Extreme Heat Warning Takes Effect 11 a.m. Tuesday for Mobile, Pensacola and Gulf Coast Counties
The National Weather Service office in Mobile, Alabama, has issued an Extreme Heat Warning that begins at 11 a.m. CDT Tuesday, Aug. 18, 2026, for coastal Alabama and Northwest Florida, including Mobile, Pensacola, Gulf Shores and Destin. The warning is not in effect at the time of writing; it starts Tuesday morning, according to the Extreme Heat Warning product issued by that office and carried in the Weather Service's raw text product feed.
When it runs: the same product puts the warning in effect from 11 a.m. CDT Tuesday until 8 p.m. CDT Tuesday, Aug. 18, 2026 — a nine-hour span through the hottest part of the day. In the product's own words: "For the Extreme Heat Warning, from 11 AM to 8 PM CDT Tuesday." After 8 p.m. CDT Tuesday the Extreme Heat Warning is no longer in effect. A separate Heat Advisory in the same product runs, as the office puts it, "until 8 PM CDT this evening."
The warning covers 7 zones. In Alabama: Baldwin Central, Baldwin Coastal, Mobile Central and Mobile Coastal counties. In Florida: Escambia Coastal, Okaloosa Coastal and Santa Rosa Coastal counties. Cities named in the product include Mobile, Bayou La Batre, Grand Bay, Daphne, Spanish Fort, Fairhope, Foley, Orange Beach, Gulf Shores, Fort Morgan, Perdido Bay, Pensacola, Ensley, Pensacola Beach, Fort Pickens, Gulf Breeze, Navarre, Bagdad, Fort Walton Beach, Destin, Niceville, Valparaiso, Eglin AFB, Seminole and Wright.
For the Heat Advisory, the product gives heat index values up to 112. For the Extreme Heat Warning, it gives dangerously hot conditions with heat index values up to 115 expected.
The National Weather Service 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 office's precautions, as written in the product: drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke. To reduce risk during outdoor work, 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 — call 9 1 1.
The alert carries the National Weather Service headline: EXTREME HEAT WARNING IN EFFECT FROM 11 AM TO 8 PM CDT TUESDAY.

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.
