Since 1980, the National Oceanic and Atmospheric Association (NOAA) and the National Centers for Environmental Information (NCEI) have been collecting data on catastrophic weather events that incur costs of one billion dollars or more (usually more). The dashboard below uses public NCEI data to visualize the number and cost of billion-dollar disasters by state over the past five years. The data visualization below the dashboard includes trends over time since 1990. Feel free to read more about NCEI's methodology here.
