When clocks need to be moved forward one hour, Bay Area public safety officials are urging residents to also take the time to prepare for an emergency.
While changing the time on clocks, safety officials remind residents to change batteries in smoke alarms and carbon monoxide detectors and to check on emergency supplies.
The Monterey County Health Department advises that residents check that homes have a three-day supply of bottled water, non-perishable food and medication.
Those with pets should make sure supplies are prepared for them as well.
