HazardHub Damaging Hail Risk

The HazardHub Damaging Winds Risk File is part of the Convective Storm Suite which also includes Lightning, Damaging Winds, and Tornados.

The National Oceanic and Atmospheric Administration (NOAA) reported multiple severe (1” +) hail storms between 2013 through 2015 caused billions of dollars’ worth of damage across the US. In April, 2015 alone, powerful storms with hail brought widespread damage to Texas, Missouri, and Illinois. Additional storms caused hail damage across the Central, Southeast and Northeast U.S. Each of these storms are estimated by the NO AA to have caused over $1 billion in damage. A total of 2,116,980 hail loss claims were identified during the same period .

Damaging hail events are a product of convective storms, often called thunder storms, that occur everywhere in the United States but most frequently in the areas east of the Rockies where warm, moist air from the Gulf of Mexico meets cooler air sweeping southward.

The HazardHub Damaging Hail Risk File was compiled from long-term NOAA Doppler radar and other sources. The NOAA data contains almost 30 years of large hail event data for every county in the United States consisting of over 31 million records.
