The National Weather Service put a severe thunderstorm warning over west central Collier at 4.05 p.m. with 60 mph gusts, on top of a flood advisory that runs until 5.45 p.m. with water over roadways from Naples to Marco Island

Update, 4.30 p.m. The severe thunderstorm warning was continued at 4.21 p.m., still running to 4.30 p.m. and still carrying 60 mph gusts and hail up to three quarters of an inch. The storm had moved again and sat over North Naples, near Bonita Springs, moving northwest at 10 mph.

That put it on the county line, and at 4.23 p.m. the Tampa Bay Ruskin office placed coastal and inland Lee County under a special weather statement of its own until 5 p.m., with gusts of 40 to 50 mph from Cape Coral through Fort Myers to Estero. It is the first Lee alert of the afternoon. The county wide flood advisory here is unaffected and still runs to 5.45 p.m.

Update, 4.22 p.m. The weather service upgraded this storm to a severe thunderstorm warning at 4.05 p.m., a level above the statement described further down. The warning covers west central Collier County and runs until 4.30 p.m. unless the office extends it.

At 4.05 p.m. the storm was over Vineyards, near Naples, moving northwest at 10 mph. The hazard is 60 mph wind gusts and hail up to three quarters of an inch, both radar indicated, and the stated impact is damage to roofs, siding and trees. That is a step up from the 45 to 50 mph gusts carried by the earlier statement.

The instruction attached to the warning is to move to an interior room on the lowest floor of a building. The office adds that torrential rainfall is occurring with this storm and may lead to flash flooding, and repeats that drivers should not go through flooded roadways.

The locations named in the warning are Naples, Golden Gate Estates, Naples Park, Belle Meade, Naples Manor, Golden Gate, East Naples, Lely Resort, the West Toll Gate on Alligator Alley, Vineyards, North Naples, Pelican Bay, Lely, Rookery Bay Aquatic Preserve and Quail Creek Estate.

The county wide flood advisory below is unaffected by the upgrade and still runs until 5.45 p.m.

The National Weather Service office in Miami issued a flood advisory for Collier County at 3.52 p.m. on Wednesday. It runs until 5.45 p.m.

Doppler radar had recorded between two and three inches of rain over the advisory area by the time it was issued, and the office expects a further one to two inches on top of that.

The advisory says minor flooding is ongoing or expected to begin shortly, with water over roadways and ponding in urban and poor drainage areas either occurring or imminent.

The locations the office named are Naples, Marco Island, Golden Gate Estates, the West Toll Gate on Alligator Alley, Golden Gate, Lely Resort, Naples Manor, Vineyards, East Naples, Belle Meade, North Naples, Orangetree, Lely, Fiddlers Creek and Rookery Bay Aquatic Preserve.

A separate special weather statement covers the wind. Issued at 3.47 p.m. for coastal and inland Collier, it has meteorologists tracking a strong thunderstorm over Golden Gate Estates moving northwest at 15 mph, with radar indicated wind gusts of 45 to 50 mph. The stated impact is that gusty winds could knock down tree limbs and blow around unsecured objects. That statement expires at 4.30 p.m.

An earlier statement, issued at 3.26 p.m. and running to 4 p.m., tracked the same storm over Marco Island Airport moving northwest at 10 mph with the same gust hazard. The two together put the storm's track from the coast near Marco Island inland toward the Estates through the afternoon.

The advisory is rated Minor severity. That is the level for nuisance street flooding rather than water reaching living space, and no evacuation order, shelter opening or county emergency declaration accompanies it.

Neither of the two consequences that usually follow a storm of this kind had appeared by 3.56 p.m. Collier County had 243 customers without power against 283,032 tracked on the poweroutage.us county page, which is an ordinary number for a weekday afternoon.

The Florida Highway Patrol incident board carried no storm-related closure in the county. Its only Collier entries were the fatal crash at Davis Boulevard and Heritage Trail from Wednesday morning, marked roadway clear, and a construction lane closure on the Collier Boulevard ramp to I-75 southbound dated Tuesday.

That board covers state roads, which means I-75, US-41 and the state routes. County and city streets are sheriff calls and do not appear on it, so an empty result there is not an all clear for the neighbourhood streets most likely to pond.

The instruction the weather service attaches to a flood advisory is the same one it attaches to every one of them. Do not drive through a flooded roadway.

The state road board was checked again at 4.21 p.m., after the warning was issued. It still carried no storm related closure in Collier. The two county entries were the same as before, the Davis Boulevard fatality marked roadway clear and the Tuesday construction closure on the Collier Boulevard ramp. The power figure could not be refreshed at that time because the poweroutage.us county page was returning a bot challenge rather than data, so the 243 customers above remains a 3.56 p.m. reading and not a current one.

No alert was in effect for Lee County at 4.15 p.m.
