Trick-or-treaters last night might have noticed a chill in the air and the National Weather Service (NWS) has confirmed it’s likely to get colder tonight.

The NWS has issued a freeze warning from 11 p.m. this evening (Wednesday) to 10 a.m. tomorrow (Thursday). The source is a cold front pushing through the region with potentially hazardous driving conditions tonight.

According to the NWS:

…FREEZE WARNING IN EFFECT FROM 11 PM THIS EVENING TO 10 AM EDT
THURSDAY…

* WHAT…Sub-freezing temperatures as low as 25 expected.

* WHERE…Portions of central, northern, northeast, and southern
Maryland, The District of Columbia, central and northern
Virginia, and the eastern panhandle of West Virginia.

* WHEN…From 11 PM this evening to 10 AM EDT Thursday.

* IMPACTS…Frost and freeze conditions will kill crops, other
sensitive vegetation and possibly damage unprotected outdoor
plumbing.

NWS said locals should take steps to protect tender plants from the cold. Outdoor water pipes should be wrapped, drained or allowed to drip slowly to prevent freezing or possible bursting. Those with in-ground sprinkler systems should drain and cover above-ground pipes.

As for whether Alexandria will have a snowy winter season, experts were mixed earlier this year on the chances for snow, with the National Oceanic and Atmospheric Administration predicting higher than-average temperatures in Northern Virginia this winter but Washington Post predicting above-average snowfall.

At the risk of flooding readers with stormwater stories today, locals recovering from last night’s flooding should be aware there’s a chance for more tonight.

A flood watch is different from a flood warning, but it’s of particular note coming to quickly after the last storm.

The City of Alexandria said there could be up to two inches of rainfall with excessive runoff in flood-prone locations around town.

The flood watch, ironically, overlaps with the start of a meeting about putting more resources into a flood mitigation grant program.

If you’re looking for something to tide you over until the weather passes, Port City noted that it has cases of Derecho beer in stock — a throwback to an interesting bit of local stormy brewing history.

A storm has reached Alexandria, as seen on radar around 4 p.m. on Aug. 14, 2023

(Updated at 5:40 p.m.) The National Weather Service said the storm is no longer capable of creating a tornado, though flash flood warnings remain in effect.

The storm which prompted the warning has weakened below severe limits, and no longer appears capable of producing a tornado. Therefore, the warning has been cancelled. However gusty winds and heavy rain are still possible with this thunderstorm.

The National Weather Service issued tornado, severe thunderstorm and flash flood warnings for Alexandria earlier today.

Flooding has been reported at 1033 W. Glebe Road in Arlandria, according to scanner traffic.

The warnings have been issued for Alexandria and its surrounding localities.

An alert said a thunderstorm capable of producing a tornado was spotted over Franconia and moving northeast. Those in the area are advised to seek shelter.

This comes after another warning for tornadoes and floods was issued last week.

The full warning is below:

* TORNADO WARNING FOR…

SOUTH CENTRAL ARLINGTON COUNTY IN NORTHERN VIRGINIA…

EAST CENTRAL FAIRFAX COUNTY IN NORTHERN VIRGINIA…

THE CITY OF ALEXANDRIA IN NORTHERN VIRGINIA…

The National Weather Service has updated its earlier hazardous conditions with a new Tornado Watch.

The watch is in effect for many localities across Northern Virginia and as far down as the Richmond area. The watch and hazardous conditions come one week after another storm hit Alexandria and took out power to much of the city.

The Tornado Watch is in effect until 9 p.m.

Forecasters say the threats include “damaging and locally destructive hurricane-force winds, along with the potential for large hail and tornadoes, even strong tornadoes.”

Winds in excess of 74 miles per hour are possible.

…SEVERE WEATHER OUTBREAK EXPECTED OVER THE MID-ATLANTIC REGION BETWEEN 2 PM AND 10 PM TODAY, INCLUDING THE GREATER BALTIMORE/WASHINGTON METROPOLITAN AREAS…

An outbreak of severe storms is expected this afternoon and evening across the greater Baltimore/Washington region, with numerous severe thunderstorms expected. There is a significant threat for damaging and locally destructive hurricane-force winds, along with the potential for large hail and tornadoes, even strong tornadoes.

The timing of this outbreak varies with your location. West of the Blue Ridge Mountains, you can expect the storms to arrive between 12 Noon and 3 PM. East of the Blue Ridge Mountains, timing will be from 4 PM to 8 PM. The greater Baltimore/Washington Metropolitan Areas can expect the storms to arrive between 5 PM and 7 PM.

Now is the time to review your severe weather safety procedures for the possibility of dangerous weather today. Do not be outdoors when the storms arrive. When you hear thunder, go indoors to a sturdy building or structure. While seeking shelter indoors, go to the lowest floor to an interior room. Stay away from windows. Those in mobile homes or weaker structures should plan ahead of time to shelter in a stronger shelter. Be prepared for extended power outages, and the potential for some roads to be blocked by fallen trees.

For the after-event cleanup, do not go outside until 30 minutes after you hear the last thunder, otherwise you will be still susceptible to lightning strikes. Be aware of downed power lines and unstable branches and trees.

Stay tuned to NOAA Weather Radio, weather.gov, or other media for watches and warnings. If a Severe Thunderstorm Warning or Tornado Warning is issued for your area, move to a place of safety, ideally in an interior room on the lowest level of a sturdy building.

The National Weather Service (NWS) is warning that low-lying areas of Alexandria could see as much as two or three feet of tidal flooding for the next few days.

In a coastal flood warning, the NWS said from tonight (Thursday) at 8 p.m. until 2 p.m. on Saturday (Oct. 30), high tides could flood parts of the city — particularly along the waterfront.

“Water is expected to approach buildings near King Street and Union Street,” the warning said. “Shoreline inundation up to one foot above ground is possible elsewhere.”

The warning noted that tides could reach four feet above normal levels at high tide, which in Alexandria is at 2:30 a.m. and p.m.

“Take the necessary actions to protect flood-prone property,” the NWS said. “If travel is required, do not drive around barricades or through water of unknown depth.”
