Hurricane Costs (2024)

The year 2023 broke multiple weather and climate records. Earth had its warmest July on record. July also set a record for the highest monthly sea surface temperature anomaly (+1.78°F or +0.99°C) of any month in NOAA’s 174-year record. According to the NOAA National Centers for Environmental Information’s Global Annual Temperature Outlook, it is almost certain (over 99 percent) that the year 2023 will rank among the five warmest years on record, with a nearly 50-percent probability that 2023 will rank warmest on record.

In August, Tropical Storm Hilary made history as the first tropical storm to hit Southern California in 84 years. Rainfalls for Hilary broke virtually all daily rainfall records for the area.

In total, 25 weather and climate disasters with losses exceeding $1 billion each affected the U.S. in 2023. The combined total cost of these 2023 disasters is $81 billion. Only one other year (2017) had more billion-dollar disasters in the first six months, and 2023 was second only to 2021 for total damage costs through the first half of any year since 1980.

In 2023, flooding events alone caused a total of almost $7 billion in damages in the U.S. Some specific examples of flooding and other extreme weather events throughout the country include the following:

Northeast, East Coast: August 2023 – More than 1,000 reports of high wind, severe hail, or tornadoes across many Northeastern and Eastern states. August 7 was a prolific day of severe weather, with damage reports from New York down to Georgia. Total costs: $1.6 billion.

Northeast: July 2023 – Severe storms brought devastation and flooding to portions of the Northeast, as areas reported up to eight inches of rain within a 24-hour period. Montpelier, Vermont, received a record-breaking 5.28 inches of rain; early estimates put the flood damage in West Point, New York, at more than $100 million. Total costs: $2.2 billion.

Central, Gulf, South, and Southeast: June 2023 – Severe storms produced over 1,000 reports of weather-related damage across Oklahoma, Texas, Mississippi, Georgia, Florida, Arkansas, and Ohio. Total costs: $3.8 billion.

West Coast: Late 2022 through early 2023 – Numerous atmospheric rivers in continuous succession caused severe flooding, record snowfall, and copious rainfall across California between late-December and March 2023. Total costs: $4.6 billion.

Southeast: Hurricane Idalia – Idalia was the strongest hurricane to hit Florida’s Big Bend region in more than 125 years. Idalia produced 5 to 10 inches of rainfall across the Big Bend region of Florida and southeastern portions of Georgia and the Carolinas. Total costs: $3.6 billion.

2020 set a new record for events, with 22 billion-dollar weather and climate disasters—shattering the previous annual record of 16 events in 2011 and 2017.

There were 13 severe storms, seven tropical cyclones, one drought, and one wildfire event in 2020, for a total cost of $95 billion. These events resulted in the deaths of 262 people.

The cumulative costs of the 16 separate billion-dollar weather events in the U.S. in 2017 was $306.2 billion, breaking the previous cost record of $214.8 billion (2005). The 2017 Atlantic hurricane season was among the most intense ever recorded. Record-breaking statistics, in addition to costs, include the following:

Hurricane Harvey: Harvey was the most significant tropical cyclone rainfall event ever recorded in U.S. history, both in scope and peak rainfall amounts. The highest storm total rainfall report from Harvey was 60.58 inches. Prior to Hurricanes Irma and Maria, Harvey became the deadliest U.S. hurricane in terms of direct deaths since Sandy (2012) and the deadliest hurricane to hit Texas since 1919. It was the first category 4 hurricane to make landfall in Texas since 1961, and the first category 4 to make landfall in the U.S. since 2004. Harvey lasted 117 hours, beating the previous record for duration of Hurricane Fern in 1971.

Hurricane Irma: With maximum winds of 185 miles per hour, Irma became the strongest storm on record to exist in the Atlantic Ocean outside of the Caribbean and Gulf of Mexico. It sustained those maximum winds speeds for 37 hours and spent three consecutive days as a category 5 hurricane—making it the longest of any cyclone in the world since 1932 to maintain that intensity. The occurrences of Harvey and Irma—making landfall within two weeks of each other—were the first time in recorded history that two category 4 or higher hurricanes struck the U.S. mainland in the same year.

Hurricane Maria: Maria was the first category 5 hurricane ever to make landfall in Dominica, and the strongest hurricane to make landfall in Puerto Rico since 1928. It was the deadliest of 2017’s three major storm, with over 2,900 fatalities.
