The August 11, 1997 record is thin on the weather side: NCEI holds 5 reports, in Denver, Jefferson and Pueblo counties, at Pueblo, South Denver and Lakewood, with hail up to 2 inches. The insurance side is larger: $128 million in insured losses in 1997 dollars.
The exact date and that figure come from a 2009 Claims Journal article citing RMIIA. RMIIA's own table lists the event as August 1997, at $249 million in 2025 dollars.
