San Luis Obispo County Evacuation Terminology

Becoming familiar with terminology before disaster strikes will allow you to quickly take action upon direction from local officials. Emergency officials will decide whether to evacuate or shelter in place areas based on the nature of the emergency. You will be told what to do over local radio and television stations. Remember, preparing for emergencies in advance is the best way to help protect yourself and your family.

Note* Depending on the emergency, there may not be time to issue an Evacuation Warning.  If you receive an Evacuation Warning, gather your family, pets and emergency supplies and be prepared to leave.  For those who know they would be unable to evacuate quickly, consider leaving when a Evacuation Warning is issued.  If you know you need assistance evacuating, don't wait until an Evacuation Order is issued, ask now.
