[2] The remains of the tropical cyclone sat and spun over eastern Texas for several days before moving eastward just inland of the Gulf coast.

[3] A large Category 3 hurricane at landfall along the southeast tip of Louisiana, the strong northerly flow behind Katrina caused breaks and failures in the levees that protected the lower Ninth Ward and along other canals in New Orleans, flooding 80 percent of the city for nearly a month.

In New Hampshire, the Monadnock region was affected, with Alstead among the hardest hit as 300 mm (12 in) of rain fell within 30 hours, allowing this month to be the wettest in the history of the Granite State.

[5] Prolonged rainfall fell across Hawaii between February 19 and April 2, 2006, as upper-level cyclones kept closing off northwest of the archipelago, virtually eliminating their normal trade winds, and bringing some of the wettest conditions seen in the state since March 1951.

The heavy rain event of March 1 to 3 brought severe flooding to the east-facing slopes of the Koolau Range in Oahu, with 571 mm (22.47 in) falling in two days at Punalu'u.

As much as 356 mm (14 in) of rain fell over north Kauai, forcing the closure of Kuhio Highway at the Hanalei Bridge for the second time in 24 hours.

The Kauai Marriott Resort suffered significant damage due to the overflow of Keonaawanui Stream during the early morning hours of March 11.

In 2009, a record flood caused extensive damages along the Red River of the North, affecting the areas of Fargo-Moorhead, Wahpeton-Breckenridge, and Grand Forks between the Minnesota–North Dakota border, as well as Winnipeg and its surroundings in Manitoba, Canada.

According to the National Weather Service, in the second half of the month of May 2011, almost a year's worth of rain fell over the upper Missouri River basin.

Heavy rain fell after moist air surged ahead of a strong cold front and low-pressure system, leaving many rivers swollen.

[27] By June 1, the outflow from Coralville Reservoir had been increased to 18,000 cubic feet per second with the control gates fully opened, putting an estimated 50–60 structures at risk of inundation.

[31] During the week starting September 9, a slow moving cold front stalled over Colorado, clashing with warm humid monsoonal air from the south.

The town of Lyons in Boulder County was isolated by the flooding of the St. Vrain River,[34] and several earth dams along the Front Range burst or were overtopped.

[37][38] On April 29–30, 2014, a slow-moving cold front associated with a tornado outbreak in the Deep South dumped a record setting amount of rainfall, inundating the western Florida Panhandle and Southwest Alabama.

[59] Most notably, the town of Wimberley, Texas, along with a significant portion of Hays County was devastated when the Blanco River rose to almost 30 feet above flood stage overnight.

[61] Heavy rain from the remnants of Hurricane Linda fell over southern Utah, causing flash floods in Zion National Park and the town of Hildale.

In the neighborhood of Golden Meadows in Bossier City, the rapid rainfall overwhelmed storm drains and stranded people in their homes with up to four feet of water in some areas.

[73] Significant flash flooding affected the Baltimore Metropolitan Area, and especially hard hit was Ellicott City where up to six inches of rain fell within two hours.

From August 23–28, 2017, Potential Tropical Cyclone Ten's precursor stalled over Florida, causing the worst flooding the state had seen in at least 20 years.

[78] Less than two weeks later, Hurricane Irma made landfall in southwestern Florida on September 10, bringing additional flooding to the region, causing significantly more damage in the state.

[94] Lane's peak rainfall total was also the second-highest recorded from a tropical cyclone within the United States, surpassed only by Hurricane Harvey in the preceding year.

[100] In March 2021, a cut off upper-level low brought torrential rainfall to Hawaii, triggering severe flooding across the islands of Oahu, Maui, and Kauai.

After the deluge had passed, it was reported that there had been no fatalities, but that damage occurred in Georgia, Texas, Alabama, Mississippi and Virginia, and that debris must be cleaned up when it is safe to do so, and the waterline has receded to manageable levels.

The flooding was worsened by ground softening caused by recent and ongoing wildfires in Arizona, and in the United States, which in turn, were sparked by a heatwave and drought.

[113][114] On the morning of August 21, storms riding along a stationary front in western Middle Tennessee produced widespread flash flooding across the counties of Stewart, Houston, Dickson, Humphreys, and Hickman.

[153] Scientist Kevin Trenberth declared that "the interaction between the warming ocean and the overlying atmosphere (...) is producing these prodigious rainfalls that have occurred in so many places around the world recently".

Multiple rounds of heavy rainfall also moved through the region as a result of favorable precipitable water values, convective instability, and low-level winds.

Flooding also occurred across numerous towns and municipalities across New Jersey and Connecticut, causing the Housatonic River to swell in western portions of the latter state.

Further north around Myrtle Beach, South Carolina, a flash flood emergency was issued with some areas receiving over 13 in (330 mm) of rain.

Prior to the storm, New York City used drones to notify residents of low lying areas of the impending flooding as part of a new warning system developed after Hurricane Ida.
