.DISCUSSION...
Issued at 1014 PM EDT Fri Aug 8 2025
A wet, messy pattern continued over the Florida Keys for the
evening hours. Deep thunderstorms developed north and south of
Key West before sunset, and a line of heavy rain and gusts that,
surprisingly, originated over Cuba, were responsible for a burst
of 39 mph winds at Key West Airport, thunderstorms, and a quarter
of an inch of rainfall. The KKEY 00Z sounding, released ahead of
the rainfall, sampled an environment with a PWAT of 2.34 inches, a
new daily record with a deep layer of instability for showers to
harness. However, a shallow layer of inhibition was observed, and
the atmosphere will become less favorable for heavy rainfall as we
move into the weekend.

The tropical easterly wave responsible for the prior few days of
heavy rain will continue its westward track overnight and
tomorrow. Winds across the Keys are expected to remain
southeasterly while a high pressure system builds off the
US northeast coastline. Overall moisture will remain high through
the next 24 hours, and an overnight pulse in winds across the reef
may occur. In sum, electing not to change the inherited forecast
due to the continued favorable environment for above normal
showers. Expect further light shows around the Keys to mark the
weekend!

.MARINE...
Issued at 1014 PM EDT Fri Aug 8 2025
No long fuse watches, warnings, or advisories are currently in
effect for the Florida Keys waters. From synopsis, a tropical wave
will continue slowly progressing westward through the Keys
overnight through Saturday. This will promote light to gentle east
to southeast breezes (occasionally light to moderate breezes) as
well as above normal rain and thunder chances. As the wave
continues progressing further into the Gulf heading through the
weekend, surface high pressure across the Atlantic will slowly
build into the Keys. This will result in gentle to moderate east
to southeast breezes for early next week.

.AVIATION...
(00Z TAFS)
Issued at 1014 PM EDT Fri Aug 8 2025
Prevailing VFR conditions at EYW and MTH will be interrupted by
short-lived bursts of showers and thunderstorms during the 00Z
TAF period. Periods of MVFR to IFR VIS and CIGs are expected in
showers, and LIFR conditions are possible in extremely heavy
rainfall. Shower coverage is forecast to increase before sunrise,
and a lull in the afternoon is possible.
