Weather and Shipping Deadline Extensions

[wilsonmw04]

Greetings folks,
I need some advice from the CD community. Please advise:

the situation:
Over the past 5 days, I have met with my team for 3 hours due to weather. We have had 12" of snow Saturday and sub freezing temps for the vast majority of time since. (Before the folks up north say, "12 inches of snow?!?!?! that's nothing." remember, this is the south and we don't have the equipment to deal with this like you do.) Those three hours happened today where I got a polite rebuke from my Principal for having students in the school when the school is closed. With more sleet and snow tonight and more on the way this weekend, I do not see schools opening until sometime next week. We are a small team that works out of my classroom at the school. I am concerned that we will miss over 7 days of build time because of school closings. I have put a bug in the ear of my Regional Director about my team's situation, but I would like some data before I make an official request for an extension.

The Questions:
What is the history of weather related shipping extensions for FRC? I've heard it has happened before. Is an extension given to individual teams or is an entire region given a blanket extension?
I have seen threads on CD in the 2005 season complaining about weather, how bad does it have to be to get a bit of relief?
