FLHurricane.com: filming hurricanes

I realize this is out of left field, but I figure I would give it a go ahead as it has been bugging me a bit:

I recently purchased an XL2 kit, with the 20x lens.

I am finnaly getting a rain cover (yeah... that will help), so my shots can be a bit more dynamic now. Stupid gun mics only work clearly with winds under 40 mph. Anywho, I am a bit concerned about the lens. I know that visible air bubbles form within the lens itself when exposed to high elevations. I am assuming this is because of pressure. Would it be correct to postulate, then, that I would have a simular problem in the eye of a, say, 940mb hurricane? I am also wondering how the rapid nature of the pressure fall could affect this.

Are there any photographers here that have experienced problems in this regard?

To the mods: This isn't so much a hurricane question as a camera one, so if it gets deleted, I understand.

Thanks to all
