If you're just looking for alerts and warnings, your cell phone should suffice:
Receiving Alerts Away from Home
Wireless Emergency Alerts are not subscription based and there is no need to provide personal information to be able to receive a WEA. WEAs are based on location. You will receive a WEA message, even if you are:
In an area where you don't live
Outside the area where your phone is registered
If you travel into an area after a WEA was sent your WEA-capable device will receive the message, if the alert is still active.

I use Sense V2 Flip Clock & Weather
If you want something else, well .....
Personally, I don't see much need for NWS radio any more.
