Frequently asked questions
What was the largest hail size on May 31, 2024 in Denver County?+
NOAA's Storm Events Database recorded a peak hail size of 2.75" during the May 31, 2024 storm in Denver County, Colorado. Hail of this size (2.75") routinely causes total roof replacement, broken windshields, and structural damage. Denver County properties exposed to this storm should have received insurance-eligible damage.
How many hail events were recorded during this storm?+
32 individual hail observations were recorded in Denver County on May 31, 2024, between approximately 10:02 PM MDT and 11:10 PM MDT. Each NOAA record represents either a ground-verified observation by a National Weather Service spotter or a radar-derived measurement.
Can I file an insurance claim for hail damage from this storm?+
Most homeowner's insurance policies in Colorado cover hail damage under the "wind and hail" peril. Standard policies require claims to be filed within 1-2 years of the date of loss, though this varies by carrier. The May 31, 2024 date is the NOAA-recorded date of loss for properties in Denver County. If your roof shows damage and your address was in the storm path, scheduling a free professional inspection is the standard first step.
How accurate is NOAA's hail size measurement?+
NOAA combines ground-verified reports (physically observed and measured hailstones reported by trained spotters, NWS offices, or law enforcement) with NEXRAD radar-derived size estimates. Ground reports are the gold standard. Radar estimates are a class rather than a measurement: MESH is tuned so that roughly 75% of measured hail comes in at or below the estimate — a bias, not a symmetric error bar. Each event in NOAA's Storm Events Database has a unique event ID that adjusters can independently verify.
Was my property in the storm path?+
The storm map above shows the location of each individual hail event in this storm. Enter your address in the HailScore lookup tool for a property-level report that checks all four NOAA publishers (Storm Events, NEXRAD radar, MRMS, CoCoRaHS) against your exact coordinates.
