NOAA Weather Radio frequencies are in the 162 MHz band.  I have no idea
how well a cell-phone could pick that up, but even if they could, it's
going to be a power draw.  Also, there are 7 different channels, and the
phone would have to know which channel to tune for the local area.

For phones, it is much more practical to use the (already provided)
notifications from the cell network (which you can mostly opt out of as
well).
