As I recall Katrina never got to that level. s it higher than a category
5?


Cheers, Alastair.


No; "M" is "major hurricane", ie cat. 3 (110mph) or above. It's mentioned
in the key at the top right of the chart. I think it is new, though; IIRC
the charts just used "H" up until this year.

Bewdley, Worcs. ~90m asl.


Ah! Thanks.

That would explain why Katrina at 4/5 was not an M.

Cheers, Alastair.
