NWS Warns High Temperatures and Humidity May Cause Heat Illnesses
High temperatures and high humidity may cause heat-related illnesses, according to official records from the National Weather Service Jackson MS. The agency highlighted the health risks as part of an Extreme Heat Warning covering portions of southeast Arkansas, northeast Louisiana, and much of Mississippi. The warning took effect on August 16, 2026, at 2:15 AM CDT and is scheduled to end on August 17, 2026, at 8:00 PM CDT. Official records state that dangerously hot conditions will bring heat index values up to 115 across 30 zones. Official precautions instruct people to drink fluids, remain in air-conditioned spaces, stay out of the sun, and check on relatives and neighbors. Children and pets should not be left in unattended vehicles, as interior temperatures will become lethal in minutes. The Occupational Safety and Health Administration recommends frequent rest breaks in shaded or air-conditioned areas for outdoor workers, and official guidance emphasizes calling 9 1 1 immediately if heat stroke occurs.

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.
