You basically have to decode the nixles or go to the local IOS.
All that said, Newsome is worse than worthless and a corrupt scum. Liberal policies and spending on every social justice cause and illegals vs taking care of the damn infrastructure. How can anyone be surprised at the mess?

The nixle messages for the past decade have been very clear and definitive re hunker down, get out Dodge or drop everything and run. Or the cops need help and are chasing bad guys in X area. Stay out of X area.
The nixles, during this bs are basically warnings but no specifics re high danger areas or need to evacuate. Now I have to go the local Office of Emergency Services (OES) site to try and see what is happening. Even, then we may have to wait 8 hours or so to see what is/might be happening.
We ran into this with Covid 19 warnings.
