Hi Folks,
Evan Bookbinder, the creator and former owner of Interwarn closed the company back in 2012, then sold the company/software to someone. To date, no one knows who owns the software and runs the servers. It is for certain they aren't keeping it updated, offering no support, yet they are still selling the all of the software associated with Interwarn. I used to use Interwarn, but no longer because of the lack of support and the associated issues with the servers.
If one is looking for radar software, please check out
GRLevel3. It is awesome and Mike Gibson, the creator and owner of the software provides excellent support. For severe weather messaging via email, SMS, Twitter, Facebook, etc. check out
