Hurricane Harvey brings devastation to Texas: By the numbers

Harvey was the worst storm to hit Texas in more than 50 years.

— -- Hurricane Harvey tore through the state of Texas over the weekend, leaving behind a trail of devastation and an ongoing fight for survival in Houston as residents there continue to battle rising flood waters.

Harvey, a category 4 hurricane, was the strongest storm to hit Texas since the 1960s. The storm devastated coastal communities in its eye, and then delivered a blow to Houston, the country’s fourth-most populous city, with record rainfall.

Here is a snapshot of Hurricane Harvey by the numbers:

The storm

In the last two days, 24.44 inches of rain has fallen in Houston, the NWS reported on Monday. The rainfall from Harvey has already made this August the wettest month on record for Houston. The rainfall as of Monday afternoon that has inundated Harris County, Texas, is equal to approximately 732 billion gallons of water, which is enough to fill more than 1 million Olympic-size swimming pools.

ABC News meteorologists expect up to 50 inches of rain to accumulate in the southeastern part of Texas by Wednesday as a result of the storm.

Harvey has so far affected about a quarter of the Texas population, or 6.8 million people in 18 counties, according to The Associated Press.
