Extreme Weather Event Map: Click on any circle to learn about one of the billion-dollar weather events, or any state to learn about billion-dollar droughts. All events occurred between 2000 and 2013.
This map shows billion-dollar weather events in the United States since 2000, as identified by the National Oceanic and Atmospheric Administration’s National Climatic Data Center. The Top 10 costliest events are listed at the bottom of this page, along with a description of major U.S. droughts since 2000.
Floods, Tornadoes, Thunderstorms, Hail, Tropical Storms, Wildfires, and Winter Storms are all shown as circles, with the costs indicated by the area of the circles (see image to the right). The location of the circles correspond to places where impacts were experienced (note: locations are approximate; many of the events actually impacted a large area, beyond
the boundaries of the circle). Droughts are not shown by circles, but by the shading in the states – states with darker colors have experienced more droughts since 2000, while states that are lightly shaded have experienced fewer droughts. No billion dollar events have occurred in Hawaii since 2000; some of the wildfire impacts (e.g., fire seasons in 2006, 2007, and 2008) included damages in Alaska, but the markers appear in the continental United States.
Many of these events, including heat waves and heavy rainfall, are likely to become more frequent and intense as a result of climate change. Climate change can also worsen the impacts of some of these events. For example, sea level rise can increase the impacts of coastal storms and warming can place more stress on water supplies during droughts. But it’s important to note that not ALL of these events will necessarily happen more frequently as a consequence of climate change. The links between climate change and tornadoes, ice storms, and hail are unclear, and represent current areas of research.
These events demonstrate ways our communities and infrastructure are vulnerable to extreme weather, and that the costs associated with impacts can be large.

Weathering the Storm - Extreme weather is costly. The events shown on the map above all cost billions of dollars, and several events had widespread and long-lasting implications.
C2ES has investigated how companies are perceiving the risks associated with extreme weather and climate change. Focusing on Standard and Poor’s (S&P) Global 100 companies, we found that 90 percent of these companies identify extreme weather and climate change as risks, and most have experienced climate impacts or expect to within 10 years. Although some companies have taken action, only a few have used climate-specific tools to comprehensively assess risks and develop resilience plans. Check out the report to learn more, and to learn about the steps business and government can take to close the resilience gap.

|Event and Date||Cost||Fatalities||Description|
|$148 billion||1,833||The hurricane initially hit as a Category 1 near Miami, FL, then as a stronger Category 3 along the eastern LA-western MS coastlines, resulting in severe storm surge damage (maximum surge probably exceeded 30 feet) along the LA-MS-AL coasts, wind damage, and the failure of parts of the levee system in New Orleans. High winds and some flooding occurred in Ala., Fla., Ga., Ind., Ky., Miss., Ohio and Tenn.|
|$65.7 billion||159||Sandy caused extensive damage across several northeastern states (Conn., Del., Mass., Md., N.J., N.Y., R.I.) due to high wind and coastal storm surge, particularly in N.J. and N.Y. Damage from wind, rain and heavy snow also extended more broadly to other states (N.C., N.H., Ohio, Pa., Va., W.Va.), as Sandy merged with a developing Nor'easter. Sandy interrupted critical water and electrical services in major population centers and caused 159 deaths (72 direct, 87 indirect). Sandy also shut down the New York Stock Exchange for two consecutive business days, which last happened in 1888 due to a major winter storm.|
|$30.0-$30.3 billion||123||The 2012 drought was the most extensive in the U.S. since the 1930s. Moderate to extreme drought conditions affected more than half the country for a majority of 2012. Costly impacts included widespread harvest failure for corn, sorghum and soybean crops, among others. The associated summer heat wave also caused 123 direct deaths, but the excess mortality due to heat stress is still unknown.|
|$29.2 billion||112||Ike made landfall in Texas as a Category 2 hurricane. It was the largest Atlantic hurricane on record by size, causing a considerable storm surge in coastal TX and significant wind and flooding damage in Ark., Ill., Ind., Ky., La., Mich., Mo., Ohio, Pa., Tenn. and Texas. Severe gasoline shortages occurred in the Southeast due to damaged oil platforms, storage tanks, pipelines and refineries.|
|$19 billion||35||The Category 3 hurricane hit SW Florida, resulting in strong damaging winds and major flooding across southeastern Florida. Prior to landfall, Wilma as a Category 5 recorded the lowest pressure (882 mb) ever recorded in the Atlantic basin.|
|$19 billion||119||The Category 3 hurricane hit Texas-Louisiana border coastal region, creating significant storm surge and wind damage along the coast, and some inland flooding in the Fla. panhandle, Ala., Miss., La., Ark., and Texas. Prior to landfall, Rita reached the third lowest pressure (897 mb) ever recorded in the Atlantic basin.|
|$18.5 billion||35||The Category 4 hurricane made landfall in southwest Florida, resulting in major wind and some storm surge damage in FL, along with some damage in the states of S.C. and N.C..|
|$17.2 billion||57||The Category 3 hurricane made landfall on Gulf coast of Ala., with significant wind, storm surge, and flooding damage in coastal Ala. and Fla. panhandle, along with wind/flood damage in the states of Ga., Miss., La., S.C., N.C., Va., W.Va., Md., Tenn., Ky., Ohio, Del., N.J., Pa., and N.Y.|
|$12.0-$12.4 billion||95||In Texas and Oklahoma, a majority of range and pasture lands were classified in "very poor" condition for much of the 2011 growing season.|
|$11.1 billion||48||The Category 2 hurricane made landfall in east-central Fla., causing significant wind, storm surge, and flooding damage in FL, along with considerable flood damage in the states of Ga., N.C., N.Y. and S.C. due to 5-15 inches of rain.|

|2013||N/A||53||The 2013 drought slowly dissipated from the historic levels of the 2012 drought, as conditions improved across many Midwestern and Plains states. However, moderate to extreme drought did remain or expand into western states. In comparison to 2011 and 2012 drought conditions the US experienced only moderate crop losses across the central agriculture states.||Ariz., Calif., Colo., Idaho, Kan., Neb., Nev., N.M., Okla., Ore., S.D., Texas, Utah, Wyo.|
|2012||$30.0-$30.3 billion||123||The 2012 drought was 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. Costly drought impacts occurred across the central agriculture states resulting in widespread harvest failure for corn, sorghum and soybean crops, among others.
