Extreme weather is on the rise. July 2023 was the hottest month ever recorded. The heat wave caused at least 147 deaths in the United States, many of them in Arizona and Texas. According to the Centers for Disease Control and Prevention, extreme heat kills about 1,220 people in the U.S. annually.
July also saw the highest ever ocean surface temperatures — and warm oceans are known to fuel tropical storms and hurricanes. As the water warms the surface air, the hot air provides storms with more energy, which enable stronger winds and have the potential to cause widespread destruction once they hit land. (Read about the most hurricane-vulnerable counties in America.)
To identify the states with the most dangerous weather, 24/7 Wall St. reviewed “Summary of Hazardous Weather Fatalities, Injuries, and Damage Costs by State” for 2020, 2021, and 2022 — the latest three years for which this data is available — from the National Weather Service. We calculated weather-related deaths per person by dividing total fatalities in each state over the three years by each state’s total population.
Weather events considered by the NWS include cold, floods, heat, lightning, tornadoes, tropical cyclones, wind, and winter storms. Total population statistics are annual averages for 2022 from the U.S. Census Bureau’s 2022 American Community Survey.
From 2020 to 2022, Arizona was by far the state with the most weather-related deaths. Heat-related fatalities accounted for 603 of the 627 deaths in the state during that period. Arizona had over three times the number of fatalities than the next state with the most dangerous weather, Texas. While there were 55 heat-related deaths in Texas, cold-related deaths reached 78 in 2021 alone. A record-breaking winter storm and deep freeze hit the state in February 2021, leaving much of southern Texas without electricity.
Other states with the most dangerous weather include Oregon, which recorded 119 deaths due to heat in 2021; Florida, which had 91 deaths as a result of tropical cyclones in 2022; and Kentucky, where tornadoes left 74 dead in 2021, and flooding caused 41 deaths in 2022. (These are the 20 states with the biggest risk of flooding.)
