<br />Ramsey County | Multi-Jurisdiction Hazard Mitigation Plan 68 <br />Date Location Magnitude Deaths/ <br />Injuries <br />Property <br />Damage <br />Description <br />August <br />27, 2022 <br />St. Paul EF-0 0/0 $150k Several homes had damage <br />(mainly roof damage) which <br />occurred as multiple large trees <br />were either uprooted or blown <br />down along the tornado's path. <br />The maximum width was 100 <br />yards with a peak wind of 75 <br />mph. <br />Sources: National Climate Data Center; 2019 Ramsey MHMP <br />3.11.5 PROBABILITY <br />Windstorms are an annual occurrence and are likely to occur each year. Seven significant tornadoes <br />have occurred since 1970, giving a probability of approximately a 13% chance of a significant tornado <br />occurring within any given year. <br />3.11.6 CLIMATE CHANGE IMPACTS <br />While the exact relationship between climate change and tornadoes is complex and still under active <br />research, the evidence suggests that climate change is likely to impact the frequency, intensity, and <br />distribution of severe windstorms and tornadoes in the Midwest. <br />3.11.7 VULNERABILITY ASSESSMENT <br />3.11.7.1 People <br />All individuals who live, work, and recreate within Ramsey County are at risk of impact from windstorms <br />and tornadoes. The most likely impacts are from electrical outages (which affects heating/cooling, food <br />storage, communications, and use of durable medical equipment), although individuals may also suffer <br />transportation disruptions from downed trees, medical conditions from debris cleanup, auto accidents, <br />and injuries or fatalities from downed trees or blown objects. Taking cover during inclement weather <br />reduces many of these impacts. <br />3.11.7.2 Property <br />In "strong wind" conditions, small branches break off trees, and loose objects are blown about. Isolated <br />occurrences of wind damage to porches, carports, awnings, or pool enclosures may take place. Power <br />outages are common, especially in winter months. <br />In "damaging wind" conditions, wind damage occurs to unanchored mobile homes, porches, carports, <br />awnings, and pool enclosures, with some shingles blown from roofs. Large branches break off trees, <br />with weak or diseased trees blown down. Loose objects are easily blown about and can become <br />dangerous projectiles. Power outages are likely to be more extensive. Other utility outages, such as <br />communication, may also occur. Damaging high winds are considered extremely dangerous for high- <br />profile vehicles. <br />In “very damaging” and “violent wind” conditions, including tornadic winds, a wide range of impacts on <br />property may occur, depending on intensity, duration, and the vulnerability of the structures in their
