How we got these numbers: These are unique alerts published by South Dakota's department of transportation (DOT) feed, from a daily copy taken Sept. 1 through Sept. 30, 2026. Each alert is counted once. An alert posted and removed between two daily copies is not counted. States publish different things, so compare a state with its own earlier months, not with other states. Fire figures are as of Sept. 30, 4 PM Pacific.
