An awful lot of stormwater just fell on the Washington area. DC Water shared this 2011 video about what happens to a raindrop after it falls in a storm until it gets to a river.
Stormwater has to pass through the Combined Sewer Overflow system, which mixes water and sewage. That is, unless and until DC Water digs new tunnels for stormwater (and, unfortunately, has to spend a very large amount of money to do it).
Yesterday, a giant storm smashed into the mid-Atlantic. Virtually nothing else of note happened.
Metro will reopen at 2 pm today on a Sunday schedule, and will return to normal weekday service tomorrow. There is no timetable about when the New York subway will reopen after facing what its chairman calls the worst disaster in its 108-year history.
Finally, forecasters expect flooding in the Potomac over the next few days as all the water that fell yesterday makes its way downriver.
WMATA's planning department has started posting more graphs and charts of ridership data, like one today changes in ridership over 5 years. A few recent charts show how holiday ridership compares to regular weekdays, Saturdays, or Sundays.
On holidays like MLK Day and Presidents' Day, when most offices are closed, Metro runs a Saturday schedule. That seems sensible, because the ridership pattern across the day closely resembles the typical Saturday.
When the federal government is closed but most private companies still have work, like Columbus Day and Veterans' Day, Metro runs a Saturday schedule with extra peak service. Then, the ridership graph looks like a blend between the Saturday and typical weekday pattern:
On some of the holidays where virtually everyone is off and people generally travel, like Thanksgiving, Memorial Day and Labor Day, Metro runs on a Sunday schedule. The ridership pattern looks a lot like a typical Sunday as well, except Thanksgiving where it's even lower:
Even though the final numbers aren't in yet, we were able to get an exclusive look at the ridership chart for today, during Hurricane Sandy. Here it is:
