“We are expecting several inches of rain today from the remnants of Hurricane Ida, picking up in intensity in the early afternoon until around midnight,” Fairfax County said in a post on its emergency information blog. “We have already experienced an early morning storm that has led to power outages, swift water rescues and numerous road closures due to downed trees and flooded roads.”

Road closures due to flooding and downed trees have been reported throughout the county, but as of 8:30 a.m., they have been particularly concentrated in the Reston District Station area, according to the Fairfax County Police Department:

Reston District Station

Browns Mill Rd and Pennycress Ln, closed due to down tree

Beach Mill Rd and Clubview Dr, closed due to downed tree

Hunter Mill Rd and Cedar Pond Dr, closed due to flooding

With more rain expected to fall today, the National Weather Service has extended a Flood Warning for northwestern Fairfax County until 11:30 a.m., citing Reston, Herndon, and Great Falls among the areas that could experience flooding.

“At 8:20 a.m. EDT, stream gauge reports indicated water levels continue to rise across the area. Flooding is ongoing,” the NWS said in its alert.

A Flash Flood Watch is also now in effect for much of the D.C. region, including Fairfax County. It is currently set to last through tomorrow (Thursday) morning:

* A round of heavy thunderstorms early this morning may result in localized flash flooding, especially in the Washington and Baltimore Metropolitan Areas. Additional thunderstorms with heavy rainfall are expected across the area this afternoon and evening. Rainfall amounts of 2 to 4 inches are expected, with localized amounts up to 6 inches possible.

* This amount of heavy rainfall will not only result in the potential for considerable flash flooding of creeks, small streams, and urban areas, but also the potential for river flooding on the main stem rivers.

The Fairfax County Fire and Rescue Department is urging people to avoid driving through flooded or closed roadways, noting that stalled and trapped cars put the driver, passengers, and first responders in unnecessary danger.

“By now, many drivers across Fairfax County know which roads traditionally flood,” the department wrote in a blog post. “FCFRD asks that if you need to be on the roadways today that you stay informed and plan alternate routes around flooded roadways. Our firefighters and paramedics do not want to meet you by (a preventable) ‘accident’!”

While just up to an inch of rain is projected to fall on average, the thunderstorms could bring heavy rainfall within a short period of time to localized areas, potentially leading streams and creeks to flood.

Here is the full NWS alert:

…FLASH FLOOD WATCH IN EFFECT FROM 1 PM EDT THIS AFTERNOON THROUGH
THIS EVENING…

The National Weather Service in Sterling Virginia has issued a

* Flash Flood Watch for portions of DC, central Maryland and northern Virginia, including the following areas: in DC, District of Columbia.

* Numerous showers and thunderstorms are expected this afternoon and evening. Average rainfall amounts are expected to be between one half to one inch. However, thunderstorms will be capable of
producing very heavy rainfall rates of 2 to 3 inches per hour, causing localized amounts of 2 to 4 inches possible. While storms are possible any time this afternoon through this evening, the most widespread thunderstorm activity is most likely to be late this afternoon through early this evening.

* Heavy rainfall amounts in a short period of time may result in rapid rises on streams and creeks as well as the potential for flash flooding in urban areas.

(Updated at 10:05 a.m.) An Areal Flood Warning is now in effect for Fairfax County.

Between one and two inches of rain had already fallen by the time the National Weather Service issued the alert at 7:18 a.m., with flooding expected to remain a risk until 1:15 p.m.

As of 9 a.m., the Fairfax County Police Department reported numerous road closures, including Hunter Mill Road at Hunter Mill Station due to flooding. A downed tree has necessitated a closure of 10100 block of Wendover Drive in Vienna.

While the heaviest rain and flooding has emerged in the Tysons/Vienna area, construction on Route 7 appears to have contributed to high waters near the Baron Cameron Road intersection in Reston.

Another driver reported around 8:05 a.m. that emergency responders had blocked off three lanes of the Dulles Toll Road, possibly around exit 14 at Hunter Mill Road, “due to severe flooding.”

The Fairfax County Fire and Rescue Department urged people to avoid driving if possible, particularly on roads that are known to be prone to flooding.

At 9:50 a.m., the fire department said that it had responded to three different calls for downed electrical wires and two calls for fallen trees just within the past 25 minutes.

“Assume all wires are power lines & LIVE!” FCFRD tweeted. “Avoid approaching/touching anything nearby. Be careful around downed trees as wires may be hidden in tree.”

Like much of the D.C. area, Fairfax County is now under a Severe Thunderstorm Watch that will be in place until 9 p.m.

The region is bracing for a second consecutive night of potentially damaging wind and rainfall after a storm that swept through late Wednesday (July 28) resulted in power outages that affected thousands of people in Fairfax County, particularly around McLean and Falls Church.

While many of the outages have been addressed, Dominion Energy’s outage map shows that, as of 3:30 p.m., crews are still working to restore electricity in some areas.

A Tornado Watch has been issued for D.C.’s Maryland suburbs, but Fairfax County could see damaging hail, isolated flash flooding, and large hail from the incoming storm, according to the National Weather Service.

The Fairfax County Office of Emergency Management advises residents to “stay weather aware and know what to do if a warning is issued,” which would mean that severe weather is imminent or underway.

The National Weather Service has issued a Flash Flood Watch for the D.C. region, including Fairfax County, that will take effect at noon today (Thursday).

Set to expire at midnight, the advisory warns of the potential for two to four inches of rain to fall within a short period of time:

* From Noon EDT today through this evening

* A cold front will drop southward into the area today. This front will become the focus for slow moving thunderstorms this afternoon and evening. Because of the slow motion and ample moisture in the atmosphere, storms may drop 2 to 4 inches of rain a short period of time, resulting in flash flooding.

* Heavy rainfall in a short amount of time can result in rapid rises of water in streams, creeks, and urban areas.

The Baltimore-Washington NWS says the Flash Flood Watch is primarily in effect for the the northern and central parts of the region, but flooding could occur almost anywhere, and the risk could extend to tomorrow (Friday).

“A Flash Flood Watch means that conditions may develop that lead to Flash Flooding. Flash Flooding is a very dangerous situation,” the NWS said. “You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.”

More than 5,000 people in northern Fairfax County are currently without power, as a thunderstorm pummels the D.C. area.

According to Dominion Energy’s outage map, the largest outages are concentrated north of Tysons and in the east Reston and Great Falls area, which is currently experiencing three separate outages in the wake of the storm that started pouring rain earlier this evening (Thursday).

A crew has been dispatched, but as of publication, there is no estimated time of restoration yet.

Another outage affecting 1,786 customers around Colvin Run and Lake Fairfax was also caused by a lost circuit with an estimated time of restoration pending investigation.

Finally, 687 people have lost power around Difficult Run Stream Valley Park. The cause and estimated time of restoration are both pending investigation.

In a Severe Thunderstorm Warning issued at 8:21 p.m., the National Weather Service advised residents to move indoors to the lowest part of their residence.

“Large hail and damaging winds and continuous cloud to ground lightning is occurring with these storms. Move indoors immediately,” the NWS said. “Lightning is one of nature’s leading killers. Remember, if you can hear thunder, you are close enough to be struck by lightning.”
