Wind Advisory in Effect for Treasure Valley This Evening
The National Weather Service Boise ID has issued a Wind Advisory for the Lower and Upper Treasure Valley, including Caldwell, Nampa, and Boise, effective from 6 PM to 10 PM MDT this evening, August 21, 2026. The advisory was issued at 12:48 PM MDT.
South winds of 25 to 35 mph with gusts up to 65 mph are expected. Gusty winds will blow around unsecured objects, and tree limbs could be blown down, with a few power outages possible. The advisory warns that winds this strong can make driving difficult, especially for high-profile vehicles, and advises extra caution.
A separate Heat Advisory is in effect until 9 PM MDT this evening, with temperatures expected to reach 98 to 103 degrees. The advisory recommends drinking plenty of fluids, staying in an air-conditioned room, staying out of the sun, and checking on relatives and neighbors. It also advises taking extra precautions when outside, wearing lightweight and loose-fitting clothing, and limiting strenuous activities to early morning or evening. Anyone overcome by heat should be moved to a cool and shaded location, and heat stroke is an emergency—call 9 1 1.

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.
