There was also severe damage to homes, businesses and vehicles particularly in Cedar Rapids, Iowa. The GOES-East satellite captured this IR image of clouds and lightning as the derecho moved eastward from Iowa to Indiana. This derecho caused widespread damage to millions of acres of corn and soybean crops across central Iowa.Ī line of severe thunderstorms produced a widespread, fast-moving windstorm called a derecho on August 10, 2020. The states most affected included Iowa, Illinois, Minnesota, Indiana, and Ohio. Historic Midwest Derecho (August 2020): $11.0 billion, 4 deathsĪ powerful derecho traveled from southeast South Dakota to Ohio, a path of 770 miles in 14 hours producing widespread winds greater than 100 mph. There were additional impacts to surrounding states including Texas, Mississippi, and Arkansas. Laura also had highest landfall wind speed to impact the U.S. Laura was the strongest hurricane (by maximum sustained wind speed at landfall) to hit Louisiana since the 1856 Last Island hurricane. NOAA GOES-East image from the NOAA satellite team. By 2020, it had risen again to about 85% of all disaster-related costs, or $1.875 trillion out of $2.215 trillion.Ĭategory-4 Hurricane Laura made landfall during the early morning hours of August 27, 2020, at Cameron, Louisiana. Winds up to 150 mph and storm surge in excess of 15 feet caused heavy damage along the coast and inland to the city of Lake Charles. From 1980-2000, about 75% of all disaster-related costs were due to billion-dollar disasters, and by 2010, the percentage had risen to about 80%. losses from hurricanes and wildfires over the last four years (2017-2020) have further skewed the total distribution of extreme weather costs. In particular, the historically large U.S. weather and climate events (NCEI Munich Re), and they are becoming an increasingly larger percentage of the total damage costs from weather-related events at all scales and loss levels. However, these extreme events do account for the majority (>80%) of the damage from all recorded U.S.
weather and climate disasters, only those associated with events in excess of $1 billion in damages. It is important to keep in mind that these estimates do not reflect the total cost of U.S. The average number and cost (CPI-adjusted) of billion-dollar disasters is on the rise. In total, it is clear that 2020 (red line below) stands head and shoulders above all other years in regard to the number of billion-dollar disasters. California more than doubled its previous annual record for area burned (last set in 2018) with over 4.1 million acres. wildfire season, which burned more than 10.2 million acres. Not to be left out, many central states were impacted by a historically powerful derecho on August 10, which caused impacts comparable to an inland hurricane. And 7 of the 12 became billion-dollar disasters-also a new record. Of these 30 storms, a record 12 made landfall in the United States. experienced a record-breaking number of named tropical cyclones (30), eclipsing the record of 28 set in 2005, the year of Hurricane Katrina. In 2020, the United States experienced record-smashing 22 weather or climate disasters that each resulted in at least $1 billion in damages, including a record 7 linked to landfalling hurricanes or tropical storms. The cumulative cost for these 285 events exceeds $1.875 trillion. (All cost estimates are adjusted based on the Consumer Price Index as of December 2020). has sustained 285 weather and climate disasters where the overall damage costs reached or exceeded $1 billion. The 22 events cost the nation a combined $95 billion in damages.Īdding the 2020 events to the record that began in 1980, the U.S. The billion-dollar events of 2020 included a record 7 disasters linked to tropical cyclones, 13 to severe storms, 1 to drought, and 1 to wildfires. There were 22 separate billion-dollar weather and climate disasters across the United States, shattering the previous annual record of 16 events, which occurred in 20.
MOST RECENT HURRICANES 2014 UPDATE
NOAA’s National Centers for Environmental Information (NCEI) has released the final 2020 update to its Billion-dollar disaster report ( officially confirming what communities across the nation experienced first-hand: 2020 was a historic year of extremes.
