NCEI has 255 storm events on record for Minnesota in 1984.

FEMA has no disaster declaration for the state with a date in 1984.

OpenFEMA has 141 NFIP claims with a 1984 year of loss. The NFIP paid $1,297,876 on these claims.

NCEI recorded tornado events from 1950, and hail and thunderstorm wind events from 1955. It recorded all event types from 1996.

The NWS collects event reports from a variety of sources, which include (but are not limited to): county, state, and federal emergency management officials, local law enforcement officials, SKYWARN spotters, NWS damage surveys, newspaper clipping services, the insurance industry, and the general public, among others.

The National Weather Service reports property and crop damage estimates using available data at the time of event reporting. These values should therefore be considered broad estimates. Damage amounts are not adjusted for inflation.
