What to pack in an evacuation bag
Prepare essential items in a "go bag," such as a backpack and keep a sturdy pair of shoes and a flashlight by your home bed in case of a sudden nighttime evacuation, according to Cal Fire.

For your "go bag," Cal Fire recommends essentials such as:

Face masks or coverings
A three-day supply of non-perishable food
Three gallons of bottled water per person
A map marked with at least two evacuation routes
Basic first-aid and medical supplies
Sanitation supplies
Prescriptions or special medications
A change of clothing, including a long-sleeved cotton shirt and pants
Spare eyeglasses or contact lenses, if needed
An extra set of car keys, a phone charger
Cash, credit cards, or traveler's checks
A flashlight
A battery-powered radio with extra batteries
Copies of important documents, such as birth certificates, passports, insurance, a list of emergency contacts and phone numbers, etc.
Food, water, and medications for pets, if needed (The LA County has a checklist to consider for pets.)
A can opener

Cal Fire also recommends considering taking additional items, if there is more time available. These include:

Valuable items that can be easily carried
Family photos and other irreplaceable items
Personal computer information on hard drives and disks
Extra cell phone chargers, laptops, etc.
Depending on other natural disasters, the Red Cross also recommends considering packing other items:

A whistle
Matches
Rain gear
Towels
Work gloves
Tools/supplies for securing your home
Plastic sheeting
Duct tape
Scissors
Household liquid bleach
Entertainment items
Blankets or sleeping bags
