Today’s heavy rain has turned Four Mile Run into a raging torrent of murky water.

A Columbia Pike resident posted videos of the overflowing stream on Twitter this afternoon (Friday). The video was taken near S. George Mason Drive.

No major flooding problems were reported during the daytime Friday in Arlington, though forecasters warn that more rain may cause additional problems tonight.

There have, however, been scattered weather-related issues reported. A number of traffic signals have started flashing or gone dark and, as of 6:30 p.m., 165 Dominion customers were without power.

On N. Troy Street near Rosslyn, between Key Blvd and Wilson Blvd, a large tree fell on cars and power lines, according to scanner reports.

Police closed a section of Washington Blvd in Virginia Square this morning after a U.S. Postal Service truck struck a utility pole.

Officers shut down the 3400 block of Washington Blvd between N. Kirkwood and N. Lincoln streets just after 11 a.m. Thursday.

The driver of the truck told police she turned left from N. Kirkwood Street onto Washington Blvd, but in the heavy rain and slippery conditions lost control of the vehicle and hit the pole.

No injuries were reported, there was reportedly no other traffic nearby and businesses nearby did not appear to lose power.

Crews from Dominion Virginia Power were on the scene to repair the pole and the power lines attached to it.


(Updated at 9:55 a.m.) It’s going to be a rainy day in Arlington and the D.C. area, with heavy rain and scattered storms likely.

The rain may cause some minor flooding problems on the roadways and along streams, forecasters say.

“Rain will be locally heavy at times through this evening,” said the National Weather Service. “Localized flooding of small streams and creeks as well as urban areas is possible late this morning into this evening.”

More from NWS:

At 907 AM EDT, radar indicated showers with isolated thunderstorms were located along a line extending from Ashburn to Aquia Creek. Movement was northeast at 40 mph.

Locally heavy rainfall can be expected.

Locations impacted include…
Arlington, Alexandria, Stafford, Columbia, Germantown, Centreville, Waldorf, Dale City, Rockville, Bethesda, Gaithersburg, Reston, Leesburg, Annandale, Clinton, Olney, Springfield, College Park, South Riding and Fort Washington.

Locally heavy rainfall is also occurring with these showers, and may cause ponding of water on roadways and cause small streams to go out of their banks. Be alert for the potential of standing water and hydroplaning.

The weather is already causing problems on the roads and at the airport:


(Updated at 9 a.m.) As feared, it was pouring rain during last night’s Clarendon Mardi Gras parade.

But the raindrops did not dampen the spirits of those in the parade, who made their way up Wilson Blvd to the delight of thin but enthusiastic crowds.

From a dancing monkey to a guy on a penny-farthing to a bunch of people pedaling on the Trolley Pub, the parade hearkened back to a bygone era when “Keep Clarendon Weird” was the neighborhood’s motto.


Hourly forecast for 2017 Clarendon Mardi Gras parade (via Weather.com)

(Updated at 5:45 p.m.) Organizers are hoping for a Mardi Gras miracle, but it looks like tonight’s parade in Clarendon will be a soggy one.

The 18th annual Clarendon-Courthouse Mardi Gras Parade is slated to kick off at 7 p.m., making its way up Wilson Boulevard from N. Barton Street to N. Irving Street.

2013 Clarendon Mardi Gras paradeAn hourly forecast suggests rain may begin shortly before the parade begins, but Matt Hussmann, executive director of the Clarendon Alliance, says it will go on rain or shine — unless there is lightning in the area.

“We’re going forward and hoping the weather holds off,” said Hussmann. “The Mardi Gras Ball will go on irrespective.”

The annual parade has not had the best luck with weather. It was postponed in 2010, postponed and then cancelled in 2014, and postponed again in 2015 — all due to snow. It rained during the rescheduled 2015 parade.
