Arlington — and much of the D.C. region — is now officially under a Winter Storm Watch.

The watch was issued just before 3 p.m. Forecasters are calling for up to 5 inches of accumulating snow, but 1-3 inches is most likely, according to the National Weather Service.

Gusty winds will accompany the storm and, paired with the snowfall, could fell tree branches and cause another bout of power outages.

Ahead of the storm, which is expected to have more severe impacts west of the D.C. area, Virginia Gov. Ralph Northam today declared a state of emergency.

“We expect this storm to have a significant impact in many parts of Virginia,” Northam said in a statement. “Declaring a state of emergency now allows our emergency responders to prepare, and to move supplies and equipment where they expect to need them the most. This also gives Governor-elect Youngkin the ability to respond to any storm needs swiftly. I urge Virginians to take this storm seriously and make preparations now.”

Arlington County and VDOT crews, meanwhile, have been pre-treating roads in advance of the winter weather, which is expected to start as snow Saturday afternoon before transitioning to sleet, freezing rain and then plain rain.

Heavy snow with up to 3-6 inches of accumulation is possible Monday, starting late tonight, according to the National Weather Service, which issued a Winter Storm Watch for Arlington County and other parts of the region early this morning.

Flash Flood Watch Issued Ahead of Arrival of Ida’s Remnants

By ARLnow.com
Expected track of the remnants of Hurricane Ida (via National Weather Service)

(Updated at noon) The remnants of Hurricane Ida are heading our way, and forecasters are already warning of potential flooding.

Ida has ravaged portions of Louisiana and Mississippi since making landfall as a Category 4 storm Sunday afternoon. It knocked out power to more than a million homes and businesses, including the entire city of New Orleans; interrupted 911 service; and caused catastrophic flooding, prompting numerous water rescues.

Now a tropical storm, Ida is on a northeasterly track that is expected to put its remnants squarely over the D.C. area starting Wednesday.

Two days ahead of Ida’s arrival, the National Weather Service this morning issued a Flash Flood Watch, to take effect from 11 a.m. Wednesday to 8 a.m. Thursday. Some 2-5 inches of rain could fall during that time.

Forecasters are also warning of the potential for severe weather or even tornadoes spawned by Ida.

“Heavy tropical rainfall could result in considerable flash flooding,” NWS wrote. “A few severe thunderstorms are possible Wednesday into Wednesday night. Damaging wind gusts and a brief tornado are the main threats.”

More from NWS:

…FLASH FLOOD WATCH IN EFFECT FROM WEDNESDAY MORNING THROUGH THURSDAY MORNING…

The National Weather Service in Sterling Virginia has issued a

* Flash Flood Watch for portions of DC, Maryland and Virginia…

* From Wednesday morning through Thursday morning.

* The remnants of Ida will interact with a stalled front, resulting in a prolonged period of heavy rainfall beginning Wednesday morning and continuing through Wednesday night. 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.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.

Strong storms are also possible tonight (Monday), with the arrival of a cold front that will end our stretch of sweltering weather and temperatures in the 90s.

“Isolated damaging wind gusts are possible this afternoon and evening,” NWS wrote. “An isolated instance of flooding is also possible.”

Just before noon, a Flash Flood Watch was issued for Monday afternoon.

Arlington Under Flash Flood Watch This Afternoon

By ARLnow.com

Get ready for another stormy afternoon — and possible flooding.

The National Weather Service has issued a Flash Flood Watch for Arlington and the immediate D.C. region. The watch, which takes effect at 1 p.m., cautions that heavy rain which can cause dangerous, rapid flooding is expected this afternoon and evening.

Yesterday’s afternoon thunderstorm toppled trees around Arlington and knocked out power to several thousand homes and businesses. No significant flooding was reported locally, but the storm left the ground waterlogged and thus increased the chances of flooding today.

More from NWS:

* 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.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.

JUST IN: Arlington Under Tornado Watch Today

Tornado Watch area (via National Weather Service)

(Updated at noon) The remnants of Tropical Storm Fred may cause more than just heavy rain today.

Arlington and most of the D.C. area is now under a Tornado Watch. The watch is in effect until 8 p.m.

The area is also under a Flash Flood Watch through 10 p.m. tonight.

Forecasters say conditions are favorable for the formation of tornadoes, though any such storms should be isolated. Severe thunderstorms are also possible.

Arlington is no stranger to tornados, though twisters are a relatively uncommon occurrence.

Last month an EF-1 tornado caused damage across several neighborhoods near Lee Highway. In April 2017, an EF-0 tornado chopped trees in half at Army Navy Country Club and caused some damage at the Macy’s in Pentagon City. Before that, a long-lived EF-1 twister struck Arlington, Alexandria, Fairfax County and D.C. in 2001.

More from the National Weather Service:

A FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH 10 PM FOR AREAS ALONG THE INTERSTATE 95 CORRIDOR. ISOLATED INSTANCES OF FLASH FLOODING ARE POSSIBLE AS TROPICAL MOISTURE OVERSPREADS THE REGION.

A TORNADO WATCH IS IN EFFECT UNTIL 8 PM. ISOLATED TORNADOES AND DAMAGING THUNDERSTORM WIND GUSTS ARE THE THREATS.

Fred Prompts Flash Flood Watch in Arlington

By ARLnow.com

The remnants of Tropical Storm Fred are making their way north, bringing the possibility of flash floods in the D.C. area.

Now a tropical depression after landfall in the Florida Panhandle, the bulk of the storm is expected to stay west of the metro area, tracking over West Virginia. But Arlington and surrounding areas are still expected to get soaked by heavy rains caused by Fred.

The National Weather Service this evening issued a Flash Flood Watch for the area, starting at 8 p.m. tonight (Tuesday) and extending to 10 p.m. Wednesday.

More from NWS:

The Flash Flood Watch continues…
