Whats wrong with "mini tornadoes" ?,I think 99% of those so described fit
nicely into that category.
Piddling little typhoons which blow a few tiles off and upset a couple of
caravans ,(unless they are yours of course ).
Q And why I am at it,why are showers with thunder and lightning always
described as "thunderstorms" ?,
whats wrong with thundershowers ,yeah I know sometimes its only lightning
seen ,
Perhaps the English language is not descriptive enough, still it winkles out
the more pedantic among us .........
