Hi Chris,
Indeed, I can confirm Storm Blue has been deleted. I have an Octavia in Storm Blue on order (since 01 March) and the dealer phoned last week to spill the bad news that the factory (or Skoda) has deleted this colour and they will only honour this colour if the car had a build date, which mine did not. So I email Mr. Hazelwood (Skoda UK MD) and complained. His Executive office phoned back very quickly confiring the bad news. They had even spoken to the factory to try and push mine through, but they (the factory) was having none of it. A new blue, darker than storm blue will be available to order from week 26 (June). I have no idea why there is such a big gap between deleting one colour and replacing it with another.
