Drought — Allamakee, Iowa

2023-10-01 to 2023-10-31 · Allamakee, Iowa

Event narrative

Long-standing drier than normal conditions, comprised of 15 weeks of at least severe drought (D2), slightly eased in severity for Allamakee County through October. Several storms provided near normal monthly rainfall totals, easing initial extreme drought (D3) to severe drought (D2) for most of the county. Continuation of the severe drought (D2) was a result of the ongoing rainfall deficit near 6 inches from initial severe drought (D2) issuance on June 20th to the start of October.

Wider weather episode

Despite multiple rainfall events through October, there was not much change to overall drought severity. Monthly rainfall totals of 1 to 4 inches ranged from slightly below normal in Mitchell, Howard, Floyd, and Chickasaw counties to slightly above normal in Winneshiek, Fayette, Clayton, and Allamakee counties. The drought improved slightly in far northeast Iowa from extreme (D3) to severe (D2) by the end of October. Elsewhere, while ongoing below normal soil moisture became 10 to 20 percent above normal through the middle of the month, the long-standing drier than normal conditions resulted in extreme drought (D3) persisting. From the start of June through September, near 10 inches of total rainfall was 6 to 10 inches below normal.
