Special Marine Warning 158, NWS Melbourne, FL

Area Forecast Discussion
National Weather Service Melbourne FL
950 PM EDT Wed Aug 25 2021

.DISCUSSION...

A TUTT low is centered over the FL straits with a mid level trough
extending from the SW Atlc into the NW Caribbean. These features are
enhancing deep convection over the Atlc just offshore the Treasure
coast. These storms will push onshore Martin/St Lucie/Indian River
counties through midnight and produce strong wind gusts along the
coast, 40-50 mph with isolated damaging wind near 60 mph possible.
Convection will push well inland across Okeechobee/Osceola counties
and also up the coast, affecting Brevard/Volusia counties and
Orlando metro later tonight. Locally heavy rains will produce a
quick half inch to one inch with up to 3 inches possible where
repeated rounds of heavy rain occurs. This will likely causing some
temporary flooding of low lying areas and where recent heavy rains
have occurred.

&&

.AVIATION...
Numerous SHRA/TSRA will push onshore through 04Z VRB-SUA with gusty
winds 35-40 knots possible. Additional storms will affect
MLB/TIX/MCO aft 04Z. Gusty winds 30-40 knots will be possible at
coastal terminals with this convection. Later tonight and early Thu,
coverage will be much lower across the southern terminals with bulk
of the showers and storms initially MCO northward. Coverage should
decrease across the north by 16Z or so.

&&

.MARINE...
Have expanded the Caution headline for the overnight to include all
marine zones except nearshore Volusia. Expect East winds 15-20 knots
to spread northward with seas 4-5 ft. The primary concern is strong
storms over the Atlc pushing west toward the coast this evening and
overnight, capable of strong winds and possible waterspouts.

Thu...Winds will subside to 10-15 knots and seas slowly diminishing.
High coverage of showers and storms will persist in the morning esp
Cape northward. Small craft should exercise caution may need to
persist thru the morning for the northern offshore waters.
