Powerful Nor'easter poised to hammer Eastern U.S.

Posted by: Dr. Jeff Masters, 4:23 PM GMT on December 18, 2009

An intense and very wet Nor'easter is gathering strength over the Gulf of Mexico, and stands poised to generate heavy snow and possible blizzard conditions tonight through Saturday from the Smoky Mountains to New England, including the major cities of Washington D.C., Philadelphia, and New York City. The storm has already dumped up to three inches of snow in western North Carolina, and a foot or more of snow is likely over the mountains of North Carolina, Virginia, and Tennessee. Flooding from the storms' heavy rains will be a problem in Mississippi and Alabama, where up to six inches have fallen (Figure 1).

Figure 1. Total rainfall from the Dec 18 - 19 Nor'easter, as estimated by Birmingham, Alabama radar.

Tornadoes threaten Florida
Severe thunderstorms capable of generating tornadoes have developed along the storm's cold front, which is advancing over Florida today. The Storm Prediction Center has placed most of Florida in its "Slight Risk" area for severe weather, and tornado warnings have already been issued for Homestead and Naples this morning, though no confirmed tornadoes have resulted from the warnings thus far. The threat of tornadoes will continue through mid-afternoon over Florida, then gradually decrease late this afternoon as the low-level winds align with the upper-level winds, creating less of the change of wind direction with height typically needed to create tornadoes.

You can track today's storm with our interactive tornado map and severe weather map.

Copenhagen
Our Climate Change expert, Dr. Ricky Rood, has left Copenhagen's COP15 climate change talks to resume his slightly saner life as a professor at the University of Michigan. His latest post, called The Party is Over: Copenhagen Devolved presents a fascinating look at what it was like to be at the conference, and what was (and was not) accomplished there. I'll be posting my own summary of the legacy of the Copenhagen talks early next week.

Hey, everybody, terminology/acronym question. A few times as I've looked at the forecast discussions for this "event", I've seen the term MDT, like this: Blv snow will become light tonight in the SW...but expeceted to continue at a MDT pace in I-95 corridor during the evening hours. Google search doesn't turn up anything that looks relevant. Any ideas? Member Since: July 8, 2005 Posts: 0 Comments: 40

They New York Airports will probably close as well. There will most likely be big disruption of travel along the NE corridor today. Be back in a minute.

Thanks, guyz! National Airport has one "lane" open. Dulles International has two. A few flights have gone out. There aren't too many planes on the ground here, so planes would have to come in to load them up. I know they'll keep National open as long as possible, because that's the one our VIPs often use, and subway stops there. Haven't heard any updates on BWI.

History buffs -- our biggest storm, Jan. 1922, the Knickerbocker storm (bldg. came down), 22" Wonder if we'll beat that...some places have that now...but I think it has to be official at National Airport, so maybe/prob. not. All Smithsonian Museum bldgs closed, first time since 1996. They will be closed tomorrow, too. That's sad because there's some school groups visiting.

Awwwwww, and it's just so cute (not really)... N. America's biggest fish slips toward extinction By MATTHEW BROWN, Associated Press Writer Thu Dec 17, 8:16 pm ET Link In part: BILLINGS, Mont. – As efforts falter to save North America's largest freshwater fish — a toothless beast left over from the days of dinosaurs — officials hope to stave off extinction by sending more water hurtling down a river so the fish can spawn in the wild. The U.S. Fish and Wildlife Service on Thursday declared that attempts over the past two years to save the endangered Kootenai River white sturgeon had failed. The prehistoric sturgeon, characterized by its large head and armor-like scales, can reach 19 feet long and top 1,000 pounds. An isolated population of the species lives along a stretch of the Kootenai that passes through Montana, northern Idaho and southern British Columbia. Fewer than 500 of the bottom-feeding behemoths survive — and it's been 35 years since they successfully spawned. The problem is Libby Dam, a hydroelectric facility in Montana run by the Army Corps of Engineers that serves power markets in the Pacific Northwest. When the dam went up in 1974, it stopped periodic flooding of Bonners Ferry, Idaho — but also high water flows that triggered the sturgeon to move upriver and spawn. After years of litigation, the federal government agreed to alter how it runs the dam and more closely mimic historical water flows. That hasn't worked, and fisheries officials and the Corps now say they plan to spill more water over the dam next spring. It could be one of the last chances to stave off disaster for the massive fish: Biologists say it could be on track for extinction within the next decade unless a fix is found.

OH! I got some great news yesterday (I think, LOL...remember, we're not supposed to be a dirty 4-letter word anymore, now that our leader is an experienced, respected guy from Florida Emergency Management! This has been approved! What a great job -- I get training, I get to help people and I even get paid (modestly, taxpayers, modestly)! I've worked Community Relations and Individual Assistance since '05, so I'm hoping this won't be very tough going. Congratulations, You have been nominated by your Cadre Manager to attend the first offering of the Policy, Procedure and Practice for External Affairs course. This is a four week course. Please review this document as it will provide you with valuable information on the course and registration policies. Course Goal At the conclusion of this new training sequence, participants will have completed a major segment of the necessary training to become basically qualified specialists as defined by the External Affairs Workforce Credentialing Plan. (Then it lists in-class training, and then on-site field work and mentoring. Course Descriptions: These courses are designed to provide the knowledge and tools necessary to perform job functions in FEMA External Affairs and Emergency Support Function (ESF) -15 operations. Taken sequentially, they will prepare participants to work seamlessly with other External Affairs components in delivering comprehensive, integrated, and unified messages to all stakeholders. Participants will be deployed to a Joint Field Office for a two week mentored field internship. Finally, an additional week of component-specific training will complete this four-week process.

Quoting Bordonaro: Good Morning TornadoDude and everyone :0)!! It's beginning to look alot like a BOMB for Saturday, for the E Coast this year..Have some snow, about 2 or 3 feet of it, 50MPH wind gusts, 985MB L, DC has had 8-12" already, 8-12" more for them. Get ready Philly, NY and DC now, for skiing in the streets!! Nothing like a generous helping of snow with your hot cocoa and marshmellows hey bord, is there supposed to be moisture that builds back into my area? cause it looks pretty gimpy but they still expect 2 to 4 inches tonight Member Since: September 6, 2007 Posts: 0 Comments: 4801

My friend is stuck in West Virginia right now on her way to Florida, and they can't drive because there's about two feet of snow on the ground. It also looks like some parts of the state are likely to get more than 2 inches per hour before the snow clears out. I'd like to ask, does WV have adequate snow removal services?
