Wet Weather Causes 4 Vehicle Collisions in Arcadia

The first storm of the season contributed to four vehicle collisions Wednesday morning in , the reported. The collisions resulted in only one minor injury. Lt. Paul Foley urged drivers to take extra precautions in the wet weather. 

Long periods of dry weather before rains in Southern California can make the roads especially slick and dangerous when the rain finally comes.

"We go so long without rain that oil accumulates on our roadways," Foley said. "We have a lot of spinouts, cars sliding into the back of one another, things like that."

The National Weather Service says the storm, expected to last through Thursday, could bring a half to 1 inch of rain in coastal and valley areas. However, rainfall could total up to 2 inches in isolated areas facing mountain slopes.

Periods of gusty winds will likely accompany the rainfall.

Highs are expected to reach the mid-60s Wednesday and Thursday, with lows in the upper 40s. Warmer weather should return Friday, for an expected high of 72 degrees. 

Meanwhile, motorists can avoid accidents by exercising patience, planning ahead for longer commute times and increasing their distance from other cars.

Also, don't forget one important rule.

"Whenever your windshield wipers are on, your headlights should be on," Foley said.
