Last night produced one of the most extensive thunderstorms I have ever
seen.
First flashes seen about 1800 on the way back from the Isle of Mull to
the Isle of Colonsay. Things hotted up around 1930 as we approached
Colonsay and very heavy rain came too.
A lightening strike caused a power blackout at about 2015 which lasted
after 2200while the storm continued. The centre of the storm then moved
off eastward towards Jura and continued until at least 0100 this morning
with flashes every few seconds giving splendid views of fork lightning,
sometimes several at a time.
As far as I could see the storm covered at least 20 miles at any one
time and was a most magnificent spectacle.
After 0100 I went to sleep but there was at least one more power cut
during the night.
