Billion-Dollar Weather and Climate Disasters: Mapping
To better visualize the spatial dimensions of Billion-dollar weather and climate events, below is an interactive event frequency mapping tool. This interface provides a customizable range of years and disaster types, to help visualize how disaster costs change over space and time. A dynamic summary of the Billion-dollar disaster events is also refreshed as the map selection is updated.
Each geographic region of the U.S. faces a unique combination of weather and climate events. The map above reflects the frequency of the billion-dollar disaster events impacting each state (i.e., does not mean that each state shown has suffered $1 billion in losses for each event). Each disaster type has a distinct footprint of impact over time.
For example, wildfire impacts are most common west of the Plains states and in several Southeastern states. The highest frequency of inland flood (i.e., non-tropical) events often occur in states adjacent to large rivers or the Gulf of Mexico, which is a warm source of moisture to fuel rainstorms. Drought impacts are most focused in the Southern and Plains states where crop and livestock assets are densely populated. Severe local storm events are common across the Plains, the Southeast and the Ohio River Valley states. Winter storm impacts are concentrated in the Northeastern states while tropical cyclone impacts range from Texas to New England but also impact many inland states. In total, the U.S. South/Central and Southeast regions experience a higher frequency of billion-dollar disaster events than any other region.
