Summary CPI-AUnadjusted
(in Billions)
East Coast Storm and Flooding
December 2023
FloodingDecember 16, 2023December 18, 2023Powerful east coast storm from Florida to Maine produced widespread impacts from heavy rainfall, flooding, high winds and coastal erosion. The heavy rainfall and snowmelt were amplified by record-high temperatures in the Northeast.$1.3 CI5
Northeastern Flooding and North Central Severe Weather
July 2023
FloodingJuly 9, 2023July 15, 2023Severe storms brought devastation and flooding to portions of the Northeast, as areas reported up to eight inches of rain within a 24-hour period. Montpelier, Vermont received a record-breaking 5.28 inches of rain, flooding the city and damaging thousands of homes and businesses. The wide scale flooding in Vermont was similar to the flood impacts from Hurricane Irene in 2011. Early estimates put the flood damage in West Point, New York at more than $100 ($103.0) million. There was also considerable damage to roads, bridges and agriculture across the Northeast. Severe storms also caused high wind and hail impacts across Wisconsin, Minnesota and Illinois.$2.2 CI10
Northeastern Winter Storm/Cold Wave
February 2023
Winter StormFebruary 2, 2023February 5, 2023A strong winter storm produced snow, high winds and bitter cold across numerous Northeastern states. High winds caused widespread power outages in Massachusetts while Mount Washington, New Hampshire observed a wind chill temperature of -108 degrees Fahrenheit. This was one of the coldest wind chill temperatures ever recorded in the United States.$1.8 CI1
Central and Eastern Winter Storm
January 2018
Winter StormJanuary 3, 2018January 5, 2018A Nor'easter caused damage across many Northeastern states including MA, NJ, NY, CT, ME, NH, PA, MD, RI, SC, TN, VA, NC and GA.$1.3 CI22
West/Northeast/Southeast Drought
DroughtJanuary 1, 2016December 31, 2016California'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.$4.6 CI0
Central and Eastern Winter storm, Cold Wave
February 2015
Winter StormFebruary 14, 2015February 20, 2015A 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 ($1.3) billion for this event, with considerable damage in many other states.$4.0 CI30
Hurricane Sandy
October 2012
Tropical CycloneOctober 30, 2012October 31, 2012Extensive damage across several northeastern states (MD, DE, NJ, NY, CT, MA, RI) due to high wind and coastal storm surge, particularly NY and NJ. Damage from wind, rain and heavy snow also extended more broadly to other states (NC, VA, WV, OH, PA, NH), as Sandy merged with a developing Nor'easter. Sandy's impact on major population centers caused widespread interruption to critical water/electrical services and also caused 159 deaths (72 direct, 87 indirect). Sandy also caused the New York Stock Exchange to close for two consecutive business days, which last happened in 1888 due to a major winter storm.$88.5 CI159
Northeastern Winter Storm
October 2011
Winter StormOctober 29, 2011October 30, 2011Winter storm impacts northeastern states including Connecticut, Massachusetts, New Hamsphire, New York, New Jersey and Pennsylvania.$1.3* CI1

Wind damage in coastal NC, VA, and MD was moderate with considerable damage resulting from falling trees and power lines, while flooding caused extensive flood damage across NJ, NY, and VT. Over seven million homes and businesses lost power during the storm. Numerous tornadoes were also reported in several states further adding to the damage.$18.8 CI45

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.
