Ramsey County Multi-Hazard Mitigation Plan, 2018 <br /> <br />Page | 56 <br /> <br />In July of 2009, hail was reported from Maplewood southeast across North St. Paul. Minor damage was <br />noted near the intersection of Century Avenue and Holloway Avenue. <br />A hailstorm caused severe damage at the University of Minnesota St. Paul campus in May of 2001. The <br />damage estimate for the county as a whole was $2 million. <br />Hail is a concern in Ramsey County due to the damage it can inflict on property. Table 18 shows storms <br />producing hail greater than 1 inch in diameter in Ramsey County. <br />Table 18.

Since the impact of more frequent or intense storms <br />can be larger than the impact of average temperature, climate scientists are actively researching the <br />connections between climate change and severe storms (National Climate Assessment Development <br />Advisory Committee, 2013). <br />The occurrence of very heavy precipitation has increased in Minnesota in recent decades and future <br />projections also indicate this will continue (International Climate Adaptation Team, 2013). While it is <br />unknown if this precipitation will occur during severe storms that produce hail, the possibility has not <br />been ruled out.
