With the Potomac River swollen by last week's heavy rain & having crested just above floodstage on Saturday, I went to Great Falls Park on Sunday for a look:
While the Potomac provided an amazing sight - the most powerful rapids I've ever seen that close up - the river remained far from the record. That takes a lot more than a few inches of rain. For example, the near-record flood of 1996 followed not just two feet of snow, but 60 degree temperatures accompanied by an inch of rain. All that combined to cause the Potomac at Great Falls to rise a mind-boggling 85 feet in just two days. Capital Weather Gang has the story & some incredible photos.
Today's river level couldn't touch that, but it was plenty to provide some interesting images:
