Deaths
Southwest/Southern Plains Drought
Summer-Fall 2018
DroughtJune 1, 2018December 30, 2018Drought conditions were present across numerous Southwestern and Plains states (TX, OK, KS, MO, CO, NM, AZ, UT). The most extreme drought conditions continue to persist across the Four Corners region of the Southwest. The agriculture sector has been impacted across the affected states including damage to field crops from lack of rainfall. Ranchers have also be forced to sell-off livestock early in some regions due to high feeding costs.$3.8 CI0
Colorado Hail Storm
June 2018
Severe StormJune 18, 2018June 19, 2018Severe hail storms cause golf ball to baseball-sized hail and widespread damage in many areas from northern Denver to Boulder and Fort Collins. Many homes, businesses and vehicles were impacted. Utah also experienced moderate hail damage.$2.8 CI0
U.S. Drought/Heat Wave
2012
DroughtJanuary 1, 2012December 31, 2012The 2012 drought is the most extensive drought to affect the U.S. since the 1930s. Moderate to extreme drought conditions affected more than half the country for a majority of 2012. The following states were affected: CA, NV, ID, MT, WY, UT, CO, AZ, NM, TX, ND, SD, NE, KS, OK, AR, MO, IA, MN, IL, IN, GA. Costly drought impacts occurred across the central agriculture states resulting in widespread harvest failure for corn, sorghum and soybean crops, among others. The associated summer heat wave also caused 123 direct deaths, but an estimate of the excess mortality due to heat stress is still unknown.$41.7 CI123
Western/Eastern Drought/Heat Wave
Summer-Fall 2007
DroughtJune 1, 2007November 30, 2007Severe drought with periods of extreme heat over most of the southeast and portions of the Great Plains, Ohio Valley, and Great Lakes area, resulting in major reductions in crop yields, along with very low stream-flows and lake levels. Includes states of ND, SD, NE, KS, OK, TX, MN, WI, IA, MO, AR, LA, MS, AL, GA, NC, SC, FL, TN, VA, WV, KY, IN, IL, OH, MI, PA, NY.$5.5 CI15
Western Fire Season
Fall 2002
WildfireSeptember 1, 2002November 30, 2002Major wildfires over 11 western states from the Rockies to the west coast due to drought and periodic high winds, with over 7.1 million acres burned.$2.3 CI21
U.S. Drought
Spring-Fall 2002
DroughtMarch 1, 2002November 30, 2002Moderate to extreme drought over large portions of more than 30 states, including the western states, the Great Plains, and much of the eastern U.S.$16.0 CI0
Northern Plains Drought
Summer-Fall 1989
DroughtJune 1, 1989November 30, 1989Severe summer drought over much of the northern plains with significant losses to agriculture. The states impacted include CO, IA, IL, KS, MO, ND, NE, NV, SD, TX and UT.$7.8 CI0

Deaths associated with drought are the result of heat waves. (Not all droughts are accompanied by extreme heat waves.)

Flooding events (river basin or urban flooding from excessive rainfall) are separate from inland flood damage caused by tropical cyclone events.
