In October 1995, the Southeast endured the wrath of Category 3 Hurricane Opal. The hurricane ravaged Florida, Alabama, western Georgia, eastern Tennessee, and the western Carolinas with its gusting winds and flooding. Most of the damage came from storm surges of up to 10 to 15 feet along the coastal areas of the Florida panhandle. More than 1,300 homes and 1,000 boats were destroyed or extensively damaged. Left in the hurricane's wake was a massive $7.87 billion bill for such things as destroyed water and sewer systems, roadways, and phone and electric utilities.

Severe drought and heat conditions in the Western U.S. led to devastating wildfires in the region in 2021. Roughly 7.7 million acres were burned, and the particularly dry conditions made the fires extraordinarily difficult to put out. Between the destruction of property and funds needed to battle the megablazes, the 2021 wildfires were some of the costliest in U.S. history. In addition to the ecological and economic damages, smoke from the fires is thought to have mingled with the debilitating respiratory effects of COVID-19 to increase infections and deaths by the thousands.

At the end of August 2017, Category 4 Hurricane Harvey made landfall near Rockport, Texas, spawning more than 30 tornadoes and heavy winds, and dumping 30 to 50 inches of rain on 13 million people in Texas, Louisiana, Mississippi, Tennessee, and Kentucky. In Houston—the nation's fourth-largest city—at least 3,900 people still had no power almost three weeks after the storm, and national gas prices rose as 25% of oil and gas production was shut down in the region. At one point, 75% of Harris County, which encompasses Houston, was under 1.5 feet of water. Massive flooding displaced over 30,000 people and damaged or destroyed over 200,000 homes and businesses.

On Aug. 29, 2005, Hurricane Katrina—the costliest and one of the deadliest disasters in U.S. history—made landfall near Grand Isle, Louisiana, as a Category 3 storm with 127 mph winds and severe storm surges, some in excess of 30 feet. Katrina affected 90,000 square miles and at least eight states, with most of the damage occurring in Mississippi, Alabama, and Louisiana—particularly New Orleans. At least 50 levees failed in New Orleans resulting in devastating mass flooding. By the end, 1,833 people had been killed, including 1,577 in Louisiana, and more than 1 million people had been displaced. Two of the region's biggest industries—oil and gas—suffered greatly, and tourism to the coastal communities died as infrastructure continued to erode. From April 2000 to July 2006, New Orleans' population decreased by more than half.
