<br />Ramsey County | Multi-Jurisdiction Hazard Mitigation Plan 76 <br />Date Type Deaths/ <br />Injuries <br />Property <br />Damage <br />Description <br />July 24, 2009 Hail 0/0 $15k A strong cold front moved through the region <br />Friday morning and generated a line of strong <br />to severe thunderstorms that affected areas <br />from far east central Minnesota, into west <br />central Wisconsin. Several reports of golf ball <br />size hail were observed in the east metro of <br />the Twin Cities. <br />September <br />21, 2010 <br />Hail 0/0 $5M Several reports of large hail, up to the size of <br />half dollars, occurred from the Highland Park <br />area of Saint Paul, northeast across the north <br />side of the city. <br />August 25, <br />2013 <br />Excessive <br />Heat <br />0/216 None <br />reported <br />Heat indices of 105° F occurred during the <br />Minnesota State Fair. 216 people were <br />treated at State Fair medical aid stations for <br />heat-related illnesses. Of those 216, 10 were <br />transported to area hospitals. Minneapolis <br />schools also canceled outdoor athletic <br />practices during this period of extreme heat. <br />July 2015 Extreme <br />Heat <br />0/0 None <br />reported <br />Several observations across Ramsey County <br />measured heat indices over 105° F for two <br />days in a row. The highest heat index value <br />was 116° F. <br />8 Significant <br />Incidents <br />- 1/216 $7,015,000 <br />total claimed <br />-- <br />Sources: NCDC; 2019 Ramsey MHMP <br />3.11.5 PROBABILITY <br />Summer weather hazards are an annual occurrence and are likely to occur each year. Eight significant <br />summer weather incidents have occurred since 1970, giving a probability of approximately a 14.5% <br />chance of a significant summer weather incident occurring within any given year. <br />3.11.6 CLIMATE CHANGE IMPACTS <br />Climate change is expected to have dramatic impacts on weather patterns in Minnesota. These include <br />more extreme weather patterns, including increased periods of extreme heat, enhanced lightning <br />activity, changes in hail patterns and more intense storms. Climate change could have the following <br />impacts: <br />• Increased Extreme Heat: This includes more frequent and severe heatwaves, higher average <br />summer temperatures, and longer duration of hot spells. Minnesota is getting warmer, <br />especially winter nights in the northern parts of the state. Daily average minimum temperatures <br />during winter (Dec-Feb) have increased 4.9 degrees in southern Minnesota. <br />• Enhanced Lightning Activity: Increased atmospheric instability may lead to more <br />thunderstorms, with higher temperatures and humidity levels contributing to more frequent <br />lightning strikes.
