2022_BDD_histogram_monthly_multi-events.png

This graph shows the percent frequency of a given month having at least one billion-dollar disaster (light pink bars), 2 or more events (medium pink bars), 3 or more (red), 4 or more (darker red), or 5 or more (darkest red). Billion-dollar weather and climate disasters occur in all months, but the spring and summer (March–Aug) are the time when multiple, concurrent disasters are likely. A second maximum occurs in the Fall driving by tropical cyclones. Screenshot from the NCEI Billion-dollar Disasters webpage.
