AP-Officials say several early season storms have pushed California's snowpack _ which supplies much of the state's water _ to well above normal levels.

The state Department of Water Resources said Wednesday that early electronic readings indicate that the water content of California's snowpack is 146 percent above normal for this time of year.

The snowpack usually provides a third of the water used by households, farms and industries across the state. The department says the early storms have also replenished many of the state's reservoirs. Among those showing increases for this time of year include Lake Oroville in Butte County at 111 percent above normal, and Shasta Lake north of Redding at 113 percent.

The DWR will conduct its first official snow survey next week.

The California Department of Motor Vehicles would like to remind everyone to use low beam headlights when driving in the fog.

Officials say you should not use high beam headlights because they can reflect back and cause glare.

The CHP offers these tips to help you stay safe on the road:

• Turn off radio and cell phone
• Slow down
• Roll down your window and listen for traffic

Officials say 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 keep your foot off the brake pedal.

LOS ANGELES (AP) - The heat has yet to break, but Californians are being urged to turn down their air conditioners.

Operators of the state's electricity grid have declared a Flex Alert for Tuesday, telling customers to curb their power use as California's inland regions face yet another day of sky-high heat.

The California Independent System Operator says conservation will be critical with peak demand forecast at 47,500 megawatts.

Customers are being asked to set their air conditioners to 78 degrees or higher, to wait until after 7 p.m. to use major appliances and to turn off anything that isn't necessary.

A similar alert was issued for Friday.

The National Weather Service has issued excessive-heat warnings from Santa Barbara County through southeastern California and in much of the San Joaquin Valley.
