Winter storm

Central and Eastern Winter Storm and Cold Wave

Cost:$9.5B
Deaths:87
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.
Tropical cyclone

Hurricane Ida

Cost:$89.8B
Deaths:96
Category 4 Hurricane Ida made landfall near Port Fourchon, Louisiana with maximum sustained winds of 150 mph (240km/h) and a minimum central pressure of 930 mb. Ida was one of three hurricanes in recorded history to make landfall in Louisiana with 150 mph winds, along with Hurricane Laura in 2020 and the 'Last Island' hurricane of 1856. Grand Isle, Louisiana took a direct hit with 100% of its homes damaged and nearly 40% were nearly-to-completely destroyed. There was heavy damage to the energy infrastructure across southern Louisiana causing widespread, long duration power outages to millions of people. Parts of New Orleans were without power for nearly a week due to the widespread damage. As the remnants of Ida moved into the Northeast it merged with a frontal system creating severe weather and flash flooding across a wide region from eastern Pennsylvania to New York. Flash flood emergencies were declared in New Jersey and New York for the first time, producing damage to homes, businesses, vehicles and infrastructure while also causing dozens of fatalities.
Tropical cyclone

Tropical Storm Fred

Cost:$1.6B
Deaths:7
Tropical Storm Fred made landfall near Panama City, Florida. As Fred progressed northward it caused torrential flooding across the southern Appalachian Mountains with more than a foot of rainfall reported in some locations of western North Carolina. This flash flooding caused damage to many homes, businesses, vehicles, roads and bridges, in additional to several fatalities. Fred also produced nearly a dozen tornadoes across the Northeast as it moved up the East Coast.
Tropical cyclone

Tropical Storm Elsa

Cost:$1.5B
Deaths:1
Tropical Storm Elsa made landfall in Taylor County, Florida producing heavy rain, wind, flooding and tornadoes in portions of Florida, Georgia and the Carolinas, as well as flooding across parts of the Northeast.

Tropical cyclone

Hurricane Isaias

Cost:$6.1B
Deaths:16
Hurricane Isaias made landfall in southeastern North Carolina as a category 1 storm. Isaias accelerated up the East Coast, resulting in widespread damage and power outages across New York, New Jersey and Pennsylvania. There was also considerable inland flooding most notably in Pennsylvania. In addition, 34 tornadoes developed across North Carolina, Virginia, Maryland, Delaware and New Jersey due to Isaias. Many tornadoes were weaker (EF-0 and EF-1) producing scattered damage to agriculture, structures and residences. Isaias also produced several EF-2 tornadoes and one EF-3 tornado that caused damage in coastal North Carolina and Virginia.
Severe storm

Southeast and Eastern Tornado Outbreak

Cost:$4.5B
Deaths:35
Outbreak of at least 140 tornadoes from Texas to Maryland including 3 EF4s, 12 EF3s, 20 EF2s, 77 EF1s and 28 EF0s. Damage was extensive and highly destructive to many homes, vehicles and businesses across more than a dozen Southeast and Eastern states.

Drought

West/Northeast/Southeast Drought

Cost:$4.9B
California's 5-year drought persisted during 2016 while new areas of extreme drought developed in states across the Northeast and Southeast. The long-term impacts of the drought in California have damaged forests where 100+ million trees have perished and are a public safety hazard. The agricultural impacts were reduced in California as water prices and crop fallowing declined. However, agricultural impacts developed in Northeast and Southeast due to stressed water supplies.
Severe storm

Southeast and Eastern Tornadoes

Cost:$1.5B
Deaths:10
Early outbreak of tornadoes and severe weather across many southern and eastern states including (AL, CT, FL, GA, LA, MA, MD, MS, NC, NJ, NY, PA, SC, TX, VA). There were at least 50 confirmed tornadoes causing widespread damage.
Winter storm

A large winter storm and associated cold wave impacted many central, eastern and northeastern states (CT, DE, GA, IL, KY, MA, MD, ME, MI, NC, NH, NJ, NY, OH, PA, RI, SC, TN, VA). The city of Boston was particularly impacted as feet of snow continued to accumulate causing load-stress on buildings and clogging transportation corridors. Total, direct losses in Massachusetts alone exceed $1.0 billion for this event, with considerable damage in many other states.
Tropical cyclone

Hurricane Sandy

About State-Level Data

State-level summaries and charts on this page are derived from authoritative data that assigns costs to each affected state for every billion-dollar disaster. Those state-specific costs are shown only as binned ranges. The event cards and table list each disaster's full event cost rather than an exact state allocation.

Climate Central maintains this comprehensive database tracking U.S. weather and climate disasters since 1980 where overall damages/costs reached or exceeded $1 billion (including Consumer Price Index adjustment). As the steward of this dataset, Climate Central is committed to maintaining the scientific rigor and methodological standards established by NOAA's National Centers for Environmental Information (NCEI) while enhancing the dataset's utility for climate communication and public understanding of climate risks.
