Is it getting more frequent?

Records per decade for Shenandoah 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).

Fog, smoke and funnel clouds in the 2010s: 55 records against 9 in the decade before, 55 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 Shenandoah County days with a record above.
