What happened

The episode as NWS MFL wrote it up.

Drought conditions continued across South Florida into mid April, allowing for the rapid spread of two wildfires, the 30th Avenue Fire, and Frangipani Fire, that started in the Golden Gate Estates area of eastern Naples. Given the proximity of the fires two each other, a large mandatory evacuation area was ordered for the region, from the south side of Golden Gate Boulevard south to I-75, and from Collier Boulevard east to Wilson Boulevard. Additional voluntary evacuations were ordered for homes south of Golden Gate Parkway from Tropicana Boulevard east to Collier Boulevard in Golden Gate City, affecting over 7000 residents. The wildfires resulted in the closures of numerous roads in the area, as well as schools, business, and parks. The Frangipani Fire was contained within 24 hours, however the 30th Avenue Fire was not able to reach containment until 25 April.

.UPDATE...
The 12Z MFL sounding showed sufficient moisture from the surface
to around 800 mb with a capping temperature inversion and dry air
aloft. Latest surface analysis displayed a 1025 mb surface high
sitting stagnant over southeast CONUS. This feature will
responsible for maintaining breezy easterly winds today across
South Florida, forecast sustained around 15 mph across the
eastern peninsula and 10 mph further west. After the loss of
daytime heating, winds in the interior should dwindle. Current
radar trends show light showers moving westward from the Atlantic
over portions of the east coast metro region. Short term models,
including the HRRR and WRF models prog this activity to shift over
the interior during the late morning and towards the Gulf Coast
by afternoon. Have updated PoPs to reflect this trend. Otherwise,
all other variables appear on track.

.PREV DISCUSSION... /issued 805 AM EDT Thu Apr 20 2017/

AVIATION...
Stagnant surface high pressure to the north will maintain breezy
easterly winds, around 15 KT, for the east coast TAF sites aft
20/1500Z. By this evening, these winds should decrease slightly,
but remain easterly around 10 KT overnight. There will be sct low
clouds with bases 3000 ft msl through the period with a few light
showers, but not confident enough to include VCSH in the TAFs
this afternoon. Not expecting a gulf sea breeze, as the easterlies
should be too strong.

.High Risk of Rip Currents east coast beaches of South Florida
through this evening...

.Fire Weather Watch issued for western interior areas Friday...

DISCUSSION...

TODAY THROUGH FRIDAY...
High pressure over the southeast United States will remain nearly
stationary today into Friday keeping the breezy easterly wind
flow in place. Drier air over the western Atlantic waters will
also be working wester into South Florida today and remain over
the area through Friday. Therefore, the isolated showers that have
been occurring over the east coast metro areas and the adjacent
coastal waters early this morning will shift to the western areas
this afternoon. The weather will then be dry for tonight into
Friday over all of South Florida.

SATURDAY AND SUNDAY...
The high will weaken while moving southeast into the western
Atlantic this weekend, as low pressure moves southeast from the
northwest United States into the central United States. This will
cause wind flow to become more southerly over South Florida this
weekend and bring in some moisture to the area late this weekend.
Therefore, there will be low POPs over the interior areas on
Saturday before increasing Sunday. Rest of South Florida should
remain dry on Saturday before a slight chance of showers is
introduced for Sunday.

The east and west coast sea breezes will also develop on Sunday
and push inland and possibility collide with the Lake breeze.
These boundaries and the increase in moisture will help to
generate a few thunderstorms over the Lake Okeechobee region
Sunday afternoon. Therefore, a slight chance of thunderstorms have
been added for the Lake Okeechobee region for Sunday afternoon.

EXTENDED FORECAST...
The latest long range models are now showing the low to move
southeast from the Central United States into the Southeastern
United States early next week instead over Northern Florida,
before moving into the Western Atlantic waters by middle of next
week. A cold front associated with the low will also be moving
southeast and through South Florida late Monday.

The winds over South Florida will be southerly on Monday before
going northerly for Tuesday into Wednesday. This will allow for
the moisture to remain over South Florida for Monday before drier
air work into the area from the north for Tuesday into Wednesday.
Therefore, scattered showers and even a few thunderstorms will be
possible on Monday especially over the northeastern areas before
going dry for Tuesday into Wednesday.

MARINE...
Breezy easterly winds will continue over most of South Florida
local waters today into tonight, before slowly decreasing to less
than 15 knots this weekend while slowly swinging to an southerly
direction. The seas will remain below 6 feet in both the Atlantic
and Gulf waters through this weekend. Therefore, an SCEC will
continue for the Atlantic, offshore Gulf, and Biscayne Bay waters
through tonight for the wind speeds.

BEACH FORECAST...
The breezy easterly wind flow along with low tide today will
keep the treat of rip currents along the east coast beaches of
South Florida. Therefore, the High Risk of Rip Currents will
continue along the east coast beaches of South Florida through
this evening.

FIRE WEATHER...
The relative humidity today will be in the 40s over most of South
Florida, except for the western interior areas of South Florida
where it could get down to around 40 percent for an hour or two
this afternoon. The 20 foot winds will also be near 10 mph this
afternoon over all of South Florida. At this time, the confidence
is low to issued a Red Flag Warning for the western interior areas
of South Florida, and will let the day shift take a closer look
to see if a short fuse warning is needed.

Must drier weather will be working into South Florida on Friday
from the east allowing for the relative humidities to fall into
the mid to upper 30s over the western areas of South Florida.
The 20 foot winds will also be around 10 mph over this area on
Friday. Therefore, a Fire Weather Watch has been issued for the
western interior areas of South Florida for Friday.

Property damage
$3.5 million
Reported by
Emergency Manager
Coordinates
26.099, -81.381 (the zone’s center; the record gives no point)

The 30th Avenue wildfire was first reported during the afternoon hours on April 20 in the Golden Gate Estates area of eastern Naples in Collier County. This fire, in combination with the nearby Frangipani Fire reported later that afternoon, necessitated the evacuation of a large area of the the Golden Gate area of Naples, as well as numerous road, school, and business closures. The unofficial cause of the fire was a lawn mower that hit a rock that sparked and ignited the very dry vegetation.

Nine homes were destroyed in the fire, most located in the areas of Inez and Smith Roads, and Guevara Avenue. An additional abandoned home on the west side of 32nd Avenue SE, off of Everglades Boulevard was also destroyed. American Farms located off Brantley Boulevard and Inez Road sustained an estimated $1.1 million in damage. Total damage estimates were provided by the Florida Forest Service.

One man was injured while trying to protect his property. He was taken to the hospital with second-degree burns over 18 percent of his body.

Over an inch of rain fell on the fire on April 22 and 23, which helped increase the containment on the fire. The evacuation orders were lifted during the afternoon hours of April 23 as containment increased for the fire.
