Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.

Area Forecast Discussion
National Weather Service Melbourne FL
401 PM EDT Sun May 9 2021
.DISCUSSION...
Evening-Mon...Cloud coverage has been slow to develop and has
been confined to the coastal counties through earlier this
afternoon. This in part as the ridge extending from the central
Atlantic towards the FL peninsula retreated a bit east this
afternoon and the flow became SSE and moisture was limited (around
1 inch of PWAT from the 15z Cape sounding). However, both coasts
sea breezes will develop and should collide early this evening
across the interior from Lake county down to west of Lake
Okeechobee. Rain chances were kept to 15-20 % through this evening
for southern Osceola, Okeechobee counties. Then if any of this
activity that develops survives, it could push towards the
Atlantic waters but confidence is low and we could update the
forecast this evening to clear it. Otherwise, low temps tonight
will drop to the upper 60s to lower 70.
Ridge will continue over central FL on Monday and a similar
scenario is expected with a southerly wind in the morning then
shifting from the SE along the coast in the afternoon as the sea
breeze develops. A collision of both coasts' sea breezes could
happen later in the afternoon south of Okeechobee which could push
some storm activity towards Okeechobee and Osceola later in the
afternoon. Elsewhere, light showers coming with the southwest flow
in the afternoon could reach the local area as well. Highs will
be toasty, reaching the lower 90s across the interior and upper
80s/near 90 in the immediate coast.
Monday Night-Tuesday...Surface high pressure drifting further
eastward into the Atlantic, as upper-level flow becomes increasingly
zonal. Dry conditions expected Monday night after afternoon showers
and thunderstorms drift offshore during the evening hours. Tuesday,
increasing moisture is expected to be funneled to the area from the
Caribbean due southerly flow on the far western periphery of high
pressure over the west-central Atlantic. PWATs increasing to 1.75+"
will generate a chance of showers and isolated thunderstorms Tuesday
afternoon. Highest chances look to be over the central peninsula
along the seabreeze collision, before showers and storms drift
eastward towards the Atlantic waters during the evening hours.
Temperatures Tuesday morning in the upper 60s to low 70s area-wide.
Then, becoming hot for the afternoon, with highs increasing to the
low 90s across the interior and upper 80s along the coast. Winds
will be generally around 5mph or less for much of the day across the
interior, before the sea breeze generates along the coast and
pushes inland in the afternoon.
Wednesday-Saturday (modified previous)... An increase in rain
chances will begin on Wednesday, as a frontal boundary parks over
northern Florida. Scattered showers and isolated storms will be
possible areawide, especially in the afternoon/early evening hours,
with daytime heating and sea breeze interactions. The front will
slowly sag further southeast into the end of the week, which means
the best chance for rain will be Thursday into Thursday night, with
numerous showers and scattered thunderstorms expected during the
afternoon. Precipitation will slowly come to an end from the
northwest to southeast Friday, once the front finally moves
southeast of Florida. Drier conditions expected Saturday and Sunday,
but a slight chance of showers and thunderstorms can't be ruled out
along the far southern Treasure Coast. Highs will stay in the upper
80s to low 90s with lows in the upper 60s to low 70s on Wednesday
before moderating due to onshore flow towards the end of the week.
Rain and cloud coverage will keep temperatures slightly cooler
through the end of the forecast period, with highs mainly in the low-
to-mid 80s and lows in the low 60s to low 70s.
&&
.AVIATION...
VFR will prevail tonight and Mon morning. With the exception of a
few showers/VCTS that could reach KVRB-KSUA around midnight but
confidence on this continues to decrease. Otherwise, gusty winds
for coastal sites should decrease this evening with winds
remaining generally from the south with FEW-SCT 030-040.
&&
.MARINE...
Evening-Mon...As a low pressure exits the northeast U.S. tonight
and the ridge stays across the FL peninsula, the wind gradient
will tighten along the southeast U.S. coast. Winds will slightly
increase tonight across the local waters: to near 20 kt east of
Volusia where a Small Craft Advisory is in effect through 4 am
while if navigating on the waters east of Brevard, small craft
should exercise caution. Seas east of Volusia will build to 3-4 ft
tonight but will quickly subside to 2-3 ft on Mon. South of
Volusia, seas will range between 2-3 ft tonight and tomorrow.
Wind gradient will relax late tonight and Mon morning, keeping
winds from the south 10-15 kt.
Monday night-Friday...Southerly winds remaining around 10-15kts
overnight Monday, with seas 2-3ft. Winds will relax on Tuesday, with
south-southeasterly winds from 5-10kts developing in the afternoon
along the sea breeze. This pattern will continue through Wednesday,
before a front approaches the area on Thursday. Then, winds becoming
northerly into Friday, but remaining around 10-15kts. Seas 1-3ft
through mid-week, then increasing as winds veer, becoming 4-6ft into
Friday. Shower and thunderstorm chances continuing through the
period, with activity moving from the interior to the coast during
the evening hours. Chances then increasing into the end of the week,
as the aforementioned front passes southward through the local area.
&&
.FIRE WEATHER...
Monday...Wind flow will be from the south and southwest tonight
and Monday morning. The east coast sea breeze will develop on Mon
afternoon pushing westward, shifting winds along the coastal
counties from the southeast, which will also increased moisture
over the region through the start of the workweek. Minimum RH
values will be in the 40-55 percent range on Mon with ERC values
above 27 across some of our local counties.
