Powerful storm causes havoc and adds snow

LOS ANGELES — The latest and most powerful in a series of three winter storms slammed into California on Sunday, flooding roads, forcing evacuations in communities near burn areas and adding more snow in mountains from the Sierra Nevada to the San Bernardino Mountains. The state’s biggest reservoirs are brimming and more rain is on the way.

The National Weather Service issued flash flood warnings for a large swath of the region. Numerous roads around Southern California were flooded by intense bursts of rain.

At Disneyland, heavy rains poured and a flash flood warning was issued as the sparse number of guests hid under the monorail.
