Powerful storm brings record snow to Southeast before it slams into New England, USA

Leconte
A powerful early season winter storm dumped nearly two feet of snow in the mountains of Tennessee and North Carolina on Saturday, a day after it flooded Chicago’s Lake Shore Drive by whipping up 22-foot waves on Lake Michigan. And this storm is just getting started.
 
By Sunday, an intense area of low pressure will be located off the coast of New England, causing heavy rain, snow and airport-snarling winds of 50 miles per hour or more from Long Island to Maine.
 
The storm has been termed a “Manitoba Mauler” by one National Weather Service office, due to its origins in the Canadian province of Manitoba. The record early season snows in the Southeast — this was the earliest measurable snow on record in Columbia, South Carolina — were the result of an unusually intense area of cold air and atmospheric spin in the upper atmosphere, which is known to meteorologists as an upper level low.

This low came out of Manitoba late this week and dove southeastward, spawning lake effect snow squalls and pounding lake surf in northeastern Illinois as well as parts of Michigan and Indiana. It then carved out a path all the way to South Carolina. The storm brought a near-hurricane force wind gust of 69 miles per hour to Gary Airport in Indiana on Friday, and caused hundreds of flights to be delayed or canceled at Chicago’s O’Hare International, one of the world’s busiest airports.
 
At a buoy in southern Lake Michigan, the wave height of 21.7 feet on Friday was the second-highest on record, according to the National Weather Service.

The track this storm has taken, with its wintry effects being felt all the way to the Gulf of Mexico, is rare for so early in the season. The snowfall totals so far have been stunning, with 22 inches of snow on Mount Leconte, Tennessee, which is in the Great Smoky Mountains, and widespread amounts of half-a-foot or more in the southern and central Appalachian Mountains.
 
This event broke the previous earliest trace of snow in Columbia, South Carolina by nine days. The previous record was set way back in 1913.
The upper level low pressure area is sparking the development of a strong surface area of low pressure off the Mid-Atlantic coast on Saturday night, and this will intensify as it spins its way northeastward, eventually parking itself over the Canadian Maritimes as a howling gale early next week.
 
The National Weather Service has hoisted high wind warnings along coastal areas up and down the eastern seaboard, as winds are expected to gust above 60 miles per hour in Massachusetts, New Hampshire and parts of Maine. Heavy snow, on the order of a foot or more, is forecast to pile up in Maine, while Providence, Rhode Island and Boston, Massachusetts may see a mixed bag of rain changing to a coating of snow.

With such a strong storm system, though, there are bound to be some surprises. For example, the coastal snow in South Carolina was not forecast far in advance.
 
The storm is also ushering in an unusually cold air mass to the Deep South, with temperatures on Saturday and Sunday running 20 to 30 degrees Fahrenheit below average. Widespread freeze warnings were in effect for Saturday and Sunday, with a moderating trend in temperatures forecast for the eastern U.S. next week.

Sinkhole develops under dam in USA; 7 nuclear reactors downstream; Water now seeping out

Gov’t notified of ‘stability issues’, plants begin evaluating potential flood impacts — Official: An ‘uncommon’ occurrence, we’re monitoring it continuously and working around clock — Structure same height as Niagra Falls
Inspection of [Tennessee’s Boone] dam revealed a sink hole… Six days later, an uncommon occurrence happened when seepage was found near the location of the sink hole at the base of the dam…
NCR; BOONE DAM STABILITY ISSUES… “TVA conducted a briefing for government officials… after discovery of a sink hole near the base… water and sediment [has been] found seeping from the river below the dam. TVA is continuously monitoring the dam… The dam is located upstream of all three TVA nuclear sites… The NRC Senior Resident Inspector was notified. The licensee is evaluating this event for potential impact on the design basis flooding level.”
Times Free Press; Tennessee Valley Authority engineers [will] search for the source of water seepage… Water and sediment were found Sunday seeping from the river bank below the dam.
TVA; A sink hole was discovered near the base… water and sediment was found seeping from the river bank below the dam…
John McCormick, VP at TVA; [We’re] exercising an abundance of caution… Unless it’s a huge storm, we can do what we need… we are continuously monitoring the dam… engineers want to be sure we understand what caused the sink hole and where the water and sediment is coming from.
WCYB; [A] sinkhole and seepage of clay particulates into the water at Boone dam… [is near] the bottom of structure on the river side of the dam… TVA employees are working around the clock to find the cause of the sinkhole and the source of the seepage. “The seepage into the waterway is not a common occurrence,” said McCormick… they do not have a definite timetable for finding the source of the seepage…
Boone Dam is just over the border from Virginia, where a powerful M5.9 quake struck in 2011 — Times Free Press: TVA inspects dams, nuclear plants after earthquake [and] is in the process of performing visual walk downs and inspections at… Boone
USGS; [Quakes] in the eastern U.S. can travel much farther and cause damage over larger areas than previously thought [and] damaging effects can extend over a much larger area… the farthest landslide from the 2011 Virginia earthquake was 245 km from the epicenter. This is by far the greatest landslide distance recorded from any other earthquake of similar magnitude… [This quake] occurred in an area 20 times larger than expected [and] landslide distances… are remarkable… [it’s] the largest distance limit ever recorded…

Tropical storm Vance is forecast to strike Mexico at about 01:00 GMT on 6th November 2014

Tropical storm Vance is forecast to strike Mexico at about 01:00 GMT on 6 November. Data supplied by the US Navy and Air Force Joint Typhoon Warning Center suggest that the point of landfall will be near 22.9 N, 107.0 W. Vance is expected to bring 1-minute maximum sustained winds to the region of around 64 km/h (40 mph). Wind gusts in the area may be considerably higher.
