Mighty North Sea Storm Xaver Battering Denmark, Germany, and the Netherlands

For the first time since 2007, the massive flood gates that protect the Netherlands from the North Sea have been closed, as a mighty North Sea storm hurls a huge storm surge propelled by near-hurricane force winds against the coast of the Netherlands, Germany, and Denmark. Windstorm "Xaver", as it is called by the Free University of Berlin, has already killed one person in Scotland, where a truck driver was killed and four people were injured in an accident west of Edinburgh when high winds toppled a vehicle onto several cars. Winds gusted up to 142 mph overnight in the Scottish Highlands; many roads and bridges were closed, and all train services in Scotland were suspended; Network Rail spokesman Nick King said that "there's too much debris and too much damage to equipment to continue." At 2:55 pm local time Thursday, oil rig F3 in the North Sea about 200 km (125 miles) north of the Netherlands recorded sustained winds of 83 mph, gusting to 99 mph. These winds were recorded at an elevation of 49 meters (161 feet), so were stronger than the standard winds measured at 10 meters at most world airports. Oil rig Ula off the coast of southern Norway recorded sustained winds of 91 mph, gusting to 108 mph, at 2 pm local time. On the west coast of Denmark at St. Peter Ording Airfield, sustained winds of 58 mph were recorded at 2 pm local time. Winds at Sylt, Germany were 58 mph at 5 pm local time (see the Sylt, Germany beach webcam here.

Heavy wind damage likely
A squall line with severe thunderstorms has developed along a cold front that is sweeping across Northern Europe this Thursday afternoon, and these thunderstorms are bringing intense lightning, heavy rains, and damaging winds. The European Storm Forecast Experiment is warning of the risk of tornadoes with this squall line, and damaging wind gusts of up to 90 mph (145 kph) in the severe thunderstorms. The Thursday morning 00Z run of the European model predicted that Xaver would bottom out with a central pressure near 960 mb Friday morning; the GFS model had it stronger, at 956 mb. This will make Xaver stronger the October's Windstorm "Christian" (AKA the St. Jude storm), which bottomed out at 968 mb. Christian killed 18, and did $1.4 billion in damage. It is possible that the wind damage from Xaver will approach that of Windstorm Anatol, which hit Denmark, Southwest Sweden, and Northern Germany on December 3, 1999. Anatol had sustained winds of up to 91 mph (146 kph), killed 20 people, and injured over 800. Damage was $2.6 billion (1999 dollars) in Denmark, making it the costliest disaster in Danish history.


Figure 3. Severe weather warnings for Xaver from the European Storm Forecast Experiment.

3.5-meter storm surge predicted for Germany
The maximum storm tide of Xaver will be in Germany and Denmark, and will be unusually high, since we are only two days past the new moon. Fortunately, the German coast is well protected by dikes, which are about 8 meters high, and these dikes should be able to withstand Xaver's storm surge. The German weather service storm surge forecast made Thursday morning called for a storm tide of 3.5 meters (11.5') above average high tide in Cuxhaven and Bremerhaven during the high tide cycle early Friday morning. This is about 4.8 meters above mean sea level in Bremerhaven, which will be very close to the all-time record of 5.18 m above mean sea level set there in January 1976.

German storm surge history
The deadliest flood of the last hundred years in Germany was the "North Sea flood" in 1962 (16/17 February), where many dikes broke and 340 people were killed. In the Bremerhaven area, the dikes from the 1840s were just able to withstand the storm surge but were heavily damaged. Bremerhaven had installed storm surge gates at the mouth of the river Geeste in summer 1961 as a reaction to the 1953 flood in the Netherlands. That small-scale Deltaworks saved the city. After this catastrophe, the dikes along the German coast were strengthened. Just in time, as the highest storm surge of at least the last hundred years occurred in January 1976. In Hamburg, the 1976 flood was 4.35 meters (14.3') above average high tide, which is 6.45 meters (21.2') above mean sea level. This is 75 cm higher than the storm surge of 1962, but the dikes were strong and high enough in 1976 to withstand the flood. Thanks go to Dr. Michael Theusner of the German climate museum Klimahaus for these stats.

Also; driving on ice slicked roads is a no-go/dangerous proposition in such conditions.  If this system is headed your way later, you would want to make your store trips for supplies as soon as you can ahead of the storm.

Good Morning.  Walshy hit the nail on the head.  Ice storms equal potential massive power outages due to tree limbs and such breaking from the weight and downing power lines.  You couple that with no power in the wake of such a storm for a period of time, and folks really need to have generators to power heaters or plenty of wood in stock to keep their fireplaces going.  The alternative is having plenty of blankets and jackets to get through the aftermath.

Hopefully, folks further down South in the lower Mid-West, including parts of North Texas have prepared for this system.

Quoting 462. KEEPEROFTHEGATE:


My Brother lives in Carbondale. Said they had a little ice (0.1-.2") to start then, sleet(1"), then snow and still snowing (8"). I would not at all be surprised at some 10-20" totals.



Widespread 8-10" reports already as of 7am this morning south of I-64 in Southern Illinois, and also Southeastern Missouri.

Still have all this to swing through withthe second shortwave. Very impressive system. A lot of people are going to remember this one.

Norfolk floods: Seven Hemsby homes destroyed by waves



Seven cliff-top homes were washed into the sea as the biggest tidal surge in 60 years hit the Norfolk coast.

The properties were destroyed overnight in Hemsby during storms along the east coast of England.

Ray Mooney, who was inside his home as the storm hit, said: "I heard a crash and whole back part of the floor caved in. Everything went down."

He said he was assessing the damage but expected the property to be either demolished or washed out to sea.

"This is my only asset," he said. "That's it, I haven't got anything else.

"I had just done the house up to sell but now I have nothing. I'm homeless."

Steve Connelly, 54, and his wife Jackie, 64, managed to rescue their three-month-old kittens Tom and Jerry before their home nearby was also destroyed.

Mr Connelly, who bought the two-bedroom bungalow in Beach Road, for £59,000, said: "We were in the pub when we heard the cliff was going so rushed to get what we could out."

He said residents formed a chain to help them rescue furniture and some belongings.

"People we've never even met were helping out, it was amazing.

"Suddenly we heard a shout 'it's going, it's going' and we watched our kitchen get ripped apart. The whole house collapsed before our eyes.

"We're devastated at what we've lost but at least me, Jackie and the kittens are safe."

The land on which the homes stood 30ft (9m) above the shore has been washed into the sea.

"This bungalow has fallen off a cliff", says Jo Black outside Steve Connelly's home
The seven families, now homeless, have been given emergency accommodation.

In Cromer, part of the sea wall collapsed and the pier was closed for safety reasons.

Jason Holland, from Cromer Coastguard, warned: "People are putting their lives at risk by trying to get equipment from their beach huts. People should stay away."

Norfolk Police Supt Stuart Gunn warned people to stay away as the huge waves could be carrying boulders or other heavy debris.

Much of this had crashed onto Cromer Pier breaking slates on walkways into pieces.

The Coastwatch station at East Runton had to be abandoned after the cliff on which it stood collapsed.

Secretary Ian Arnold said: "All of a sudden the cliff gave way and all that was left was the fence hanging over the waves."

Thousands of people spent the night in emergency centres after leaving their homes because of the weather.

Waves pounded the coast, bringing down many sections of cliff from Hunstanton in the north west of Norfolk to Hemsby in the south.


Cromer Pier, which was closed for safety reasons, has been partly flooded

Police have advised people to stay where they are as two more peak tides are expected in the next 36 hours.

The power went off on South Quay in Kings Lynn and parts of the town were underwater.

Firefighters rescued several people from floods in North Norfolk, King's Lynn, Bacton and Walcott.

Ch Supt Bob Scully, from Norfolk Police, urged people to stay in emergency centres if their homes had been evacuated.

He also warned people to resist the temptation of visiting flooded areas as they were still "hazardous".

Many homes have lost electric power because of flooding or high winds bringing down supply cables and engineers have been working to reconnect them where possible.

UK Power Networks said: "Where there are pockets of individual homes without power because they have been flooded, our engineers will switch the mains supply on again as soon as it's safely possible.

"But this could take some time as the water needs to recede first.

"Some homes may be part of the affected area even if they are not directly flooded."

Elsewhere in Norfolk:

A burger van floated away from Cromer seafront overnight - now lost at sea.

Because of damage to Cromer Pier, Pavillion Theatre shows have been cancelled until Monday at the earliest.

At least 30 beach huts have been destroyed along the town's seafront.

The car park attendants hut at Blakeney has been taken by the surge towards Cley.

Two caravans were washed onto the flooded road at Walcott.

The shingle bank at Hunstanton has been swept away.

Thousands of fish at Hunstanton Sea Life Sanctuary have had to be taken to facilities in
Weymouth, Dorset, after power to life support systems was lost.

The army was brought in to help protect telecommunications infrastructure in Great Yarmouth.

A MOSTLY QUIET WEATHER PATTERN IS EXPECTED ACROSS SOUTH FLORIDA
OVER THE NEXT SEVEN DAYS AS A STRONG MID/UPPER LEVEL HIGH PRESSURE
RIDGE WILL DOMINATE. THIS RIDGE AMPLIFIED IN RESPONSE TO A LARGE
UPPER LOW DEEPENED ACROSS THE NORTHERN ROCKIES/PLAINS STATES. THIS
RIDGE HAS ALSO PREVENTED THE ARCTIC AIR MASS OVER THE NORTHERN
STATES TO MOVE INTO THE FLORIDA PENINSULA WITH OUR TEMPERATURES
RUNNING A FEW DEGREES ABOVE DECEMBER AVERAGES. THE ONLY CHANGE TO
A DRY FORECAST IS THAT THE GFS AND ECMWF ARE SHOWING A SLIGHT
MOISTURE INCREASE ON SATURDAY NIGHT AS HIGHER PWAT VALUES MOVE
WEST AROUND THE PERIPHERY OF THE SURFACE ATLANTIC RIDGE. THE UPPER
RIDGE WILL BEGIN TO WEAKEN AND SHIFT SOUTHEAST BY THE MIDDLE OF
NEXT WEEK AS A COLD FRONT MOVES INTO NORTH FLORIDA. HOWEVER, IT
WILL STALL OUT ACROSS CENTRAL FLORIDA MOVING VERY LITTLE THROUGH
THURSDAY. THIS WILL MAINTAIN THE MOSTLY DRY FORECAST ALONG WITH
WARM TEMPERATURES.

EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
1259 AM EST FRI DEC 06 2013

VALID 12Z MON DEC 09 2013 - 12Z FRI DEC 13 2013


A SOLID RUN OF FOUR CONSECUTIVE ECMWF/ECENS MEAN SOLUTIONS FOR THE
MEDIUM RANGE BODES WELL FOR CONFIDENCE IN THE CURRENT FORECAST.
ANOTHER IMPRESSIVE COLD OUTBREAK IS SLATED FOR THIS PERIOD,
BEGINNING IN THE NORTHERN INTERMOUNTAIN REGION AND SPREADING TO
THE ATLANTIC COAST. THE SPLIT FLOW ALONG THE WEST COAST SHOULD
DIRECT AN ONSHORE COMPONENT SUFFICIENT TO BRING SIGNIFICANT
PRECIPITATION TO THE PACIFIC STATES. A WAVE OF LOW PRESSURE IS
EXPECTED TO PASS ACROSS THE DEEP SOUTH LATE IN THE FORECAST,
TRACKING TO THE CAROLINA COAST. THIS SYSTEM MAY HAVE ENOUGH COLD
AIR AVAILABLE FOR SNOWFALL TO THE NORTH OF ITS PATH. OTHERWISE,
THE BIG NEWS WILL BE ANOTHER ROUND OF MUCH-BELOW-NORMAL
TEMPERATURES FOR THE NORTH CENTRAL STATES.

Quoting 490. Walshy:
If I see 0.5 becoming a reality I think I might leave the area. I have no generator and pine trees are everywhere around here. Usually with .2 of ice I have to get in the incoming lane because they bend over the highways. I don't want to see what .5 will do. Usually cold air damming will bring more snow/sleet...but that does not appear to be the case this time.


I already bailed from Memphis where widespread power outages due to ice and high winds are forecast. Happily I have clients in central Mississippi so I just packed it in last night. Will head down to the Big Easy until Tuesday when I shall return to do more work in Meridian. Everyone laughed at me but I have to have electricity and an Internet connection to deliver reports on time!!

Worried here in North Carolina.

500-1,000 pounds of weight on the powerlines possible Sunday from .25 to .50 of ice. I live just south-east of the blue ridge where cold air damming is the most intense.

CNTRL/ERN GULF COAST INTO WESTERN CAROLINAS... ON THE WESTERN PERIPHERY OF LOW-LEVEL RIDGING ASSOCIATED WITH THE MID-LEVEL SUBTROPICAL RIDGE...A RETURN FLOW OF MOISTURE OFF THE GULF OF MEXICO INTO THE SOUTHEAST IS EXPECTED TO CONTINUE...WITH PERHAPS ANOTHER SURGE OF RICHER MOISTURE. MUCH OF THIS MAY OCCUR ABOVE/TO THE COOL SIDE OF THE SHALLOW SOUTHEASTWARD ADVANCING SURFACE FRONT...BUT SEASONABLY HIGH BOUNDARY LAYER MOISTURE PROBABLY WILL BE MAINTAINED IN AT LEAST A NARROW PRE-FRONTAL CORRIDOR. MODELS SUGGEST THAT THIS WILL SUPPORT WEAK TO MODEST CAPE...AND AN ENVIRONMENT CONDITIONALLY FAVORABLE FOR SEVERE STORM DEVELOPMENT...INCLUDING SUPERCELLS...IN THE PRESENCE OF SUFFICIENT DEEP LAYER SHEAR. GUIDANCE SUGGESTS WARM SECTOR SHEAR...BOTH DEEP LAYER AND LOW-LEVEL...MAY EVEN BE A BIT STRONGER THAN YESTERDAY.

Very odd that Texas is colder than Vermont, and also that the NWS forecast for us predicts naps:

COLD AIR WILL FILTER IN FROM THE
NORTHWEST...TRANSITIONING RAIN TO SNOW...WITH BRIEF PERIODS OF
SLEEP AND/OR FREEZING RAIN
