blitzortung.org... "Fireworks for your Mac!" Of course, those detectors and their reporting hardware are rather expensive.
I also like the local radar display via Wunderground (as long as it lasts...), it's main problem is the built-in delay, but the forecast track and speed are a big help. Of course, it's not much help if one does not have the display available; driving, shopping, etc. I'm not sure how the one-wire system would help if it doesn't also have accurate direction info and that is mainly a product of the size and strength of the cumulonimbus(es) movement. As you know, the fact that lightening has been detected in one place is not very good at predicting where the next strike will occur. That's why I always added another ten miles to the SOP distances!
Looks like another project for our "in-house" electronics guru (and his Dad [
Reinhard])!
