Hurricane Rapid Intensification

The document details how rising sea surface temperatures, driven by human-caused climate change, are increasing the frequency and intensity of rapid intensification in tropical cyclones. It highlights that 70% of billion-dollar tropical cyclones in the U.S. since 1980 underwent rapid intensification, contributing to over $1.4 trillion in damages and nearly 7,000 deaths.

• Rapid intensification is defined as a tropical cyclone's maximum sustained winds increasing by at least 30 kt (approximately 35 mph) within a 24-hour period. Between 1980 and 2023, 177 landfalling Atlantic tropical cyclones met this threshold, with 22% (39 storms) experiencing 'extreme rapid intensification' of at least 50 kt in 24 hours.
• There is a strong correlation between rapid intensification and high economic losses in the U.S. Of the 63 tropical cyclones causing at least $1 billion in damage from 1980 to July 2024, 70% (44 storms) underwent rapid intensification. The five most expensive hurricanes since 1980—Katrina, Harvey, Ian, Maria, and Sandy—all had maximum 24-hour intensification rates between 40-70 kt.
• Human-caused climate change is increasing the likelihood of intense storms. Since 1979, the global probability of a tropical cyclone becoming a major hurricane (Category 3 or higher) has increased by approximately 5% per decade. In the North Atlantic, the number of storms intensifying from Category 1 or weaker to a major hurricane more than doubled between 2001-2020 compared to 1971-1990.
• Global sea surface temperatures have been continuously hotter than any period on record since April 2023. This ocean heat contributed to a highly active 2024 Atlantic hurricane season and made the warm waters that fueled Hurricane Beryl up to 400 times more likely.
• While the frequency of landfalling hurricanes in the continental U.S. remained stable from 1900-2017, economic losses have risen due to increased exposure from population growth and regional wealth along the East and Gulf Coasts. Additionally, rainfall flooding caused 57% of all U.S. tropical cyclone deaths between 2013 and 2022.
