Since there is no single technology that you can not be "Out of range of" I recommend a multi-faceted approach
The weather radio is a good one.. Epically if your radio is battery operated and has an EXTERNAL antenna connection.. And you have an external antenna.. I have a pocket unit and often my other VHF radios pick up NOAA clearly when it does not.
Next is weather apps for your smart phone... Go to the app/play store and search on NOAA.. NOTE M-Ping (A NOAA app) is so you can tell NOAA about bad weather.. They have Radar apps.. ALert apps and more.. My phone sounds like Big a symphony of ring tones when bad weather threatens.
