To determine potential financial loss estimates to tornadoes in the planning area, the available
historical loss data was annualized to determine future potential losses. The planning team
obtained loss data for the National Climatic Data Center (NCDC) storm events (1993 – 2012).
Table 3.156 shows the estimates financial loss for each county in Region L.

Tornadoes have a warning time of approximately 30 minutes or less. They can change paths
quickly, which limits the time in which to take shelter. Tornadoes are very difficult to see at
night, and during intense rain and hail, often give very little or no warning of when a tornado is
on the ground.
To refine and access the relative vulnerability of each of Region L’s counties to tornadoes,
assigned ratings to pertinent factors were examined at the county level. These factors are:
social vulnerability index, prior events, prior annualized property damage, building exposure
valuation, population density, crop exposure and annualized crop loss. Then a rating value of 1-
10 was assigned to the data obtained for each factor and then weighted equally and factored
together to obtain overall vulnerability scores for comparison and to determine the most
vulnerable counties.
Tornados that touch-down can create a unique path of destruction unlike a wide-spread winter
storm event that can affect entire regions of the State. So using the prior events as a factor can
give the perception that a county has a higher overall vulnerability to tornadoes.
The following are the data sources for the rating factors: Social Vulnerability Index for Kansas
