Area Forecast Discussion
National Weather Service Melbourne FL
846 PM EDT Wed Oct 11 2017

.UPDATE...
GOES-16 water vapor imagery combined with the most recent RAP
analysis indicates a significant punch of low- to mid-tropospheric
dry air advecting across the area. As a result, radar is nearly
void of returns this evening, save for an isolated shower or two
and some weak convergent signatures over the marine waters.
Moisture in association with a wave over the Bahamas will build
across our southeastern zones late tonight, so will maintain a low
chance for showers over portions of the Treasure Coast waters as
well as Martin and St. Lucie counties closer to sunrise.

&&

.AVIATION...
Generally VFR with northeast winds increasing after sunrise
Thursday. Building moisture through the day on Thursday will
support an increased coverage of showers, especially KVRB-KSUA
corridor.

&&

.MARINE...
Tonight/Thursday...ENE/NE winds approaching 10-15 kts with 15-19
kts offshore/south of Sebastian Inlet. Seas building to 3-5 ft
nearshore and 5-6 ft offshore overnight, up to 7 feet by Thursday
afternoon. Cautionary statements in effect for the offshore
marine legs tonight and will likely be needed over the nearshore
waters on Thursday.

&&

.HYDROLOGY...Moderate to Major flooding continues along the upper
and middle St. Johns River basin. Limited rain chances through mid
week will allow for river levels to remain fairly steady, or show
very slow decreases through this period. Higher rain chances are
expected From late Thursday or Thursday night through this weekend.
Difficult to pin down rain amounts, however any locally heavy
rainfall over the basin will aggravate standing water concerns and
temper the slow decline of water levels.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.RIP CURRENT IMPACT...
An east swell at the beaches will contribute to a moderate risk
for rip currents today. Remember to swim near a lifeguard. 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.

.WIND AND SEA IMPACT...
East to northeast winds to around 15 knots offshore will build
seas to 5 to 6 feet across the offshore waters tonight. Small
craft operators should exercise caution if venturing offshore
after sunset.

.RIVER FLOOD IMPACT...
Major to moderate flooding continues along the the upper and
middle St. Johns River basin. Limited rain chances through
Thursday will allow for river levels to remain fairly steady, or
show very slow decreases through this period.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
Onshore winds and elevated moisture levels will increase shower
and thunderstorm chances for late week and over the upcoming
weekend. A tightening pressure gradient will also support
moderate onshore winds and building seas across the Atlantic
leading to poor boating conditions on the open Atlantic for small
craft.

A lingering swell over the waters will keep a moderate risk of rip
currents along area beaches through much of the week.

.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed today.
