As of 2:00 am the power was out and I'm on battery backup now. I may ride my bike and see the normal flooding at Union & King Street in Old Town and check on some friends.
The power grid in our country is a failure and Pepco has asked the Canadians Power Company Teams to come down and help. I'm going to make my home kinda of "power grid free" somehow with more batteries, solar and a generator package.
Good luck to those who have been hit harder but over all the experience was like a typical summer storm.
The lower Potomac's troubles probably aren't over. I'm near the headwaters. The river and all tributaries are very high, although actual flood damage seems pretty minor here.
The problem is that all parts of the system from here to the Bay got dumped in last night, and as of this morning the lower Potomac was flowing backwards because the Bay, already high, was rising again with the tide. A cousin of mine on the Bay shore (Pasadena, MD) was stuck on the second floor with furniture floating on the first as of this AM.
What happens in this kind of situation is the whole drainage basin becomes one big traffic backup, with the maximum flood surge taking 2-3 days to reach the DC area.
So there's probably more to come.
