I was just watching WCVB and heard the MBTA will shut down service today at 2.pm because of Hurricane Sandy.
All #MBTA service will be suspended effective 2pm today.Customers are encouraged to make final #MBTA trips as early as possible.

It makes some sense. You have orange, red, and blue lines with underground power that is exposed. Add water to the mixture, and it could become fatal.
