Would You Dive In A Thunderstorm

In a recent Divemaster class there was a question about what would cause you to cancel a dive. Now the book had all sorts of reasons; weather, visability, water or air temperature, entry not safe and a few others. Well given out location most of those conditions would not warrant canceling a dive except for weather. Now the only weather I could think of that would make me call a dive would be a thunder or lighting storm. So here is my question to you.
If you had the oppertunity to dive Blue Lake and just before you hit the water the skies turned ugly and the a big thunder bumper was rolling on top of you. Would you cancel the dive?

I created a poll located at the bottom of the blog. Let’s see what you have to say.
