I wouldn't think so, because some of the important alerts are very time
sensitive.  It's been mentioned several times in this thread that the
earthquake alerts are on the order of 10 seconds in advance.  I know
someone that survived a tornado by a few seconds (the time it took to
get out of bed and get to the bedroom door as the tornado dropped the
second floor of the house on the bed).

4G/LTE/5G networks could be further leveraged for this. In Denton County,
TX, USA, you can register to "opt in" to receive weather alerts. We get
tornadoes here. I could see better leveraging of that technology than
streaming services. It is uncommon to find anyone without a cell phone in
the US anymore.

Yup; it's called Commercial Mobile Alerting Service (Or Wireless Emergency
Alerts, if you're a consumer), and it's been deployed, over SMS Cell Broadcast,
for about 10 years now, depending on your carrier.

NWS can actually send Tornado WARNINGS *to specific sectors of specific towers*,
so they can warn exactly the people necessary in real-time... if it's implemented
correctly along the entire path.  I'm not actually certain which carriers if any
have actually deployed the enchilada.
