Most useful post @gardengirlcanada, thank you.

Alas we have no mobile signal here in our part of rural west Wales, so please don't text me if you ever need a quick reply ;-)

We are still struggling to get anything beyond 2MB broadband so I'm guessing a good mobile signal here is still some way down the road (about 5 miles at present).

One weather related site I use on the web a lot to warn us of incoming lightning is https://www.lightningmaps.org - I don't know if there is an app version of this yet.
