The National Weather Service Tallahassee FL raised a heat advisory to an Extreme Heat Warning on Monday, Aug. 17, 2026, for portions of Big Bend and Panhandle Florida, according to the official alert record issued by that office and published in the National Weather Service raw text archive.
The record states the Extreme Heat Warning runs from 11 AM EDT /10 AM CDT/ to 8 PM EDT /7 PM CDT/ Monday, with dangerously hot conditions and heat index values up to 115 expected. Under the earlier Heat Advisory, in effect until 8 PM EDT /7 PM CDT/ this evening, heat index values reach up to 111.
The alert record lists 15 zones: Inland Bay, Calhoun, Inland Gulf, Inland Franklin, Gadsden, Leon, Inland Wakulla, South Walton, Coastal Bay, Coastal Gulf, Coastal Franklin, Coastal Jefferson, Coastal Wakulla, Northern Liberty and Southern Liberty.

On impacts, the record states that heat related illnesses increase significantly during extreme heat and high humidity events, and that hot temperatures and high humidity may cause heat illnesses.
The precautions in the record direct residents to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. It warns against leaving young children and pets in unattended vehicles, saying car interiors will reach lethal temperatures in a matter of minutes. Residents are told to wear lightweight and loose fitting clothing, to limit strenuous activities to early morning or evening, and to act at the first symptoms of heat exhaustion and heat stroke. To reduce risk during outdoor work, the record notes, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency, the record says: call 9 1 1.
The office advises the public to stay cool, stay hydrated and stay informed, and to monitor the latest forecasts and warnings for updates.

How we work
This site models an investigative reporter rather than a wire desk. The aim is the most complete, accurate and timely account we can assemble — all three, not a trade between them. Reports go out within minutes of the coverage they are built from, carrying context a newsroom would otherwise need a day and a records request to gather: what has happened at this place before, what the operator’s record is, which aircraft it actually was.
Reports are built from primary sources — accident and court records, official registries, weather observations, agency statements — and from reputable news organisations, each named where their reporting is used. Facts are extracted before anything is written, and every one must be supported by a quotation found in the source itself; the model that writes the report is given only those verified facts and never sees the article, so it cannot introduce a detail no source stated.
Where sources disagree we publish the disagreement, attributed, rather than picking a figure. Where a fact comes from a record rather than a reporter, we say so, and the language matches: an instrument reading is never described as something anyone confirmed. Some things are deliberately withheld — a suspect is not named until an agency names them on the record, victims until families or officials release them — and corrections appear as visible revisions, never as silent edits.
None of that makes a report true. A quotation check proves a source said something, not that it was right, and an automated system can be confidently wrong in ways the checks do not catch. If something here is wrong, the feedback above is how it gets found. The full methodology, including what we refuse to publish.
