According to my maps, the nearest lightning is off the coast of Yorkshire and in the Bay of Biscay, so no risk hereabouts at present. I'll stay on 10m JT65 for now but keep an eye on the storm map, ready to disconnect things if the need should arise.
UPDATE 2204z: The lightning maps show storms coming in our general direction, but still some way off. They may miss us, but I shall disconnect everything just in case.
UPDATE 2212z: Everything is now off and disconnected, but I found the PC mains was not on so the PC went to sleep and had turned itseld and the WSJT-X software off! So the lack of Es may have been me, due to the PC not being on! Doh! Sometimes me thinks I have a very small brain. Anyway, assuming there is no storm risk tomorrow, I shall be on 10m JT65 at breakfast time.
