Catastrophic flooding has swallowed swaths of southern Louisiana in a deluge that the governor calls “unprecedented.” The breadth of the destruction is hard to imagine.
Here's what the disaster looks like, by the numbers:
6.9 trillion: Gallons of rainfall in one week
About 6.9 trillion gallons of rain pummeled Louisiana between August 8 and 14. That's enough to fill more than 10.4 million Olympic-size swimming pools.
31.39: Inches of rain in one day
500 years: Expected frequency of a flood this big
The likelihood of a flood this catastrophic in the Baton Rouge area is about once every 500 years. But, according to the National Oceanic and Atmospheric Administration, since last August, five other floods around America have been considered "500-year floods."
60,000 Homes damaged
So far, more than 60,000 homes have been reported damaged but the damage may be much greater as the water recedes and people return to their homes. Two huge problems are mud and mold, which can lead to respiratory problems for children and the elderly.
20,000: People rescued
Members of the Coast Guard and National Guard, along with emergency responders and regular civilians, helped take more than 20,000 residents to safety. 1,000 pets have also been rescued.
106,000: Households registered with FEMA
More than 106,000 individuals and households have registered with FEMA for assistance as survivors are in need of temporary rental help, essential home repairs and other disaster-related needs. More than $55 million has been approved to help survivors.
13: Deaths across the state
$30 million: The estimated cost of the flood so far
That number will definitely rise into the hundreds of millions, if not billions, of dollars.
