The storm has moved out of the Valley, and now the fog has rolled in.

KMPH News viewer Devo sent in this photo of the fog in the South Valley. It was taken just before 7:30 a.m. Monday in southeast Visalia.

CHP officers say that when the weather changes, commuters need to change their driving habits.

When driving in thick fog, officials offer these tips to stay safe:

-Turn off radio and cell phone
-Slow down
-Remember to drive with lights on low beam
-Roll down your window slightly and listen for traffic

The CHP says that as many as 500 fog-related car crashes occur each year in the Central Valley.

Officials say that if you are involved in a fog-related accident, the best thing you can do is pull as far off the road as possible, turn off the lights, and move away from the car.

The CHP says all lanes of Highway 99 from Herndon Avenue to south of Shaw Avenue are back open.

Caltrans was forced to close the fast lane of southbound 99 because of flooding in the construction zone.

At one point, traffic was backed up to Avenue 12 in Madera.

The CHP warns drivers that the fast lane may be closed again later this afternoon if the rain causes more flooding.
