Heat Advisory Issued for San Juan, Puerto Rico, and U.S. Virgin Islands
The National Weather Service in San Juan, Puerto Rico, has issued a Heat Advisory effective from 10 AM to 5 PM AST on September 8, 2026, for portions of Puerto Rico and the U.S. Virgin Islands. The advisory covers 15 zones, including San Juan and Vicinity, Northeast, Southeast, Eastern Interior, North Central, Central Interior, Ponce and Vicinity, Northwest, Western Interior, Mayaguez and Vicinity, Southwest, Culebra, Vieques, St. Thomas... St. John... and Adjacent Islands, and St Croix. The advisory expires at 5 PM AST this afternoon.
The advisory warns that this level of heat affects most individuals sensitive to heat, especially those without effective cooling and/or adequate hydration. High temperatures or elevated heat indices can worsen symptoms in people with chronic conditions and increase the risk of heat-related illness, particularly across coastal areas, lowlands, interior valleys, and urban zones.
Residents are advised to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check on relatives and neighbors. The National Weather Service urges monitoring 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.
