Lee and Collier

Southwest Florida gets a second straight day at a heat index of 112, and for the first time in this run the Lee County forecast office did not write a fresh advisory but simply let yesterday's keep going

What it changes

The number has not moved, and that is the point. For the second morning running both Southwest Florida forecast offices have 112 written into the heat advisories covering Lee and Collier, on the same eight hour window they have used since the middle of last week, 11 a.m. to 7 p.m. Lee is written at a heat index of up to 112 and Collier at 105 to 112. A resident who planned around yesterday can plan around today without changing anything. There is one genuine change, and it sits in the machinery rather than in the air. Every heat advisory this desk has recorded over these counties since late July has been a new product, written fresh in the small hours and given its own number. This morning the Tampa Bay Ruskin office, which covers Lee, did not write a new one. It continued the one already running, and its headline says so in plain words: the advisory remains in effect. The Miami office, which covers Collier, did write a new one. So the two counties are under advisories of different vintage for the first time in this stretch, with identical hours and an identical top of the range. That difference is worth understanding for what it is not. It is not a signal that Lee is in more or less danger than Collier. Lee falls under Tampa Bay and Collier falls under Miami, the two offices number and issue their heat products separately without reference to each other, and a continuation rather than a reissue is a choice about paperwork when conditions have not changed enough to justify redrawing the product. The practical reading is the opposite of dramatic: the forecast has been stable enough for two days that one office saw no reason to start over. The people the back half of that window is aimed at have not changed either. Roofers, landscapers, pool and pressure washing crews, road crews, tradespeople loading trucks at the end of a shift, and anyone whose day does not stop at five. The hottest part of the advisory sits over the middle of the afternoon, and the instruction attached to both products is the plainest version either office writes: drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Both offices rate the product as moderate in severity and both had it written before half past one in the morning, so nobody in Fort Myers, Cape Coral, Bonita Springs, Estero, Lehigh Acres, Naples, Marco Island, Immokalee or Golden Gate has to wait on a mid-morning enlargement to know what today looks like. One thing this does not tell you is how long the run has left. A continuation carries no forecast of its own beyond 7 p.m. this evening, and the next advisory, or the absence of one, will be written tonight in the same small hours as this one.
