The Integrated Public Alert & Warning System (IPAWS) is FEMA’s national system for local alerting that provides authenticated emergency and life-saving information to the public through mobile phones using Wireless Emergency Alerts, to radio and television via the Emergency Alert System, and on the National Oceanic and Atmospheric Administration’s Weather Radio via Non-Weather Emergency Messages (FEMA.gov, 2022).
Sacramento Alert (SacAlert) is a mass notification system used by Sacramento, Yolo and Placer Counties as well as participating cities within each county to disseminate messages to residents and business pertaining to the health, safety or welfare of a community affected by a perceived, imminent, or actual emergency. SacAlert has the capacity to send thousands of messages within minutes via phone, push notification, email, TTY and text. The system contains residential and commercial landline phone numbers of Sacramento County’s entire population. In accordance with the California Public Utilities Commission (CPUC), landline numbers were acquired from AT&T and Verizon’s 911 telephone database. Residents are also encouraged to sign up at sacramento-alert.org and enter additional phone numbers, email addresses and physical addresses as well as subscribe to non-emergency notifications (severe weather, community messages, safety alerts, etc.).
