Looks like it's really tightened up in the SE now - quite dramatic-
looking on radar. Due to pass here on the 18th floor in central London
in about 5 minutes or so. Could be - erm - interesting?!

Was *very* interesting as it passed here. Torrential rain
for about two minutes, reducing visibility to less than half a mile,
gusts of about Force 8 and a temperature drop of 3 deg that appeared
on my thermograph trace as "instant".
