Fire Weather and Evacuation

Wildfires are now more frequent, destructive, and fast-moving than ever. Berkeley residents must change how we prepare and respond.

Take control before a fire starts

Protect yourself and your family. Sign up for emergency notifications. Make a household fire weather plan. Be ready to leave the hills when the Berkeley Fire Department proclaims Extreme Fire Weather due to forecasted low humidity and high winds.

Stay informed

When fire threatens, information may change rapidly. Use these sources for the most up-to-date information from officials:

Zonehaven

Bookmark community.zonehaven.com on your computer and phone. Look up your evacuation zone now and write it down.

During a fire, emergency responders will use this portal to post real-time, zone-specific evacuation warnings and orders.

AC Alert

Sign up all your devices with AC Alert, the mass notification system for Berkeley and Alameda County.

For evacuation orders, evacuation warnings, and Extreme Fire Weather, we send AC Alert notifications over phone, text message, and email.

For Red Flag Warnings, we send notifications via email and text message. Download the Everbridge app to get push notifications for all AC Alert messages, including Red Flag Warnings.

1610 AM

We broadcast emergency information and instructions by radio on 1610 AM.

In an emergency, you can also monitor KQED 88.5 FM or KCBS 740 AM for updates.

Understand fire weather and warnings

Wildfire threat is closely tied to weather conditions. Officials will use the terms below to communicate current risk levels. Learn what they mean so you can take appropriate action to protect yourself.

For an in-depth explanation of these terms, watch our video about fire weather.

Red Flag Warning

The National Weather Service declares a “Red Flag Warning” when low humidity and high winds combine for elevated fire risk.

During a Red Flag Warning, keep your phone on and with you at all times, avoid any activities that could cause a spark, and be prepared to rapidly evacuate if necessary.

Extreme Fire Weather

The Berkeley Fire Department declares “Extreme Fire Weather”—a Berkeley-specific designation—when forecasted wind speeds and humidity levels during a Red Flag Warning would produce especially risky conditions in Berkeley.

Fires that spread under Extreme Fire Weather conditions can quickly become catastrophic.

The Berkeley Fire Department recommends that residents make plans to leave the hills during periods of Extreme Fire Weather.

Extreme Fire Weather is far more rare than Red Flag Warnings. In 2020, Berkeley had 25 days of Red Flag Warnings and only 2 days of Extreme Fire Weather. Yet this narrow range of weather conditions is when the most destructive fires happen.

The 1991 Oakland/Berkeley Hills fire, as well as most of California’s recent firestorms, ignited when conditions were within Berkeley’s “Extreme Fire Weather” thresholds.

Fire evacuation

In the event of a fire, we will send evacuation notifications over AC Alert. You will get different types of alerts based on the current threat level in your evacuation zone:

• Evacuation Warning: Sent to notify you of a known, active fire that potentially threatens your area.
  
  If you get an evacuation warning, get ready to evacuate on immediate notice. If you have children, pets, mobility issues, or any other factors that would make it hard to get out quickly on foot, you should leave when you get an evacuation warning.
  
  Note that in a fast-moving fire, there may not be time to issue a warning before an evacuation is ordered.
• Evacuation Order: Sent when there is an immediate life safety threat in your area, such as an active wildfire.
  
  These are lawful orders, and everyone must leave immediately when an Evacuation Order is issued.

Make a fire weather plan

Fires are unpredictable and conditions can change rapidly. Make a plan with your household ahead of time for what you will do during fire weather.

Identify your trigger for leaving the hills

Will you wait to evacuate after fire starts, or will you leave during periods of heightened threat?

If you live in Fire Zone 2 or 3 (the Berkeley hills),the Berkeley Fire Department recommends that you leave during Extreme Fire Weather, before a fire starts.

Leaving early gives you the most control over how you will get down the hill and what you can bring. If you leave after a fire starts, you may not be able to get out with your car, so you must be prepared to evacuate on foot.

Decide where you will go

Whether you plan to leave early or after a fire starts, think ahead of time about where you’ll stay. Talk to friends and family who you might be able to stay with, or consider putting aside money to stay in a hotel.

In an evacuation, we will set up mass care sites for those who have no place to go, but these will take time to set up and will rarely be your most comfortable option.

Identify evacuation routes

Choose at least two routes by foot and two routes by car. For driving routes, focus on main roads that connect with major streets and highways. Bigger roads will have more space during an evacuation.

If available, foot paths generally offer more direct walking routes downhill than City streets. Berkeley Path Wanderers sells a high quality, durable map that includes footpaths. Consider purchasing a copy for your go-bag and highlighting potential routes in advance.

For additional guidance, watch our video guide to making a household fire weather plan.

Be ready to evacuate

Leaving the hills during Extreme Fire Weather provides significant protection to you and your family. But it does not eliminate risk entirely. Fires can ignite and spread under normal conditions.

Berkeley residents, and hills residents especially, should always be ready to evacuate rapidly if needed:

• Have a go-bag
  In an evacuation, you may have only moments to leave. Everyone in your home needs a “go-bag” with the items you need to safely evacuate, including a flashlight, map marked with evacuation routes, a whistle to signal for help, cash, and copies of important documents.
  
  Make sure your go-bag is light enough to carry if you have to leave your vehicle and evacuate on foot. Use our wildfire evacuation checklist as a guide to pack your go-bag.
• Practice evacuating with your household
  Review your plan and practice your evacuation routes with your household. Carry your go-bag with you when you practice.
  
  Regular practice ensures everyone will know what to do in an emergency, when you must act quickly.
• Stay alert during fire weather
  
  Keep your phone on and with you at all times during a Red Flag Warning. Put go-bags by the door and back into your driveway so it will be easier to get out quickly.
  
  Review your evacuation zone and your evacuation plans with your household.

Download our evacuation checklist and keep it in a prominent place in your home.
