Collier County

What it changes

If you are in Collier County today, the National Weather Service wrote a heat advisory for you at twenty to three this morning and it runs from 11 a.m. to 6 p.m., with a heat index forecast of up to 110. The index is what the heat and the humidity feel like together rather than the air temperature, which is why a forecast high in the middle nineties produces a number that looks fifteen degrees higher. The service rates the event moderate in severity and likely in certainty, and its own instruction is short and worth following literally: drink plenty of fluids, stay in an air conditioned room, stay out of the sun, and check on relatives and neighbours. The product adds that outdoor activity should be limited where possible to early morning or evening, that lightweight and loose fitting clothing helps, and that the right response to the first symptoms of heat exhaustion is to act rather than to push through. In a county where roofing, landscaping, construction and lawn crews start at first light and are still out at four in the afternoon, the seven hour window in the middle of that working day is the whole point of the advisory. Two details are worth keeping straight, because both of them cut against the way this kind of alert usually gets read. The first is that Lee County is not in it. Three separate Lee zone queries came back empty on the same reads that returned this product, and that is not an oversight: Collier sits under the Miami forecast office and Lee sits under Tampa Bay Ruskin, and the two write their heat products independently. A Naples resident and a Fort Myers resident will feel much the same afternoon today, but only one of them has an issued advisory, and a headline about one county should not be read across the county line in either direction. The second is that Collier is carried in its own product this time. On July 30, when this site last reported one of these, the Collier zones were bundled into a single Miami advisory alongside seven zones across Palm Beach, Broward and Miami Dade. Today the Miami office split them: Collier has one product and the ten southeast coast zones have another, sharing the same event number and the same hours. Nothing about the hazard changed with the split, and nothing should be read into it, but it is the reason the statewide count looks the way it does. Florida has exactly three active weather alerts this morning across the entire state, and all three are heat advisories: this one, the southeast coast one, and a Melbourne office product covering Okeechobee and Martin that runs two hours longer. There is no storm anywhere in it. The National Hurricane Center states plainly that there are no tropical cyclones in the Atlantic, the eastern Pacific or the central Pacific right now, so nothing in the tropics bears on the week. What comes next is forecast rather than issued, and belongs to the meteorologists who wrote it rather than to the weather service. WINK News, in a piece by Oceana Hayden and David Nazario, describes a dome of high pressure moving into the Southeast that ends the wet pattern of recent weeks, with Saharan dust reinforcing the building heat through the middle of the week, rain chances falling away and temperatures pushing well into the nineties for a stretch of days. Their read is that further heat advisories are possible later in the week. Treat that as the shape of the week rather than as a promise, and treat today's product, which is issued and specific, as the thing to plan around. The one wrinkle in an otherwise dry forecast is this afternoon: the same newsroom expects scattered storms between roughly two and six, which is inside the advisory window, so a brief downpour and a 110 index are not mutually exclusive today. On the roads, the state dispatch board carried no crash in either Lee or Collier when it was read at half past four this morning. The only Southwest Florida entries on it are the two standing construction closures on Collier Boulevard at the Exit 101 interchange in Naples, southbound with two right lanes closed and northbound with the left lane closed, both of which have been on the board since Sunday morning. That board covers state roads only, so it is silent about county roads and city streets rather than clear about them.

The National Weather Service office in Miami issued a Heat Advisory at 2.38 a.m. on Monday, August 10, covering Coastal Collier and Inland Collier counties. It takes effect at 11 a.m. and runs until 6 p.m. the same day, and it forecasts heat index values of up to 110.

The service rates the event moderate in severity, likely in certainty and expected in urgency. Its own headline on the product reads that the advisory is in effect from 11 a.m. this morning to 6 p.m. this evening for Collier County.

The product is marked NEW rather than a continuation, carrying event number 0026. A heat advisory is written fresh each morning because the hazard lapses overnight, so a new event number is the normal pattern rather than a sign of anything unusual.

No Lee County zone appears in it. Three separate queries of the Lee zones returned nothing active at all shortly after half past four on Monday morning, on the same reads that returned products elsewhere in the state. Lee falls under the Tampa Bay Ruskin forecast office rather than Miami, which is why heat products for the two counties are issued separately and do not track one another.

Collier is in a product of its own this time. On July 30, the last of these this site reported, the Collier zones shared a single advisory with seven zones across Palm Beach, Broward and Miami Dade. Monday's Miami advisory for the ten southeast coast zones carries the same event number and the same hours but is a separate product, with Collier standing alone in its own.

Across the whole of Florida there are three active weather alerts this morning, and all three are heat advisories. The third is from the Melbourne office and covers Okeechobee and coastal and inland Martin, running until 8 p.m. rather than 6.

There is no tropical activity behind any of it. The National Hurricane Center states that there are no tropical cyclones in the Atlantic, the eastern Pacific or the central Pacific at this time.

The instruction in the product is the service's own: drink plenty of fluids, stay in an air conditioned room, stay out of the sun, and check up on relatives and neighbours. It adds that people outside should take extra precautions, wear lightweight and loose fitting clothing, try to limit strenuous activity to early morning or evening, and act on the symptoms of heat exhaustion and heat stroke rather than work through them.

The week ahead is a forecast rather than an issued product. WINK News meteorologists Oceana Hayden and David Nazario reported on Sunday that a dome of high pressure is moving into the Southeast, ending the wet pattern of recent weeks, with Saharan dust reinforcing the heat through the middle of the week and rain chances falling away. Their piece says the weather service may issue further heat advisories by late week.

The same newsroom expects scattered storms in Southwest Florida between roughly two and six on Monday afternoon, which falls inside the advisory window, and gives a high of 94 for Fort Myers against an overnight reading of 77.

Early voting is open in Collier and Lee through August 15, and the property tax amendment is not the thing on this ballot

The crash the Florida Highway Patrol had open on Interstate 75 northbound at the Palm Beach Boulevard interchange in Fort Myers carries a clearance stamp of 8.01 on Sunday evening, and the entry has since dropped off the state dispatch board altogether
