2003 was rated as an EF2. Total damages to property were reported as $7.023 million, with 2<br />

injuries during <strong>the</strong> EF2 event.<br />

Between <strong>the</strong> years 2000 and 2012, Wyandotte County had a total of 3 tornado events. Two<br />

were rated as EF0s, and one on 4 May 2002 was rated an EF4. This tornado caused $15.5<br />

million in property damage and resulted in 2 deaths and 30 injuries.<br />

Because it was determined that Region L is in Zone IV due to potential wind speeds, and due to<br />

historic events, <strong>the</strong> planning committee determined that <strong>the</strong> planning area could experience an<br />

EF5 tornado. The magnitude of a tornado this size would be catastrophic. It could result in<br />

multiple deaths, and more than 50% of property could be severely damaged.<br />

Probability of Future Events<br />

All of Kansas is susceptible to tornadoes, and Region L is no exception. While <strong>the</strong>re have not<br />

been any tornadoes greater than an EF1 since <strong>the</strong> last plan, <strong>the</strong> probability remains “Highly<br />

Likely” that an event of any size will occur within <strong>the</strong> next three years.<br />

• Johnson County has had 9 tornado events within <strong>the</strong> last 12 years, resulting in a 75%<br />

chance of this occurring in a given year.<br />

• Leavenworth County has had 10 tornado events within <strong>the</strong> last 12 years, resulting in an<br />

83% chance of a tornado occurring in any given year.<br />

• Wyandotte County has had 3 tornadoes within <strong>the</strong> last 12 years, resulting in a 25%<br />

chance of <strong>the</strong> county having ano<strong>the</strong>r tornado within <strong>the</strong> year.<br />

Impact and Vulnerability<br />

When Figures 3.75 and 3.76 above are compared, it is apparent that Region L is in a high<br />

tornado activity area. Region L resides in Zone IV, which is <strong>the</strong> highest wind zone <strong>the</strong>re is, and<br />

is a good indicator of <strong>the</strong> potential for tornadoes.<br />

Table 3.154 shows <strong>the</strong> incidence of tornadoes and statistics in <strong>the</strong> Region from 1952 – 2011.<br />

Insured Crop Loss Data<br />

According to <strong>the</strong> USDA Risk Management Agency, insured crop losses for Region L as a result<br />

of tornado damage for <strong>the</strong> ten year period of 2002-2011 totaled $0.00 as shown in Table 3.155.<br />
