California Mega Flood Predicted, State Expected to Have Extreme Weather in Coming Decades, Study Says

California is in for some wild weather, featuring a "whiplash" of drought and rain, within the coming decades, according to a new study.

In fact, the weather is predicted to be so severe that by 2060, the state should expect to get slammed by a flood as devastating as the notorious 1862 "Great Flood," authors of the study, which was published in the journal Nature Climate Change, claim.

"We may be going from a situation where an event as big as 1862 was unlikely to occur by the end of the century to a situation where it may happen more than once," Daniel Swain, lead study author and climate scientist at the University of California, Los Angeles said in a statement.

Despite the predicted extreme bouts of precipitation, the state's average annual rainfall won't change much. That's because the dramatic shifts between dry and wet periods will cancel each other out.

"These are actually huge changes occurring; they're just on opposite ends of the spectrum," Swain said. "If you only look for shifts in average precipitation, you're missing all of the important changes in the character of precipitation."

Swain and his colleagues used a climate model which predicted a 25 to 100 percent increase in whiplash events throughout the Golden State. If such changes occur, California could face serious problems in regards to water storage, conveyance and flood control infrastructure, the authors wrote in their published paper.

Their conclusions are based on the assumptions that man-made greenhouse gas emissions will continue to rise.

"Such a future can be partially, but not completely, avoided" Swain said, Reuters reports.

But in order to prepare for the worst, he advises the state exercise better floodplain management by intentionally flooding the regions to soak up rain water.
