Fire Weather Planning Forecast for the Florida Keys
National Weather Service Key West FL
430 AM EDT Tue Mar 31 2026

.Discussion...
Strong high pressure over the central North Atlantic will meander
for several days. This will continue to promote moderate to fresh
easterly breezes through much of the week. Moisture undulations
around the high will result in episodic showers through Wednesday.
Some periods may be wetter than others. Min RH values will be in
the mid 60s percent today and near 60 percent Wednesday with good
RH recovery into the mid 80s percent overnight. Moderate drought
conditions will persist for the entire island chain. Even though
showers are in the forecast over the next several days, it is not
expected to be nearly enough to dent the drought conditions.
