942 AM EDT Sat Sep 21 2024
...New UPDATE...
.UPDATE...
Issued at 941 AM EDT Sat Sep 21 2024
Current-Tonight...Troughiness in the mid-levels will continue to
weaken and push seaward over the next 24 hours. Stout mid-level high
pressure over Texas will expand eastward with mid-level heights
rising across the GoMex and FL peninsula. Light morning winds at the
surface will become NERLY and increase 10-15 mph with higher
afternoon gusts; we may see some coastal locations average 15-20 mph
this afternoon for wind speeds. A diffuse sea breeze will develop
and push inland. Only modest deep layer moisture is present and our
precip chances will remain below normal with 20pct north/west of I-4
and highest up to 40pct across the Space and Treasure coasts.
Storm motion will be fairly slow and out of the north to
northeast. Lightning strikes, heavy downpours, and gusty winds
locally will be the main threats. Activity diminishes this
evening, though will retain a small PoP along the coast overnight
for ISOLD "low-topped" convection chances. Afternoon highs in the
U80s to around 90F. Peak heat indices this afternoon more-or-less
seasonal in the M-U90s. Overnight mins generally in the L-M70s
while conditions remain humid.
There will be a HIGH risk for numerous, strong, life-threatening rip
currents at the beaches along Volusia and north Brevard counties,
while a Moderate risk continues southward through Martin County.
Additionally, minor coastal flooding remains a concern during high
tide. The highest water levels are forecast in the late morning
hours with a secondary peak in the late evening.

activity to persist into early afternoon, with VCTS included for
MLB southward after 14Z. By 18Z, showers with embedded lightning
storms are forecast to push inland, clearing interior locations by
around 0Z. Models suggest LEE remaining dry, so have forgone VCSH
or VCTS mention there. Showers and a few storms will be possible

NE flow through the period, becoming breezy this afternoon, with
gusts up to 18-20kts, especially along the coast. Winds will

4-5 FT in the Gulf Stream beyond 20 nm. Scattered showers and
isolated lightning storms will persist over the next couple days.
Monday-Wednesday... Occasionally poor boating conditions. High

This Hazardous Weather Outlook is for east central Florida. .DAY ONE...Today and tonight. .THUNDERSTORM IMPACT... Isolated lightning storms are forecast today. Brief gusty winds to 40 mph, occasional lightning strikes, and heavy rain will accompany any stronger storms that develop. .RIP CURRENT AND SURF IMPACT... A high risk of life-threatening rip currents exists at the Volusia and Northern Brevard County beaches, and a moderate risk of rip currents exists at the remaining Central Florida Atlantic beaches. Entering the water is highly discouraged. If caught in a rip current, relax and float. Don't swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help. .COASTAL FLOOD IMPACT... Minor coastal flooding is expected during today's high tide cycles. Low lying streets, yards, and docks could become submerged. Water may reach the dune line or seawalls at our most vulnerable beaches. Never drive your vehicle through salt water. .RIVER FLOOD IMPACT... The Saint Johns River near Astor is forecast to remain in Moderate Flood stage. .DAYS TWO THROUGH SEVEN...Sunday through Friday. Isolated lightning storms are forecast through early next week. Brief heavy rain and gusty winds will accompany any stronger storms. A moderate to high risk of dangerous rip currents will continue at the beaches. A Coastal Flood Advisory remains in effect through Sunday afternoon due to above normal water levels around the times of high tide. This may cause minor inundation of low lying properties near inlets, nearby areas along the Intracoastal Waterway, and adjacent canals. Some docks or sea walls may briefly get overtopped by water. Flooding along the Saint Johns River, particularly at Astor, will continue through the middle of next week. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed today and tonight.
