El Niño is expected to bring heavy storms throughout the winter and cause serious flooding on the West Coast. Currently 50 to 70 percent of residents in high-risk flood areas aren't covered -- and it takes 30 days to get approved.

"If there was ever a time to buy flood insurance, this is the time," said FEMA's deputy associate administrator for insurance and mitigation Roy Wright.
