How we got these numbers: These are unique alerts published by Montana'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. Fire figures are as of Oct. 31, 4 PM Pacific. Border waits are from U.S. Customs and Border Protection, saved every hour. Readings over five hours were treated as feed errors.
