The CDC HeatRisk dashboard and the CDC Heat & Health Tracker both returned planned-maintenance pages, while NWS HeatRisk remained fetchable with green/yellow/orange/red/magenta categories and definitions. [1]

CDC provides the source record; no verified same-session X post is attached, so the article treats the source date as the evidence. [2]

The reader task is narrow: keep the source date in view, and do not let a summary substitute for the document, label, count, schedule, method, product name, lot number, public tally, governing line, affected place, or household action that can actually be checked. [1] [2] [3]

That is enough for a brief because the useful news is practical: CDC supplies the record, no verified same-session X post is attached, and the public value is knowing exactly what to verify next before the story becomes another generic warning, market slogan, or institutional talking point detached from the person who has to act.

If the next update changes the product, source date, public count, schedule, vote, measurement method, named actor, affected route, or consumer instruction, the story changes; if it only changes the volume of the argument, it does not.
