Fire Weather Planning Forecast for the Florida Keys
National Weather Service Key West FL
501 AM EDT Sat Aug 23 2025

.Discussion...
A weak subtropical high pressure ridge will dominate the pattern
for the weekend continuing into the middle of next week. This will
result in mainly light breezes, occasionally becoming variable
and light to gentle. Even though moisture remains quite plentiful
for the weekend and into early next week, we lack a significant
trigger to initiate more widespread showers and thunderstorms.
Therefore, slightly below normal PoPs (20%) remain through at
least the middle of next week. Min RH values are expected to be in
the lower 60s percent today and Sunday with good RH recover to
the upper 80s percent tonight.
