The deadliest and costliest records

A damage figure marked "step" is a record from before 1993: NOAA then filed damage by category, and the figure is the category as entered, in the dollars of that year, not an estimate of the loss.

Is it getting more frequent?

Records per decade for Sebastian County's most frequent hazards. Counts rose everywhere after 1996, when NOAA began recording every event type, so compare decades within a hazard's complete period only (the shaded cells come before it).

Heat in the 2010s: 27 records against 7 in the decade before, 27 of them forecast-zone records. Drought in the 2010s: 25 records against 7 in the decade before, 25 of them forecast-zone records. Cells marked z rose mostly through zone records. The local National Weather Service office files these once per forecast zone, so a change in how it draws its zones or splits a storm into records moves this count as much as the weather does; read it beside the Sebastian County days with a record above.
