Hurricanes, forest fires, tornadoes, floods: whatever the risk, here’s how to be more prepared for the elements | Weather
Flooding is a huge problem in America and is only getting worse as global warming increases the frequency and strength of tropical storms and hurricanes, and the warmer atmosphere holds more water, resulting in more precipitation. . Warmer temperatures also trigger winter snowmelt faster and earlier.
Flooding in the United States is expected to cause some $ 20 billion in damage this year and cost up to $ 32 billion by 2051, according to First Street research. Sundae examined the top 10 cities in the country with the most properties at risk of flooding, using 2020 data from the The First Street Foundation’s First National Flood Risk Assessment. Using First Street’s flood risk model based on existing environmental and weather data, cities are ranked based on the percentage of properties at risk out of total properties. Projected data is also included for the properties at risk in 2050 and the projected change over 30 years.
As the country’s urban areas develop, a more impermeable pavement creates runoff and hinders the soil’s ability to absorb water. Development encroaches on wetlands and forests that served as barriers and prevention of natural floods. Aging and poorly maintained infrastructure exacerbates urban flooding, and the construction of dikes and canals and the loss of riparian vegetation alter the natural flow of rivers, fueling their potential to overflow their banks.
