When we have a storm here in the UK, BBC and ITV just report it on the main news and that is it.
I know a lot of this coverage can seem a little excitable, but the whole "us Brits are far more restrained" is not especially true.
Charlie Brooker picked up on it years ago.
The OP has listed news channels giving continuous coverage. When we had heavy snow back in February/March, it dominated all the news channels and main news bulletins here for days, including preparedness and weather warnings in advance.
Fine, we don't tend to go for the flashy graphics quite so much, but a hurricane is obviously worse than "a storm", and people would expect it to be on news channels. People evacuating from homes (even during hurricane season) is still newsworthy.
I was going to bring that up and it got coverage on World News, that and a rivers flooding (I think it’s the past year but no home or property was lost).
Except for the bits where they trail the local radio stations and frequencies in full just in case you lose pictures or go to your shelter.
They also promote heavily their app and live streams encouraging you to have extra USB batteries and ABC always be charging. Comcast also routinely opens their xfinitywifi hotspots* that are normally reserved for their customers to all.
As someone else said here and elsewhere broadcast stations have an obligation (which is why a many radio stations simulcast) to covey information about life threatening situations. If they don’t convey warnings they could get fined by the FCC. If it’s not a news producing station they have to air crawls and direct people to other sources. The cable channels don’t have that mandate. However when it’s going to hit / impact a large population area is when they usually go into “storm mode”. In other situations they may send one or two reporters.
*When Comcast’s supplies a customer a cable modem and router by default an a xfinitywifi (and cablewifi there’s agreement with other cable companies (Cox and TWC Spectrum) to allow each other customers to access hotspots)) hotspot signs on as well as the users private hotspot. Somehow they keep WiFi and DOCSIS traffic completely seperate. I heard that they have two WiFi routers built in to their modems. It’s come in handy for me several times the first block of homes that is served by one outdoor distribution box went up I was able to be connected to a neighbors. I also did the same on vacation as my hotels WiFi was spotty. And when your in a doctors office and all they air is HGTV (almost every doctors office has HGTV on and there’s only so much Love it or List It I can take

) and you want to listen to news without eating your data. On your phone it’s simple you download an app, it registers and stores settings for the variety of hotspots names, those that are safe and the login credentials.
