This is turning into a June 2006-like event.  Absolutely massive.  Some Mclean PWSs topping 6" now.

You should be nearing 3 inches total now, no?

Thank goodness this cluster is moving a bit - I remember in June 2006 it would just keep training. 

The rates are crazy this morning.

I was checking out the crazy pictures on WTOP and they had this blurb at the end of the article :o

All eyes turn to the south next weekend, where forecast models are hinting at a possible tropical cyclone in the Gulf of Mexico.  Long-range forecasts are hardly a given, but any storm that does develop in the gulf will need to be monitored for weather impacts in the D.C. region early next week.

According to a tweet, Four Mile Run has risen nine feet in the past 30 minutes.

Insane.

6.3 inches at home now.

Wow!  I'm  in the Ballenger Creek area, just passed 5".  More than 4" of that fell between 5:45 and 7:30 this morning.

Finally back to a computer.

Almost got flooded out in an underpass on a 395 SB ramp, but somehow I swam the car through in the wake of an SUV. Going where it went. 

I got to the Harris Teeters in Shirlington, parked, went up to the fourth floor- and saw Four Mile Run over its banks and maybe 5-7 feet below a triple tree near that intersection.

USGS was registering it at 8460 cubic feet a second, higher than anything in the last 120 days by far. Gage height 15.06.  Accumulated precipitation almost 3 inches.

Cameron Run got to 13200 cubic feet a second, 15.61 feet (any fish on the Beltway?).

DCA appears to have reported 3.35 inches.

I'm surprised actually at how few posts there were last night . Majority of short range guidance showed the big total potential in some spots in central Md  and I remember before bed Hrrr was obviously way underdone esp western suburbs around 10 PM  or so. Pretty extreme ff event for some . Here in Eldersburg area. There was some minor stream flooding and water on roads but nothing major .At home ...probably about same

Humans are plain dumb.  I saw so many drive through swift water and have their vehicles get pushed sideways.  I understand there are times you have nowhere to go but these were choices they made instead of turning around.  Plain stupid.

Took me 2 hours to get home from Arlington to Ashburn.  Lewinsville road, McGarity, Old Dominion, Leesburg Pike all closed.

My street was a mini-river from curb to curb in upper NW. That's only happened a couple of times since I've lived here. One of last August's cloudbursts, June 2006, maybe one or two others I've forgot. And I'm nowhere near any stream or creek. 

Amazingly, only a little bit of water in the basement. When I went down there earlier, I was expecting to spend my morning dancing with the water vac. Fortunately, as another poster said, it didn't train like 6/06.
