From around 15:00 through to 21:00 yesterday, we had a bit of a storm.
I recorded 60mm of rain came down during the course of it and several
properties were flooded at the lower extremes of the village.

What was really weird, was the noise from the thunder. Aside from the
usual crashes, there was a continuous noise, which sounded rather like
a jet engine roar, which lasted for tens of minutes at a time. I have
never heard the likes of it before and just wondered what mechanism
would allow the noise from the thunder to continue for such a long time
and such a steady noise?

It sounded so unlike thunder, I went out several times, to see if it
might be wind noise or some other locally generated noise. It wasn't
because several others reported the same noise, in the path of the same
storm.
