There is also a high frequency of inland flooding events that 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 mostly focused in the Southern and Plains states where there are billions of dollars in agriculture and livestock assets. Crop freeze events have become more sporadic since the early s, but these events can still cause considerable damage in the fruit-producing states of California, Florida, and other southeastern states such as Georgia and South Carolina.
Severe local storm events are common in the Plains and into the Ohio River Valley states. Tropical cyclones are the most costly disaster we assess that create impacts from Texas to New England, but also include many inland states, often as a result of extreme rainfall and inland flood damage.
This map depicts the number of times each state was part of a billion-dollar weather or climate disaster since , regardless of hazard type. Note that each disaster did not necessarily cause one billion dollars in damages in an individual state to be included in this total.
In total, from —, the U. The South has also suffered the highest cumulative damage costs, reflecting the diversity, frequency, and severity of weather and climate events impacting the region. Each state has been affected by at least 1 billion-dollar disaster since Texas has experienced the highest number of events and is one of the few states that have been impacted by all seven types of the billion-dollar disasters we analyze. This map of U. In addition to the highest number of billion-dollar disasters experienced, Texas also leads the U.
In , the Midwest states suffered extensive losses from the worst flooding since A map of U. Darkest reds show states with highest percent damages, which are found in South Dakota and Nebraska, which suffered from significant flooding in spring and summer Visit the page to create your own summaries or download source data.
In , NCEI will continue to incorporate new layers and filters that offer added flexibility to the online tools for additional context and analysis. For additional context on data sources, methods, metrics and caveats see: Calculating the Cost of Weather and Climate Disasters. Due to a typo, an earlier version of this article cited the number of events as The correct number is I'm posting a response from blog author Adam Smith, which he sent via email. He echoes Deke's comment:. Yes, from through , we have sought to incorporate all sub-billion dollar events at the time when they occurred e.
Depending on what you want to do with the data, you would likely have to make additional adjustments. If you wanted to be able to say exactly how much each factor contributed, then you'd definitely have to account for the greater development intensity today compared to earlier decades. But that kind of attribution is beyond the scope of the analysis. The annual billion-dollar disaster update is simply an inflation-adjusted score-card that can be used to compare total costs from one year to another.
But if they did, they would have to account for all those variables you mentioned, and more! Those data are shown in the fourth graphic of the post. Yes and no. These billion-dollar events account for physical damage to residential, commercial and government buildings and their contents. It also accounts for time element losses like business interruption and loss of living quarters, damage to vehicles, boats, offshore energy platforms.
Also, damage to public infrastructure like roads, bridges, levees, dams, etc. However, we do not account for damages or losses to natural capital, mental or physical health care related costs or the statistical value associated with loss of life.
So these losses should be considered a conservative estimate to what is truly lost but cannot be completely measured. The Billion-dollar disaster section of the NCEI website has lots of options for sorting and filtering data.
Start here:. Use the blue tabs across the top of the page to access the maps. Also, each of these tabs offers an option to sort by region or state: time series, Climatology, Summary stats, and events.
Add new comment. Rest in peace to everyone who Permalink. Rest in peace to everyone who perished in these disasters. And I think it is pretty cool that you keep track of billion dollar diasters.
In your billion dollar weather disasters blog In other words 1 billion in was a higher cost-bar to reach than it is today for an identical disaster. A correct comparison would be to count the number of said disasters relative to effective the same year loss value for all disasters in that year rather than just adjust the cost of billion dollar disasters already documented for any year.
In recent years, this has led to events added from earlier in the time series. He echoes Deke's comment: Yes, from through , we have sought to incorporate all sub-billion dollar events at the time when they occurred e. Shouldn't the losses also be Permalink. Shouldn't the losses also be adjusted for the increase in the quantity of capital stock over the last 40 years?
There are more structures, equipment and durable goods in than in subject to losses? RE: Shouldn't the losses also be Permalink. Other factors Permalink. This would mean more assets are available for damage in recent years. A factor that could be influencing in the opposite direction is that prevention and response technology is likely improving over time e.
For more in-depth analysis, the following report offers the latest summary on the U. Billion-Dollar Weather and Climate Disasters All Years present.
Last Year Last 3 Years Last 5 Years View summary data in Summary Stats. All Disasters. Severe Storm. Many people think that this problem only occurs near the coast or next to rivers.
However, it is happening all across the US, all the time. Flooding events like flash, surge, and storm are becoming more severe, more intense, and more damaging. We know that rainstorms are getting more intense. Since , the ocean has risen 6. This may not sound like much, but it only takes inches to stop gravity-fed drainage systems from working or for water to creep into our streets. When you pave over a natural surface, the water has to go somewhere else.
Extensive development has dramatically decreased natural drainage, creating excess runoff, increasing flood risk for millions of Americans. Here you can see the massive increase in paved areas in Houston over 20 years.
Less natural surface means fewer places the water can go. Flood standards in many developed countries far exceed the NFIP 1 in standard. For example, Japan and the Netherlands use 1 in 10,year protection for coastal works and densely populated areas. The story gets worse. Recently a group of scientists and the First Street Foundation came together to build a better flood model.
