Western Drought and Heat Wave 2021 | Drought | January 1, 2021 | December 31, 2021 | Western drought conditions were persistent throughout 2021, as the drought expanded and intensified across many Western states. A historic heat wave also developed for many days across the Pacific Northwest shattering numerous all-time high temperature records across the region. This prolonged heat dome was maximized over the states of Oregon and Washington and extended well into Canada. These extreme temperatures impacted several major cities and millions of people. For example, Portland reached a high of 116 degrees F while Seattle reached 108 degrees F. These extreme temperatures caused hundreds of direct and indirect heat-related fatalities across Oregon and Washington, not including excess mortality that may be hundreds of additional deaths. This combined drought and heat rapidly dried out vegetation across the West, impacting agriculture. Low water levels also forced the hydroelectric power plant at Lake Oroville in California to shut down for the first time since it opened in 1967. | $10.1 CI | 229 |

Persistent above-average temperatures and precipitation deficits caused D3 (extreme) and D4 (exceptional) drought coverage in December that was the largest extent since August 2012. Death Valley recorded a temperature of 130 degrees F - the highest measured temperature globally in decades - while Los Angeles county recorded a record high of 121 degrees F. There were considerable crop and livestock impacts across the West and Central states from both the persistent heat and increasingly dry conditions. The combined drought and heat also assisted in drying out vegetation across the West that contributed to the Western wildfire potential and severity. | $5.4 CI | 45 |
Central Severe Weather - Derecho August 2020 | Severe Storm | August 10, 2020 | August 10, 2020 | A powerful derecho traveled from southeast South Dakota to Ohio, a path of 770 miles in 14 hours producing widespread winds greater than 100 mph.
