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.
