A portion of southern Arlington County is now under a Flood Warning, as a slow-moving storm drenches areas south of Route 50.
The warning is in effect until 8:45 p.m. An inch or so of rain has fallen and flooding is imminent, the National Weather Service says.
A Flash Flood Watch, meanwhile, remains in effect until 6 a.m.

EXCESSIVE RUNOFF FROM HEAVY RAINFALL WILL CAUSE FLOODING OF SMALL CREEKS AND STREAMS, URBAN AREAS, HIGHWAYS, STREETS AND UNDERPASSES AS WELL AS OTHER DRAINAGE AREAS AND LOW LYING SPOTS.
(Updated at 1:35 p.m.) After getting drenched by a storm early this morning, Arlington may be getting another round of heavy rain tonight.
The county and the D.C. region is currently under a Flash Flood Watch. Slow-moving storms are expected to form this afternoon, dumping torrential rainfall on ground already saturated by the morning storm and Isaias earlier this week — a recipe for flooding.
The watch is now in effect until 6 a.m. Friday; it was originally set to expire at midnight but was extended Thursday afternoon.
More from the National Weather Service:
…FLASH FLOOD WATCH IN EFFECT THROUGH THIS EVENING…
Through this evening… Numerous slow moving showers and thunderstorms continue to develop across the region and should expand and redevelop with time. Locations which are repetitively affected could receive multiple-inch rainfall totals. This could lead to rapid rises on streams and flash flooding of low lying areas.
PRECAUTIONARY/PREPAREDNESS ACTIONS… A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
The Flash Flood Watch was expanded to now include all of northern/central VA, the WV panhandle, and all of central/southern MD. It was also extended until 6 AM Friday morning. Heavy rain is expected to develop this afternoon into tonight and could lead to flash flooding. pic.twitter.com/t33klZNzLm

Isaias made landfall in North Carolina last night as a Category 1 hurricane and is now approaching the D.C. area as a tropical storm.
Wind from the storm is expected to ramp up locally over the next hour, but the main threat remains heavy rain.
The National Weather Service issued a Flood Warning this morning for Arlington, Alexandria, Falls Church and parts of Fairfax. Several additional inches of rain are likely to fall and cause flooding, forecasters say.

(Updated at 11:55 a.m.) Arlington County is urging residents to prepare today for Tropical Storm Isaias, which is currently making its way up the East Coast.
While windy conditions and some thunderstorms are likely as Isaias approaches this afternoon and evening, the main threat locally is heavy rain. Forecasters say the tropical storm could dump 3-6 inches of rain on the immediate D.C. area, potentially causing flooding.
A Flash Flood Watch is in effect for Arlington, D.C. and surrounding areas through Tuesday. A Tropical Storm Watch was upgraded to a Tropical Storm Warning late Monday morning.
The last time such a warning was issued for Arlington was for Hurricane Irene in 2011. That storm caused moderate damage around Arlington, mostly from felled trees.

Nearly one week after advocates flooded the County Board with concerns that planned stormwater investments in the Capital Improvement Plan favor Arlington’s wealthier neighborhoods, staff returned to the County Board to argue that the proposed investments were addressing important issues below the surface.
The renewed push for improving the County’s stormwater capacity is tied to historic flooding that took place last year and devastated many Arlington homes and businesses. County Manager Mark Schwartz has proposed a $50.8 million stormwater bond, among other bonds, to be sent to voters in the November election.
Some speakers at the earlier meeting criticized the bulk of that investment, $26.9 million, for going to the Spout Run watershed that runs through affluent communities around Lee Highway. The watershed was identified by county staff as a location with some of the highest concentration of recent flood damage to homes.
In a work session with the Arlington County Board yesterday (Thursday) Dept. of Environmental Services Director Greg Emanuel said the stormwater investment was based on the status of pipes below the surface and not the economics of the neighborhoods above.
“As you know, we’re trying to apply an equity lens on all our policy decisions,” Emanuel said. “[For] investments to infrastructure, unlike services with transit, we believe should be based on system-condition and need or identified deficiencies. We believe that should be regardless of demographics or geography, basically who is on the surface.”
Emanuel argued that, just as earlier investments had cut down on flooding around Four Mile Run in South Arlington, the proposed investments in northwest Arlington would provide lasting relief to residents struggling with flood issues. It would also benefit a wider swath of the county, he said.
“This decade, our proposed investments are predominately proposed for watersheds in the northwest part of the county based on modeling and actual experience,” Emanuel said. “It’s an interconnected system. Improvements such as detention in upper parts of a watershed will provide benefits to everyone in a system downstream of that, down to Four Mile Run.”
Speakers last week criticized the county for focusing on benefits to low-density neighborhoods, but Emanuel said the County’s modeling indicated that’s where the most severe flooding is.
Arlington is “investing the most where the most flooding is occurring, which is the northwest watersheds,” Emanuel said. “Of course, it’s not just there, we’re doing important things like dredging and important flood controls on the southern end near the mouth of Four Mile Run.”
Emanuel’s assertion that the northwest watershed was the most in need of stormwater investment went mostly unchallenged by the County Board.
County Board member Christian Dorsey questioned why areas like Alcova Heights, Douglas Park, and Aurora Highlands weren’t listed as priorities when data showed flooding calls from those areas. Emanuel said the calls from those areas — Douglas Park in particular — were mostly from sewage backups. While those could be caused by too much water from storms getting into the system, Emanuel said it still left those areas ranked at medium or low severity compared to other places.
Another round of severe storms packing torrential rainfall and strong winds is possible today.
The National Weather Service has issued both flash flood and severe thunderstorm watches for Arlington and parts of the D.C. region.
The Flash Flood Watch is in effect until 9 p.m., while the Severe Thunderstorm Watch is in effect until 11 p.m.
“Severe thunderstorms are possible this afternoon and evening with locally damaging winds and large hail being the primary threat,” the National Weather Service says. “There is also an isolated threat for flooding.”
