Safety directory
California local emergency alert systems
Local alert systems carry evacuation, severe-weather, public-safety, and other urgent notices according to the jurisdiction and incident. County and city systems can both matter. This directory contains 5 verified direct links.
Starting point
Keep more than one official warning path.
Use the city alert signup when a verified direct door is listed, and keep the county emergency-alert system for the address close by as well.
What changes the answer: Alert signup does not replace 911, an evacuation order, direct instructions from responders, or current fire, smoke, road, weather, and utility sources.
Verified direct links
Open the official local page.
Each row keeps the California Porch place page beside the official municipal service link.

When a direct link is not listed
Use the place page to find the right local office.
The direct-link list is intentionally narrower than California's city and town directory. Each incorporated place page still keeps the official municipal homepage, county page, and task-specific practical guide together.
About these links
Municipal links and source records
Reviewed 2026-09-15
The state roster establishes the incorporated city and town list. Every direct link on this page keeps its source file and source label in the generated municipal registry.
Use the official city or town homepage on the matching place page if a direct service URL has moved or the address falls outside municipal limits.
