way
for Friday through the weekend. Expect temperatures to remain
above normal. Min RH values will be in the mid 60s percent today
and Thursday with good RH recovery into the upper 80s percent
overnight.
