SAN FRANCISCO - Contra Costa County Fire Protection District says the cause of a four-vehicle crash in Walnut Creek Thursday afternoon appears to be weather related. Five people were taken to the hospital and one patient is in critical condition. 10 passengers from a county bus had to be evaluated, officials said.

Fire officials said they were at the scene of the multi-vehicle accident at the intersection of Ygnacio Valley Road and Oakland Boulevard at shortly after 4 p.m. They warned of the wet roads and high winds associated with the latest atmospheric river.

The multi-casualty incident was cleared just before 6 p.m. Fire officials said one of the vehicles involved was exiting a highway too fast for the current weather conditions.

"Slow down and arrive alive," they wrote in a follow up social media post.
