Area Forecast Discussion
National Weather Service Melbourne FL
937 PM EDT Sun Oct 1 2017

.UPDATE...

...Flooding Impacts Expected to Continue across Brevard County
Overnight...

Convergent shower bands that brought extremely heavy rainfall to
areas from Floridana Beach and Melbourne Beach to Palm Bay and
West Melbourne has shifted northward gradually into late evening
bringing heavy rainfall to central Brevard. A mesonet observation
site in Floridana Beach has reported 10.68 inches of rain since
midnight and still raining. Another mesonet site in Palm Bay has
seen 9.13 inches since midnight with a West Melbourne site
reporting 7.57 inches today. Flash Flood Warning has been reissued
and covers portions of central and southern Brevard counties
through 1130 pm. HRRR suggest strongest convection will shift
south overnight while other guidance suggests Brevard and Indian
River may remain the focus for Atlantic showers bands through the
overnight hours. Radar trends show another primary rain band from
the Cape eastward developing across the Atlantic that should
eventually shift gradually south overnight but will continue
threat for locally heavy flooding rainfall across central/srn
Brevard counties to Indian River county later tonight. Have made
adjustments upward to POPs/QPF in areas that will be focus for
additional onshore moving showers through the night. Flood Warnings
will likely be extended for portions of Brevard county into the
overnight hours.

&&

.AVIATION...
Heavy showers moving onshore from the Atlantic will continue
overnight with highest concentration of showers/isolated storms
from KTIX-KVRB corridor into late tonight. MVFR CIGs and IFR VSBYs
associated with convection. Additional showers will affect KDAB
vcnty and KFPR-KSUA with activity diminishing as it moves inland
toward KSFB-KMCO terminals. Some gradually drying across north FL
into the afternoon should shift most shower chances south of
KISM-KTIX line by afternoon.

&&

.MARINE...
Easterly winds increasing to around 20 knots will allow seas to
build to 5-7 ft nearshore and up to 6-8 ft well offshore late
tonight. No significant changes expected with late evening marine
update. Small Craft will be in effect for all waters past 10 pm.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TONIGHT.

.THUNDERSTORM IMPACT...
Strengthening onshore flow will allow Atlantic showers and
isolated lightning storms to move onshore overnight. Storms will
produce some cloud to ground lightning strikes, but locally heavy
rainfall will be the main hazard producing areas of flooding.

.FLOOD IMPACT...
Bands of showers with heavy rainfall will continue to move onshore
from the Atlantic through the night. Very heavy rainfall amounts
will focus across the southeast Volusia county, Brevard county and
Indian River counties through the late night hours. Additional
areas of flooding are likely with water across roadways and
potentially into some low lying homes and houses near poor
drainage areas. Do not drive into flooded roadways at night.

.WIND AND SEA IMPACT...
Easterly winds up to 20 to 25 knots will build seas to 6 to 9 feet
nearshore and up to 10 to 12 feet offshore late tonight. Small
craft advisories remain in effect.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
The strong ridge of high pressure will produce several more days
of breezy to windy onshore flow. Gusty, onshore moving showers and
squalls are are likely into at least Thursday, especially along
the coast. As seas and surf build through next week, conditions
for boaters and beachgoers will become increasingly dangerous.
Numerous strong rip currents are also likely, and additional
erosion of the already weakened beaches and the dune line may
occur around the times of high tides.

High rain chances will lead to localized flooding or aggravation
of ponding or standing water, especially in poor drainage and low
lying areas, water retention areas, and near larger river basins
such as the St Johns River, which is forecast to only decrease at
a very slow rate.

.SPOTTER INFORMATION STATEMENT...
Spotters should report flooding to the National Weather Service in
Melbourne, law enforcement or local emergency management.
