|---|---|---|---|---|---|---|
Southern/ 2024 | Drought | January 1, 2024 | December 31, 2024 | Drought conditions impacted many Southern, Eastern and Northwestern states. This drought was more transient in its impacts over numerous states throughout the year. The states of Texas, Oklahoma and Kansas had some of the highest losses to crops from the effects of drought and heat. As the drought changed in intensity and duration throughout the year across several regions of the country. Several Northwestern states also had costly impacted to agriculture including Montana, Idaho and Washington. Numerous southern and eastern states from Mississippi through Pennsylvania also experienced crop impacts that were most severe in the Summer months. The drought conditions also strengthen through the Fall and Winter months impacting Maryland, Delaware and New Jersey. It was also one of the hottest years on record for a number of these states, which claimed more than 100 lives from excessive heat exposure. | $5.4 CI | 136 |
Northwest Winter Storm January 2024 | Winter Storm | January 12, 2024 | January 14, 2024 | A strong artic front moved across Western Washington and Oregon on January 12 and 13 dropping temperatures below freezing. This allowed freezing rain to impact areas along the coast and the Willamette Valley northward into southwest Washington. Numerous locations including Springfield and the Portland metro area were affected by the icing and strong winds, which caused significant tree damage and power outages. Numerous homes, businesses, vehicles and other infrastructure were damaged. | $1.7 CI | 20 |
Southern/ Spring-Fall 2023 | Drought | April 1, 2023 | September 30, 2023 | Drought conditions impacted numerous Southern and Midwestern states (TX, LA, OK, KS, IL, MO, NE) and surrounding states. The agriculture sector has been impacted across these affected states including damage to field crops from lack of rainfall. Ranchers have also been forced to sell-off livestock early in some regions due to high feeding costs. For the second straight year, portions of the Mississippi River have experienced low water levels impacting river commerce. This low flow has also allowed salt water from the Gulf of Mexico to migrate northward, along the bottom of the Mississippi River, impacting water quality in southern Louisiana. Several Northwestern states including Washington, Oregon and Montana have also been impacted by increasing drought effects. | $14.8 CI | 247 |
Western/ 2022 | Drought | January 1, 2022 | December 31, 2022 | Severe drought conditions impacted many Western and Central states. Large reservoirs across the West including Lake Mead, Lake Powell, Lake Oroville, and Shasta Lake, among others continue to be depleted. Lake Mead, the Nation's largest reservoir, is nearing dead pool status and is at the lowest level since it was filled in the 1930s. The Great Salt Lake is also near record-low levels. The impacts of the drought affected crop production across may states and sharply increased feeding costs for livestock. Many segments of the Mississippi River also experienced low water levels causing delays and reductions in river commerce. Extreme heat also developed for many days across Western and Central states. These excess heat conditions caused more than one hundred heat-related fatalities focused across Arizona, Nevada, California, Oregon and Texas. The 2022 drought was one of the costlier droughts on record, with a diverse array of direct impacts across different regions and industries. | $23.5 CI | 136 |
Central and Eastern Winter Storm and Cold Wave December 2022 | Winter Storm | December 21, 2022 | December 26, 2022 | Historic winter storm and powerful arctic front caused significant impact across much of the nation, bringing heavy rains, snow, ice and high winds that sent temperatures plummeting. More than 200 million people were under a winter weather advisory or warning and more than a million customers, from Texas to Maine, were left without power. Buffalo, New York was paralyzed by near hurricane force winds and continuous snow squalls, which contributed to dozens of fatalities in the region. Additional impacts were widespread frozen water pipes that led to extensive water damage in many homes, businesses and to other critical infrastructure. | $9.0 CI | 87 |
Western Wildfires Spring-Fall 2022 | Wildfire | April 1, 2022 | November 30, 2022 | Severe drought conditions and periods of extreme heat provided conditions favorable for another damaging western wildfire season most focused across New Mexico, Oregon, Idaho, Montana, California and Alaska. The Calf Canyon and Hermits Peak Fires in New Mexico merged in April consuming over 340,000 acres. This became the largest and most destructive wildfire on record in New Mexico - damaging or destroying over 1,000 structures. Other large wildfires included the Double Creek Fire (Oregon), the Moose Fire (Idaho), the Mosquito Fire (California), the Trail Creek Fire (Montana) and the Lime Complex Fire (Alaska), among many others. Over 7.5 million acres burned nationally during the 2022 wildfire season. | $3.3 CI | 17 |
Western Wildfires 2021 | Wildfire | June 1, 2021 | December 31, 2021 | Severe drought conditions and periods of extreme heat provided conditions favorable for another damaging western wildfire season most focused across California, Colorado, Oregon, Washington, Idaho, Montana and Arizona. The Dixie Fire consumed over 960,000 acres making it the second-largest wildfire on record in California while also destroying more than 1,000 structures. California's Caldor Fire grew rapidly during August, threatening South Lake Tahoe communities and burned over 220,000 acres. Other large wildfires included the Ford Corkscrew Fire (Washington), the Bootleg Fire (Oregon), the Boundary Fire (Idaho), the Trail Creek Fire (Montana) and the Telegraph Fire (Arizona), among many others. There was also the Marshall Fire in Boulder County, Colorado on December 30 that damaged or destroyed more than 1,000 homes and businesses. This wildfire is the most destructive on record in Colorado. Throughout the wildfire season air quality was also a concern across numerous states, as ash and fine particulates from wildfires obscured the skies and made outdoor activities more hazardous. Over 7.1 million acres burned nationally during the 2021 wildfire season. | $12.1 CI | 8 |
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. | $10.2 CI | 229 |
Northwest, Central, Eastern Winter Storm and Cold Wave February 2021 | Winter Storm | February 10, 2021 | February 19, 2021 | Historic cold wave and winter storm impacts many northwest, central and eastern states. Temperature departures exceeding 40.0 degrees F (22.2 degrees C) below normal occurred from Nebraska southward to Texas. The prolonged arctic air caused widespread power outages in Texas, as well as other southern states, with multiple days of sustained below-freezing temperatures. At the peak of the outage, nearly 10 million people were without power. Additional impacts were frozen water pipes, which burst upon thawing causing water damage to buildings. These extreme conditions also caused or contributed to the direct and indirect deaths of more than 210 people in Texas alone. This count does not include excess mortality that may be hundreds of additional deaths. There were also snow and ice impacts across numerous states including Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Tennessee, Louisiana, Mississippi, Colorado, Oregon and Washington. This is now the costliest U.S. winter storm event on record, more than doubling the inflation-adjusted cost of the 'Storm of the Century' that occurred in March 1993. | $27.2 CI | 262 |
Western Wildfires - California, Oregon, Washington Firestorms Fall 2020 | Wildfire | August 1, 2020 | December 30, 2020 | A record-breaking U.S. wildfire season burned more than 10.2 million acres. California more than doubled its previous annual record for area burned (last set in 2018) with over 4.1 million acres. Five of the top six largest wildfires on record in California (dating to 1932) burned during August and September. The August Complex was the largest California wildfire, which began as 37 separate wildfires within the Mendocino National Forest, set off after storms caused >10,000 lightning strikes across Northern California. Approximately 10,500 structures were damaged or destroyed across California. Oregon also had historic levels of wildfire damage, as over 2,000 structures burned. These wildfires spread rapidly and destroyed several small towns in California, Oregon and Washington. Colorado also had a severe wildfire season, as its three largest wildfires on record burned during 2020. Dense wildfire smoke also produced hazardous air quality that affected millions of people that also included major cities for weeks. Hundreds of additional wildfires also burned across other Western states. | $19.9 CI | 46 |
Western/ Summer-Fall 2020 | Drought | June 1, 2020 | December 30, 2020 | Widespread, continuous drought and record heat affected more than a dozen Western and Central states for much of the summer, fall and into the winter months. 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 |
Western Wildfires, California Firestorm Summer-Fall 2018 | Wildfire | June 1, 2018 | December 31, 2018 | In 2018, California has experienced its costliest, deadliest and largest wildfires to date, with records back to 1933. The Camp Fire is the costliest and deadliest wildfire - destroying more than 18,500 buildings. California also endured its largest wildfire on record - the Medincino Complex Fire - burning over 450,000 acres. Additionally, California was impacted by other destructive wildfires: the Carr Fire in Northern California and the Woolsey Fire in Southern California. The total 2018 wildfire costs in California (with minor costs in other Western states) approach $24.0 ($30.0) billion - a new U.S. record. In total, over 8.7 million acres has burned across the U.S. during 2018, which is well above the 10-year average (2009-2018) of 6.8 million acres. The last 2 years of U.S. wildfire damage has been unprecedented in damage, with losses exceeding $40.0 ($50.0) billion. | $30.0 CI | 106 |
Western Wildfires, California Firestorm Summer-Fall 2017 | Wildfire | June 1, 2017 | December 31, 2017 | A historic firestorm damages or destroys over 15,000 homes, businesses and other structures across California in October. The combined destruction of the Tubbs, Atlas, Nuns and Redwood Valley wildfires represent the most costly wildfire event on record, also causing 44 deaths. Extreme wildfire conditions in early December also burned hundreds of homes in Los Angeles. Numerous other wildfires across many western and northwestern states burn over 9.8 million acres exceeding the 10-year annual average of 6.5 million acres. Montana in particular was affected by wildfires that burned in excess of 1 million acres. These wildfire conditions were enhanced by the preceding drought conditions in several states. | $23.2 CI | 54 |
Western/ Summer-Fall 2016 | Wildfire | June 1, 2016 | December 31, 2016 | Western and Southern states experienced an active wildfire season with over 5.0 million acres burned nationally. Most notable was the firestorm that impacted Gatlinburg, Tennessee with hurricane-force wind gusts in extremely dry conditions creating volatile wildfire behavior. These wildfires destroyed nearly 2,500 structures and caused 14 fatalities. The drought conditions in many areas of the Southeast and California worsened the wildfire potential. | $3.1 CI | 21 |
Western Drought 2015 | Drought | January 1, 2015 | December 31, 2015 | Drought conditions were present across numerous western states (CA, NV, OR, WA, ID, MT, UT, AZ) with the most severe conditions continuing to plague California for all of 2015. The agriculture sector was again impacted by a lack of rainfall resulting in hundreds of thousands of acres of farmland remaining fallow and requiring excess groundwater pumping to irrigate existing agriculture interests. Wildfire conditions were further enhanced by the ongoing drought. California experienced extensive damage from both drought and wildfire impacts. Drought conditions did improve dramatically across Texas and Oklahoma, in the form of several major flood events. | $6.0 CI | 0 |
Western and Alaskan Wildfires Summer-Fall 2015 | Wildfire | June 1, 2015 | November 30, 2015 | Wildfires burned over 10.1 million acres across the U.S. in 2015, surpassing 2006 for the highest annual total of U.S. acreage burned since record-keeping began in 1960. The most costly wildfires occurred in California where over 2,500 structures were destroyed due to the Valley and Butte wildfires with the insured losses alone exceeding $1.0 ($1.3) billion.
