The "1,000-year" rain dumped more than 20 inches of rain over some parts of South Carolina over the weekend, and forecasters predict the downpour won't stop until Tuesday.

Here's what the flooding looked like Friday on Ocean Boulevard in Myrtle Beach, South Carolina. 

And this is what Garden City Beach, South Carolina, an area just south of Myrtle Beach looked like on Friday as Hurricane Joaquin started making its way north.

At least six people have died in the storm since the flooding began. Some areas have flooded so bad that cars are almost completely submerged, like this one in Columbia, South Carolina.

Home to the University of South Carolina, Columbia recorded more than 10 inches of rain. The university was closed on Monday and the city warned residents to boil their drinking water because of a water treatment plant breach caused by the flooding. 

The flooding was so bad that the city implemented a 6 p.m. curfew for Columbia residents.
