The , carried at the "" alert level, covered Tucson, Tanque Verde and Seven Falls. The situation was developing at the time of publication.
The Weather Service said Doppler radar indicated thunderstorms producing heavy rain across the extreme northeast portions of the Tucson area, with radar estimates of between 0.75 and 1.30 inches of rain fallen into the Agua Caliente and Tanque Verde Creek watersheds. Life-threatening flash flooding was described as ongoing or expected to begin shortly, especially along drainages feeding Agua Caliente Creek and Tanque Verde Creek.
The agency said flash flooding of creeks and streams, urban areas, highways, streets and underpasses was possible. Flash-flood prone locations listed in the included Agua Caliente Wash from Soldier Trail to Fort Lowell, Wentworth Road at Tanque Verde Wash, Tanque Verde Loop Road at Tanque Verde Wash, and Limberlost Road from Soldier Trail to Homestead Avenue.
The Weather Service advised residents to seek or stay on high ground, plan for sheltering in place and for evacuation, and to evacuate if advised. It cautioned against walking or driving in floodwaters, noting that the depth and velocity of water are not always obvious, that the ground or road may suddenly wash away and that hidden dangers may exist, and that people should not attempt to evacuate through floodwaters. It also urged people to protect property from floodwaters and purchase flood insurance, to know how to avoid injury from debris, contaminated water, carbon monoxide poisoning, electrocution and damaged buildings and infrastructure, and to seek professional review or inspection of structures and utilities before entering flooded buildings.
No information on damage or casualties was included in the available reporting.
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.
