Harvey by the Numbers—So Far

As Houston begins to emerge from beneath the damage left behind by Hurricane Harvey's torrential rains, early assessments are calling the days-long weather event "the worst U.S. flood storm ever." Below, some shocking statistics that illustrate the extent of Harvey's destruction:

1 trillion

Gallons of water that fell in Harris County over four days

24.5 trillion

Total gallons of water dumped on the Gulf Coast by Hurricane Harvey, with 19 trillion in Texas and 5.5 million in Louisiana

300,000 to 500,000

Cars destroyed by floodwaters, with other estimates placing the number closer to 1 million—more vehicles destroyed than any other natural disaster in U.S. history


Refineries closed or at risk of closing due to Harvey, accounting for 4.6 million barrels a day of fuel production, or 25 percent of the total U.S. refining capacity

400,000 acre-feet of water

The amount contained by Addicks and Barker dams during the storm, about the same amount of water that goes over Niagara Falls in 10 days

40 inches

Peak accumulation of rainfall during Allison, the costliest tropical storm on record in the U.S., which caused over $9 billion in damages in 2001

51.88 inches

Peak rainfall accumulation during Hurricane Harvey, making it the wettest tropical cyclone on record in the contiguous U.S.

49.77 inches

Houston's annual average rainfall amount

$12.5 billion

Damages caused by Hurricane Ike in 2008

$30 billion

Estimated damages caused by Hurricane Harvey


Combined insurance claims received so far by Farmers Insurance and State Farm from affected Houstonians


Homes estimated to have been flooded by Hurricane Harvey


Houstonians estimated to be displaced from their homes


Houstonians who had to be rescued from their flooding homes
