Update 9:20 a.m.: The Post has its story up on the on-going rescues along River Road. They’ve made some calls:

Officials at the Washington Suburban Sanitary Commission could not immediate provide details of when and how the underground water pipe broke in the vicinity of River Road and Fenway Drive.

But the result — waves of water covering River Road for several blocks — left several cars trapped. Helicopters hovered over the scene, the whirring of their propellers adding to the stiff winds and blowing the already high waves over the sides of the trapped vehicles.

WJLA is reporting that MOCO police received a call for the water main break at 7:55 a.m. Those on the scene are estimating that the water is between four and five feet high. The station has this graph that should trouble people:

Washington Suburban Sanitary Commission confirms that this is a 66 inch water main break. They cannot get to the area to shut the water off right now and are trying to go further up the line to shut it off.
