FRESNO, Calif. (KSEE/KGPE) – California Highway Patrol officials are asking drivers to stay home if they are able due to thick fog and low visibility along Highway 99 and throughout Fresno County.

A spokesperson for the CHP, Mike Salas, said officers have responded to 10 separate crashes along both the north and southbound sides of Highway 99 and throughout the county.

“It’s just been one of those days where it’s a combination of speed and fog. It’s definitely a huge factor when it comes to crashes,” said Salas. “We’ve had more than a dozen calls, multiple vehicle collisions in different areas. It’s just a reminder that when there is fog, always reduce that speed and buckle up.”

Authorities say officers are currently en route to the fatal crash near Shaw and Howard avenues. Stay with yourcentralvalley.com for updates.
