Yahoo!:Gustav has glancing blow
A mandatory evacuation order and curfew remained in effect, and nearly 80,000 remained without power after the storm damaged transmission lines that snapped like rubber bands in the wind and knocked 35 substations out of service.

CNN:
"On the beach, it was blowing hard enough that you had to squat down to take a picture; it could pretty much throw you around," he said. Wise said he and his wife ignored mandatory evacuation orders for his area.

网上的一个解释
I would use compulsory when I am 【forcing】 someone to attend a meeting.
You have to go to the meeting.
注:和compulsion相关
I would use mandatory when I 【want】 everyone to attend a meeting.
Either you or your representative has to go to the meeting.
注:下令
I would use obligatory when I want to make someone feel they should attend the meeting out of loyalty.
This one is more of a conscience matter.

My opinion on their usage. I'm hoping others will reply with their opinions also.

并不是所有人都撤离了，如果是compulsory的话，那么【必须人人】(即：强制撤离)都撤离（就好像义务教育或必修课人人必须接受一样），这里个人认为用mandatory更恰当。
