High winds and rain combined to make things difficult for drivers along the I-5 heading through the Grapevine on Wednesday night.
Winds were so high that they caused a semi-truck to jack-knife on Wednesday afternoon, closing off one lane. The wind continued to be an issue into the evening.
"It's terrible," said Jesse Harris, a truck driver who was stopped to get gas. "That's why I'm fueling up because it's almost about to blow me over."
Harris also said that if trucks don't take it slow, they could get what he called "straight winds," which he says are capable of lifting up the front of the truck and tossing it off the road.
Rain also affected visibility. Drivers said that the rain combined with oil coming off the road made for a bad driving combination.
"We were going so slow because the rain was so heavy, it was just [about] being able to see," said Dave Daniel, who was towing his RV through Frazier Park.
A wind gust of 46 miles per hour was recorded at the peak of the Grapevine at 9:13 p.m.
