How we got these numbers: These are unique alerts published by Idaho's department of transportation (DOT) feed, from a daily copy taken Oct. 1 through Oct. 31, 2026. Each alert is counted once. An alert posted and removed between two daily copies is not counted. Not all states report the same data, so compare each place with its own earlier months. 3 alerts this feed carried for roads in Oregon and Utah were removed. Those states' own feeds carry them. Fire figures are as of Oct. 31, 4 PM Pacific.
