I meant to congratulate you some time ago on this. It is working really well. I've been using it to track a thunderstorm cell that has been perched over me for about the last hour. It has dumped 2-3 inches per hour - sometimes the rate is far higher. Lots of lightning and thunder - unusually frequent for this part of the world. Look for the mudslide/debris flow stories from this part of the country soon. Web page showing hourly rainfall.
