Shut off gas service at the valve next to the meter and turn off the water service at the main valve. Do not try to cross a flowing steam where water is above your knees. Do not try to drive over a flooded road. You could be stranded and trapped. If your vehicle stalls, abandon it immediately and seek higher ground.
Many people drown while trying to rescue their cars.
Do not try to enter areas closed by local law enforcement agencies, the Sheriff or California Highway Patrol. Avoid unnecessary trips. Advise others of your destination. Use the telephone for emergency needs or to report dangerous conditions. Beware of downed power lines or broken gas lines.
