Fire Weather Planning Forecast for the Florida Keys
National Weather Service Key West FL
407 AM EDT Mon Sep 15 2025

.Discussion...
Relatively drier air is still in place, but some rainfall cannot
be ruled out as a stubborn, weak surface boundary will remain
draped across the nearby area. Today will look very similar to the
past couple of days with some pop up activity mainly in the
evening, but overall fire weather concerns will be minimal.
Minimum relative humidity values will remain above 60%, especially
beyond today as another round of moisture pushes in during the
middle of the week.
