Fire Weather Planning Forecast for the Florida Keys
National Weather Service Key West FL
423 AM EDT Fri Aug 29 2025

.Discussion...
Slightly above normal rain chances are expected through the
upcoming weekend. This is due to a quasi-stalled frontal boundary
that remains across central to northern Florida with moisture
pooling south of this boundary. At the same time, high pressure
across the region is slowly shifting east, which will leave the
Keys under a light wind regime. This will promote fair to poor
dispersion indices for today and Saturday. Min RH values are
expected to be in the mid to upper 60s percentile today with good
RH recovery to near 90 percent overnight.
