Forecasters say Arlington could break its rainless streak next week, depending on what happens with Tropical Depression 16, which is expected to turn into Tropical Storm Nate.
The storm has the potential to intensify rapidly and could strike the Gulf Coast as a strong tropical storm or Category 1 hurricane this weekend. The storm is expected to make its way north just as a cold front is pushing into the East Coast.

The rain could arrive in Arlington by late Sunday night, but timing depends on how quickly the front moves through and its clash with the depression. That also would affect how much rain falls, but the Capital Weather Gang predicts it could be several inches.
The National Hurricane Center predicts that this storm will bring “torrential rain” to Central America, but cautions that it’s too early to determine any further impacts this early.

There’s been a lot of clean-up in Arlington following last Thursday’s strong storms that produced a weak tornado.
The National Weather Service says the tornado formed adjacent to the Army Navy Country Club and lasted for six minutes on its 4.5 mile journey through Pentagon City and into Washington, D.C. The F-0 tornado had peak winds of 60-70 miles per hour.
The Army Navy Country Club property experienced quite a bit of damage, and a spokesperson issued the following statement to ARLnow on Monday:
“The tornado did interrupt some of the Club’s golf operations, as we had to close 18 of the 27 holes of golf in the Club’s Arlington location. Due to the tornado, we lost dozens of trees, several water coolers, trash cans, and benches on the course. We are fortunate that the path of the tornado did not cause any injuries or damages to the buildings.”
The last time a tornado was recorded in Arlington was on September 24, 2001, when an F-1 that originated in Fairfax County traveled northeast for 15 miles through Alexandria and Arlington, then it crossed the 14th Street Bridge into the District. It caused extensive damage and injured two people in south Arlington.
The scene was different for Thursday’s tornado in Arlington and the two others confirmed in the region that day, said Chris Strong, a warning coordination meteorologist with NWS Baltimore/Washington. Not only were the tornadoes weaker, but they also formed in a different manner.
“These weaker ones last week were basically eddies along a gust front, rather than more classic supercell thunderstorm tornadoes,” Strong says. “Those eddies produced small whirls of wind that in narrow corridors snapped some trees and caused siding and roofing damages.”
Some of that damage occurred when a portion of the facade and roof of the Macy’s at the Pentagon City mall ripped off and fell onto a car, resulting in one minor injury.
Technological advances have prompted changes in how local emergency managers warn the public about tornadoes and other weather emergencies. Some parts of the country, especially those that are more prone to tornadoes, use sirens as a warning. But sirens aren’t necessarily as effective in Arlington and the District, partially because of the dense buildings and foliage.
“Tornado sirens are not used much in this region of the country,” Strong said. “One of the reasons they work better in tornado alley is the wide open spaces with lack of trees that allows the sound to travel well.”
The county has begun “phase three” of its snow removal process, during which workers will clear snow-covered neighborhood streets. Crews may take until Tuesday night to reach every street, the county said.
Though some major roads remain treacherous due to patches of ice, most traffic across the area appeared to be light or moderate with no major backups or road closures reported as of 8 a.m. this morning.
We appreciate your patience- we're making progress! This is a huge operation & it may take until Tues night to reach all the streets. #ARLwx

Want to know which streets are clear? Arlington’s snow plow map keeps track of where road crews have and haven’t been. And starting at noon today, residents can use the county’s snow reporting form to “identify snow issues that need attention.” Residents can also report issues by calling the streets hotline at 703-228-6485.
Most roads throughout the region are currently buried in snow and ice as snowflakes continue to fall.
Residents are being strongly urged by Virginia’s Department of Transportation (VDOT) to stay off the road unless absolutely necessary, but it seems like many across the area are heeding that advice.
Normally busy streets across Arlington have been virtually devoid of cars all morning. Though some people have ventured out into the snow and ice — two drivers were spotted struggling to climb a hill on Wilson Boulevard in Rosslyn earlier this morning — many appear to have stayed home.
Those that do drive, expectedly, are running into trouble. According to scanner traffic, a few cars have gotten struck on treacherous roads throughout the area, including one emergency vehicle.
More than a foot of snow has already fallen across the Arlington area, according to the National Weather Service. And it’s only going to get worse.
Wind gusts of up to 50 miles per hour, whiteout conditions and up to another foot of snowfall are possible through late tonight, says the Capital Weather Gang.
According to the Virginia Department of Transportation (VDOT), most roads throughout the area are in “moderate to severe” condition, meaning that a layer of snow or ice partially or fully covers the roadway. VDOT added that workers in Northern Virginia will attempt to clear interstates, high-volume roads and subdivisions throughout the day.
Residents are being strongly urged to stay off the roads unless absolutely necessary. Most seem to be heeding the advice, as traffic is nearly nonexistent even on normally busy roads in Ballston. Still, some people are making a go of it, despite VDOT’s advice. A pair of drivers were observed struggling to climb a hill on Wilson Boulevard in Rosslyn around 7:30 a.m. this morning.
Though the snowy conditions thwarted drivers across the area, Dominion has not reported any widespread power outages throughout the area since the blizzard began.

A sure sign autumn has arrived is the number of squirrels scampering around the county collecting nuts. But residents in many parts of Arlington will notice a lot less squirrel scampering than in years past.
It appears most parts of the county have fewer squirrels this year. Arlington County Natural Resources Manager Alonso Abugattas confirms that from spring through October — although no hard numbers yet are available — there have been “reports of fewer squirrels and anecdotal evidence” of a smaller population.
Abugattas said although many people immediately point to last year’s cold winter as the culprit, that’s probably not directly the cause. He said it would be very unlikely for large numbers of squirrels to die here by freezing to death.
“These animals, squirrels and so forth, if they have an adequate food supply, their little motors can keep them going and they can survive. If they have food they can keep their metabolism up and the cold won’t affect them as much,” he said. “Remember, we have squirrels way up in Canada, so they’re used to that weather. These animals are remarkably resilient.”
A more likely scenario, according to Abugattas, is that last year’s small acorn crop negatively affected the squirrel population. Many squirrels probably struggled to find adequate food with the decrease in acorns, but the problem is very localized. Certain neighborhoods where the animals managed to find other sources of food — such as bird feeders or berries — didn’t see the sharp decline other neighborhoods experienced.
“Places where they’ve been able to find an alternate food source, those may have been able to bounce back. It really depends on local conditions at that site. I still don’t think there are many places where there are extra squirrels, which we saw a few years ago,” said Abugattas.
Because it is the beginning of the season, so far the robustness of the 2014 acorn crop is not known. Researchers have begun analyzing acorn production but won’t have a better idea of the crop specifics for another couple of months. It’s something naturalists are paying close attention to due to the amount of wildlife that oak trees support.
“I don’t think I’ve come up with a more important tree in our woods, as far as its importance to wildlife,” said Abugattas. “More than 600 different species depend on oaks. Caterpillars, birds, bears, turkeys, deer.”
And of course, the squirrels. Although this year seems to have been an overall down year for the local squirrel population, Abugattas offers a reminder of how quickly it could see a resurgence.
“Squirrels are rodents, so like other rodents they can reproduce fairly quickly. If they have an adequate food supply they can reproduce twice or three times per year,” he said. “In fact, we’ve probably just had another batch born. Again, it’s all anecdotal at this point, but we could see the population bounce back in many areas rather quickly.”
The National Weather Service has issued a flash flood watch for Arlington and the rest of the D.C. metro area. It remains in effect until 2:00 a.m. on Wednesday.
Rain is expected to continue through the evening and the area may also see thunderstorms.
