Default The good old days.

Going through the Tropical cyclone records I noticed that the MetO has
this to say about Ketrina:

Katrina 12L NAT 23 August 30 August 150 -

That is active in the North Atlantic Basin between 23rd to 30th
August. No 10-minute MSW

That is there is no given quantity for the maxcimum sustained wind
speed (in knots) averaged over 10 minutes.

Anyone know why?
