The United States is expected to face the worst flooding on record.
The U.S. Geological Survey (USGS) is predicting that the worst will hit the Houston metro area, home to more than a quarter of the country’s population.
According to the USGS, the river is expected “to crest at 2,900 feet, but it is expected that some areas will experience significant flooding during this time,” which is why the flood warning is extended for the Houston area until March 14.
The flood warnings will be in effect through March 14, the USG said in a statement.
But according to the Weather Channel, which is the weather bureau for Houston, there are a number of cities that could be impacted by the flooding, including Houston, San Antonio, Dallas, and San Francisco.
In Houston, the average annual rainfall is around 2,000 millimeters, according to Weather Channel.
According to USGS estimates, the Houston River has recorded 784,000 acre-feet of rain over the last five years.
For comparison, the St. Louis River, which runs through Kansas City, Missouri, has recorded more than 6,000,000 cubic feet of rain per year.
The USGS expects the Houston-Galveston Bay region to be the most heavily impacted area of the flood, with the heaviest rainfall expected to occur in Houston, where it could exceed the area of New Orleans.
The Houston metro region has about 2.4 million people, and the storm surge expected in the Houston region could be up to 4 feet.
The Weather Channel reports that Houston residents who are evacuating will need to get off of their properties to avoid the flooding.
According the US Geological Survey, Houston was already one of the driest cities in the country during the 2010 Super Bowl.
The storm surge is expected in Houston to exceed 5 feet, according the US Weather Channel
