In the end Hanna hit the D.C. Metro area as nothing more than a big thunderstorm. Persistent rain, and occaisional gusts made it a good day to stay inside. At 8pm I decided to go and see how flooded Pohick Creek was. So with tripod and camera I clambered down the muddy slope through the woods to the waters edge.
The water looks like silk because in the rapidly fading light I had to use a long exposure of 30 seconds with an aperature of F5.6 focused at infinity. The river is considerably wider than usual, and is still 2-3feet above normal levels in this photograph. The debris and damage showed it had been a couple of feet higher still at the height of the storm.
Hope everybody else stayed dry and safe.
