1020 PM EDT Fri Sep 20 2024
.UPDATE...
Issued at 1020 PM EDT Fri Sep 20 2024
Noticeably less coverage of showers and storms today due to drier
air. Low level moisture is sufficient to produce isolated showers
over the Atlantic waters. NE flow will push these showers SW and
onshore portions of the Space and Treasure coasts. Most areas will
remain dry but brief downpours and occasional lightning strikes
will be possible along the coast so have extended the small PoP
through the overnight. No significant change to min temps in the
low to mid 70s, possibly holding in the upper 70s along the
immediate Volusia and Brevard coasts due to persistent onshore
(NE) flow.

.AVIATION...
(00Z TAFs)
Issued at 755 PM EDT Fri Sep 20 2024
Mainly VFR conditions are forecast through the TAF period. Will
maintain VCSH at coastal terminals MLB-SUA overnight for Atlc
showers pushing onshore which may produce brief MVFR conds. VCSH
will continue along the coastal terminals through Sat morning
transitioning to the interior in the afternoon. Added VCSH for
MCO/SFB aft 18Z. Light winds tonight will increase from the NE
10-15 knots with gusts near 20 knots.

.MARINE...
Issued at 345 PM EDT Fri Sep 20 2024
Current-Tuesday...(Modified Previous Discussion) Boating conditions
slowly become poorer over the next few days as onshore winds
increase. As high pressure settles into the Appalachians, northeast
winds freshen to 8-13 KT this afternoon and will persist through the
weekend. Isolated to scattered showers and a few storms possible
each day, especially from Cape Canaveral southward. By early next
week, winds turn more easterly at 10-15 KT. Seas 2-4 FT through
Saturday before building to 3-5 FT Sunday-Monday, and up to 6 feet
in the offshore waters on Tuesday, largely driven by a northeast
swell at 9-11 sec.
