Tuesday's downpour of rain has led to overturned vehicles, spinouts, flooding, and road closures in San Luis Obispo and Santa Barbara counties.
Traffic incidents have been significantly higher from Templeton to Buellton due to Tuesday's rain, according to the California Highway Patrol.
"You're seeing a lot of collisions as a result of people simply not slowing down, a lot of solo-type vehicle spinouts, overturns. Another thing to be concerned with is potentially flooding," said Mike Poelking, California Highway Patrol Public Information Officer.
CHP says since Tuesday's rain was the first substantial rainfall in months, oil on the ground has caused slippery driving conditions.
The rain also caused road closures in the eastbound lanes of Highland Drive between Santa Rosa and California Blvd. near Cal Poly's campus and flooding on parts of Highway 1 in Oceano.
Cal Poly police reported Highland Drive was reopened as of 7:15 p.m.
CHP says drivers should be aware when driving on areas such as Highway 41 and the Cuesta Grade for potential rock slides from Tuesday's rain.
In Arroyo Grande, lightning struck a power pole in the 500 block of Mesa View Dr. PG&E reports 493 customers were left without power.
