Note: Someone pointed out that the latest link for the new version of Radar In Motion was actually to an extremely old version! I have corrected this. So if you downloaded it from this post, try it again and it should work.
I finally found a little bit of time to fix Radar In Motion! As a result, I have released Radar In Motion 2.6.2. The version fixes weather alerts, which have apparently been broken for some time, and also fixes access to National Weather Service maps. Enjoy!
