Area Forecast Discussion
National Weather Service Melbourne FL
422 PM EDT Sun May 27 2018

...Risk of Flooding Will Continue Across Space and Treasure
Coasts...

.DISCUSSION...
As of 4:00 PM, the center of Alberto sits roughly along the same
latitude as Melbourne (approximately 300 miles to its west). Mean
southerly flow through much of the troposphere continues to draw
a deeply moist environment over the eastern half of the peninsula,
while drier air is intruding in the mid levels closer to the
system's circulation.

For the rest of this evening and tonight, some of that dry air
will bleed overhead, leading to a NW-SE gradient in moisture (and
subsequently PoPs). Convergent outer rain bands east of Alberto
will provide the best opportunity for precipitation, especially
across the Treasure Coast in the vicinity of the deepest moisture
and where both the HRRR and other mesoscale models indicate
banded structure to overnight convection. With that in mind, will
maintain the highest PoPs south and east of a line connecting
Titusville to Lake Kissimmee and keep the Flood Watch up for
Brevard, Indian River, Saint Lucie, Martin, and Okeechobee
counties. Additionally, the tornado threat is subsiding, as
increasingly uni-directional winds in the lowest levels will keep
strong wind gusts as the main threat from showers this evening.

Monday...Precipitable water output from both the GFS and ECMWF
indicate the continued presence of a moisture gradient; however, as
Alberto makes landfall and continues to pull away from the area,
moisture that was shunted to our east will migrate back over the
area. Given the presence of drier air aloft initially (at least
across northern and western sections), expect a little more
heating and delayed start to convection north of the Treasure
Coast and Okeechobee County. However enough moisture will still
exist for numerous showers and storms to develop across the area
through the afternoon, with rain chances ranging from 60 percent
west of I-4 to 70 percent for the rest of the area. Heavy rainfall
and localized flooding issues will continue to be a concern with
any heavier showers and storms that move over the same area. A
Flood Watch will remain in effect for Brevard, Indian River, Saint
Lucie, Martin, and Okeechobee counties where overall the deepest
moisture will reside.

Tue-Fri...Alberto will weaken as it continues northward after
landfall along the northern Gulf Coast. However, a moist airmass of
2+ inch PW values will persist across the area through late week.
This will continue elevated rain chances through Friday, ranging
from 60-70 percent on Tuesday to 50-60 percent through Friday.
Greatest coverage of showers and storms will occur during the
afternoon hours, with locally heavy rainfall still being a concern.
Highs will range from the mid-upper 80s, with low 90s possible
across portions of the area on Friday.

&&

.AVIATION...
Gusty SE gradient winds up to 30 knots will diminish with sunset.
Have added TEMPO groups for MVFR CIGs/VSBYs in TSRA from MLB-SUA
late this afternoon as cluster of storms lifts N/NE from Lake
Okeechobee. Will handle the remaining terminals with VCSH. Shower
coverage should decrease overnight most areas except there is
potential for persistent SHRA from FPR-SUA past 00Z. On Monday,
winds will be southerly and breezy with frequent gusts around 25
knots. Numerous showers/storms expected aft 18Z.

&&

.MARINE...
Tonight...Hazardous marine conditions will continue overnight as
tight pressure gradient between Alberto and high pressure over the
western Atlantic continues. South winds 20 to 25 knots, with
occasional gusts to gale force offshore continue. Guidance
indicates winds will subside some toward daybreak, but still
remaining around 20 knots. Seas 5 to 7 near the immediate coast,
increasing up to 8 to 9 feet offshore. Small Craft Advisory
remains in effect.

Mon...Poor to hazardous boating conditions look to continue into
Memorial Day. SCA has been extended for the offshore waters through
Monday evening for southerly winds around 20 knots and seas up to 7
feet. Nearshore, winds will range from 15-20 knots with seas 4-6
feet.

Tue-Thu...Winds and seas will then continue to gradually improve
through mid week, with southerly winds decreasing to 10-15 knots and
seas falling to 5 feet or less.

1045 AM EDT Sun May 27 2018

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
Squalls containing heavy rain and gusty winds will move northward
across the region through the afternoon. Occasional lightning
strikes and wind gusts up to 50 mph will occur in the stronger
storms. A few storms may contain damaging wind gusts near 60 mph.
Wind shear will support rotating cells and potential for isolated
tornadoes into early this evening. The threat for severe weather
should decrease overnight.

.FLOOD IMPACT...
Conditions remain favorable for heavy rainfall and localized
flooding where any persistent rainbands can set up. Some locations
are experiencing saturated soil due to heavier rains since last
week. Anyone planning travel today should not try to drive through
water of unknown depth on roadways. A Flood Watch Continues through
Monday.

.HIGH WIND IMPACT...
Southeast winds near 20 mph will occasionally gust up to 35 mph away
from showers and storms. This will produce hazardous boating
conditions on the intracoastal waters and inland lakes. A Lake Wind
Advisory is in effect.

.RIP CURRENT IMPACT...
Strong winds and building surf will occur today as Alberto moves
northward over the eastern Gulf of Mexico. Rough surf and strong
currents will be present. Bathers are advised against entering the
water to any floating depth. Do not swim alone.

.MARINE THUNDERSTORM GUST IMPACT...
There is a high likelihood of wind gusts around 35 to 40 knots
over the Atlantic waters as numerous squalls move north across the
marine area as well as over larger lakes and bodies of water of
central Florida.

.WATERSPOUT IMPACT...
Sufficient low level wind shear will support waterspouts over the
adjacent Atlantic waters and large lakes of east central Florida.

.WIND AND SEA IMPACT...
Hazardous boating conditions occurring with southeast winds 20 to 30
knots with occasional gusts to gale force offshore. A Small Craft
Advisory is in effect areawide.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
Abundant tropical moisture will continue across the region and a
few periods of showers and lightning storms are expected through
at least Memorial Day.

The main hazard will be a possibility of widespread heavy rainfall,
causing flooding to become more of a concern. Dangerous lightning
strikes, gusty winds will be possible. Boating and beach conditions
will remain hazardous into Monday as well.

.SPOTTER INFORMATION STATEMENT...
Spotters should monitor the weather and self activate if necessary.
Please report rainfall amounts of 3 inches or greater to the National
Weather Service in Melbourne.

...A STORM WITH THE POTENTIAL OF DEVELOPING FUNNEL CLOUDS WILL AFFECT
EASTERN MARTIN COUNTY...

At 318 PM EDT, a strong thunderstorm was located 7 miles northwest of
North County Airport, or 12 miles southeast of Indiantown, moving
north at 25 mph.

Winds in excess of 40 mph are possible with this storm.

Locations impacted include...

short duration and winds generally less than 60 mph which can cause
minor damage and injuries in its direct path. If this trend
continues, a tornado warning may be issued shortly. Stay tuned to
NOAA weather radio and local media for additional updates and
possible warnings.
