Excessive Heat Warning Issued for Southwestern U.S.
An Excessive Heat Warning is in effect in a developing situation through 9:00 PM on August 1, 2020. Issued by the Phoenix National Weather Service, the warning covers parts of Arizona, Nevada, and California, including the cities of Phoenix and Las Vegas.
Temperatures are expected to reach up to 50C (122F), which the weather service characterized as "dangerously hot conditions," according to Yahoo News. The elderly, people with certain medical conditions, and individuals lacking access to air conditioning are at heightened risk. In addition, the intense heat, dry weather, and light breeze could create a fire risk.
Advised precautions include staying hydrated, drinking fluids before feeling thirsty, avoiding unnecessary outdoor activities, checking on family and friends, preparing for hot nights, and operating air conditioning "despite financial cost."

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.
