Note that this is a widget. Once installed, you will have to add it to your homescreen, it won't do it automatically! You may need to reboot your phone before the widget shows as avalable (this is a known issue with Android).

Newschannel5 Storm Tracker radar watching app (Neither this app nor company are associated with Newschannel 5 in any way). Updates every 20 minutes unless refreshed manually.

A couple of my commenters don't seem to get the widget thing. Constructive comments would be appreciated (It's free, no ads after all)

It appears that at least one ad blocking application, Adaway blocks the site that provides the images. If you are not getting a display, consider disabling the ad blocking or add the site to the whitelist. The site is ftpcontent2.worldnow.com

Update, 2nd March. Images have not been updating since the 2nd of February. Looks like Newschannel5 definitely changed their site this time. Please stand by.
