Record-Breaking Heatwaves and Billion-Dollar Disasters in the U.S. – June 2024
In June 2024, the United States experienced unprecedented weather extremes, highlighting the urgent need for climate action. Record-breaking heatwaves, devastating wildfires, catastrophic flooding, and the earliest recorded Category 4 hurricane in the Atlantic combined to create one of the most severe weather months on record.
Unprecedented Heatwaves The average temperature for the contiguous U.S. in June was 71.8°F, ranking as the second warmest June in 130 years. Approximately 24 million people across the West, South, and Northeast experienced their warmest June for overnight temperatures. Arizona and New Mexico saw their hottest June on record, with temperatures exceeding 50°C in some areas. These extreme conditions created life-threatening situations and overwhelmed healthcare systems.
Severe Wildfires and Flooding The South Fork fire in New Mexico, one of the most devastating in the state's history, burned over 17,000 acres and destroyed approximately 1,400 structures. Meanwhile, catastrophic flooding in the Midwest, following days of heavy rains, led to widespread evacuations and significant damage, including the partial failure of the Rapidan Dam in Minnesota.
Historic Hurricane Beryl On June 30, Hurricane Beryl became the earliest Category 4 hurricane on record in the Atlantic, marking a significant milestone in the 2024 Atlantic hurricane season. Beryl's unprecedented early formation underscores the increasing intensity and unpredictability of hurricanes due to climate change.
Billion-Dollar Disasters June saw the confirmation of four new billion-dollar weather and climate disasters, bringing the 2024 total to 15. These events included two major hailstorms, a severe weather outbreak, and a tornado outbreak, resulting in over $37 billion in damages and at least 106 fatalities. Since 1980, the U.S. has experienced 391 such disasters, with total costs exceeding $2.755 trillion.
Temperature and Precipitation Patterns June temperatures were above average across most of the contiguous U.S., with significant warmth in Alaska as well. Precipitation was below average in many areas, leading to drought conditions in the Southeast and Mid-Atlantic. Conversely, the Upper Midwest and Southwest experienced above-average rainfall, causing severe flooding.
Drought Conditions As of early July, about 19% of the contiguous U.S. was experiencing drought, a 6% increase from the end of May. Drought intensified across the Southeast, Mid-Atlantic, and portions of the Ohio Valley and northern Plains, while some relief was seen in the Southwest and southern Florida.
Conclusion The extreme weather events of June 2024 serve as a stark reminder of the urgent need for comprehensive climate action. Policymakers, environmentalists, and the general public must work together to mitigate the impacts of climate change and build resilient communities.
June 2024 saw record-breaking heatwaves across several U.S. regions, contributing to four new billion-dollar weather and climate disasters. Key impacts included extreme temperatures, significant wildfires, catastrophic flooding, and the earliest Category 4 hurricane recorded in the Atlantic. The contiguous U.S. experienced its second-warmest June, while Alaska had its sixth-warmest. Precipitation was below average in many regions, causing drought, but above average in others, leading to flooding. The year-to-date total of billion-dollar disasters now stands at 15.
