Heavy snow, high winds, flooding for the Northeast; destructive Winter Storm Xynthia nears Europe
Posted by: Dr. Jeff Masters, 16:12 GMT 26. Únor 2010 +3
A major winter storm continues to pound the northern Mid-Atlantic and Northeast U.S. today, as a powerful 979 mb low pressure system stalled out over Long Island Sound brings heavy snow, flooding rains, and high winds to the region. The storm dropped more than two feet of snow over Eastern New York near Albany, and surrounding regions of Western Massachusetts and Southern Vermont. One location in Vermont, West Halifax, received over three feet of snow--38.5". Heavy rains in excess of three inches has fallen over large sections of Northeast, including 8.38" at Scarborough, Maine. Rivers have spilled out of their banks over sections of Connecticut, Rhode Island, Massachusetts, and southwestern Maine, resulting in many road closures. Sustained winds of 25 - 40 mph have been common all along the coast, with wind gusts in excess of 60 mph common in the Appalachian Mountains. The prize for most extreme weather goes to New Hampshire's Mount Washington. At midnight, the Mount Washington Observatory reported sustained winds of 104 mph, gusting to 123, visibility zero in moderate snow, and a temperature of 21°F.

Fourth greatest snow for New York City, and still accumulating
The storm has dumped 20.8" of snow on New York City's Central Park as of 1pm EST today, making it the 4th largest snowstorm for the city in recorded history. With another 1 - 3 inches likely for the city today, the storm should rank as the 3rd largest snowfall on record before it's over. According to the National Weather Service, the top ten snowstorms on record for New York City's Central Park should now read:

26.9" Feb 11-12, 2006
26.4" Dec 26-27, 1947
21.0" Mar 12-14, 1888
20.8" Feb 25-26, 2010
20.2" Jan 7-8, 1996
19.8" Feb 16-17, 2003
18.1" Mar 7-8, 1941
17.7" Feb 5-7, 1978
17.6" Feb 11-12, 1983
17.5" Feb 4-7, 1920


Figure 1. Total radar-estimated precipitation from this week's storm over Maine. A large swath of 4+ inches of precipitation has fallen on a wet snowpack, creating flooding problems.

Today's storm will linger and slowly weaken through Saturday, bringing an additional 6+ inches of snow over portions of southeast New York, western Connecticut, and western Massachusetts. The strong winds will die down by tonight, aiding the efforts of utility repair crews struggling to keep up with all the power outages created by combination of high winds and wet, heavy snow.

Next storm
The active storm pattern isn't going to change over the few weeks for the Eastern U.S. The next potential snowstorm will be Tuesday, and will affect the Southeast U.S. Although it is too early to be confident of the amount or type of precipitation this storm will bring, snow will be a possibility for northern Alabama, northern Georgia, and portions of North and South Carolina.

Destructive Winter Storm Xynthia headed for Europe
A large 1000 mb low pressure system named "Xynthia" is over the eastern Atlantic, and is expected to rapidly intensify Saturday morning into a meteorological "bomb" that will bring high winds and flooding rains to Portugal, northern Spain, and western France. The models are coming into better agreement now, and have shifted their position for the storm's maximum intensity eastwards. France is now in the bullseye, and the storm is predicted to be at maximum intensity on Sunday morning when it will be positioned over northwestern France. The storm's powerful cold front will sweep ashore south of the low, bringing sustained winds of 50 - 60 mph (80 - 95 km/hr) to the coast of France's Bay of Biscay, with gusts over hurricane force (120 km/hr). The central pressure at that time will range from 966 mb to 972 mb, according to two of our top computer models, the ECMWF and GFS. This is about the same intensify as last year's Winter Storm Klaus. Klaus, which hit northern Spain and southwest France January 23 - 25, was Earth's most costly natural disaster of 2009, causing $5.1 billion in damage and killing 26. Klaus peaked in intensity at 967 mb, and brought wind gusts of 120 mph (193 km/hr) to Formiguères, France, 125 mph (200 km/hr) to Portbou, Spain, and 134 mph (216 km/hr) to Port d'Envalira, Andorra. Meteo-France has put out a bulletin warning of the possibility of hurricane-force wind gusts on Sunday, and is recommending that residents limit travel and avoid the threatened areas if the forecasts remains on track. While the storm is not expected to be as intense when it moves over Portugal and northern Spain on Saturday, these regions will still receive tropical storm-force wind with gusts to hurricane force. The Spanish Meteorological Agency is warning of the possibility of 100 mph (160 km/hr) wind gusts over northern Spain on Saturday. The damage total from this weekend's storm over all of Europe will probably exceed $1 billion, making it the globe's second billion-dollar weather disaster of 2010. The first was the back-to-back blizzards over the U.S. Mid-Atlantic region earlier this month, which are being blamed for over $2 billion in insured losses, according to Eqecat, a risk management firm.

Portlight continues relief efforts in Haiti
The damage from last month's catastrophic earthquake in Haiti has now been estimated at $7.2 billion to $13.2 billion, according to a study released last week by the Inter-American Development Bank. This figure is 1 - 2 times the $7 billion GDP of Haiti estimated by the World Bank. In the face of such a massive disaster, every little bit of help is needed, and Portlight.org has been doing a fantastic job getting relief into Haiti for those who need it most. Below is a link to a 3-minute long piece E News did on Portlight's efforts in Haiti:

This afternoon, I predicted the chance for freezing rain, but the local weather forecast did not. I based my prediction off on the likelihood that snowsqualls would hit parallel to a snow band just ahead of a backdoor warm front, merging with the other snow band, so that the snowsquall precipitation would fall into the warm layer above the surface, melt, then refreeze at the thin cold layer just above the surface. Indeed, we did get a short period of freezing rain, but other than some icicles on cars' license plates it was barely noticeable.

Strong Earthquake, Tsunami Warning in South Japan
By THE ASSOCIATED PRESS
Published: February 26, 2010

Filed at 4:02 p.m. ET

TOKYO (AP) -- Japan's meteorological agency says a magnitude 6.9 earthquake hit off Japan's southern coast, and has issued a tsunami warning in the region.

The Meteorological Agency said the quake occurred off the coast of the island of Okinawa at a depth of 6.2 miles (10 kilometers) at 5:31 a.m. Saturday (2031 GMT Friday).

The agency predicted a tsunami up to 3 feet (1 meter) near the Okinawan coast. There were no immediate reports of damage or casualties.

Japan is one of the world's most earthquake-prone countries.

Concur. The long wave immediately after the event is pushing A LOT of water BUT a very low percentage of the total volume in deep water. Becomes a problem once the total volume reduces as it approaches a shore, especially a long gradual continental shelf. Without the long gradual slope, it can bounce back to deep water and eventually be absorbed which probably explains the earlier event in the NW US coast today.

Quoting CycloneOz:


I'm not so sure that a tsunami is motion of a large volume of water.

Instead, I think the energy of the earth quake is being transferred molecule to molecule...Newton's 2nd law?

The shock wave of energy releases up into a wave once the number of available water molecules is reduced.

I'm probably wrong, but I play alot of pool and I can see the energy of a tsunami transferring rapidly like that in its water environment.
You are not wrong, bad choice of word on my part. I should have said "moving" a lot of water not "pushing" at lot of water. The long wave moves a large volume of water not very noticable in deep water but once the shelf gets it, gravity takes over (oversimplified but...)

Toxic algae could be the next big threat
With a new theory surfacing that toxic algae rather than asteroids killed the dinosaurs, scientists are still trying to unravel the mystery of what caused a massive algae bloom off the Northwest Coast that left thousands of seabirds dead and may have sickened some surfers and kayakers.

The bloom, which stretches roughly 300 miles from Newport, Ore., north to the Canadian border, still persists, though it's a shadow of its September and October peak.

Whipped by waves and storms, the microscopic phytoplankton, which had turned the ocean a rust color, broke apart, releasing toxins and creating a meringue-like foam that coated the feathers of birds like spilled oil. Up to 10,000 birds died of hypothermia in September, and researchers are still trying to come up with a count for October.

Researchers are also checking reports that surfers and kayakers who came in contact with the foam may have suffered cold-like symptoms, including temporary loss of smell and taste. The toxins also may have become aerosolized and affected beachcombers. In another strange twist, pathologists performing necropsies found that some of the birds lacked normal bacteria in their stomachs and other internal organs.

"It's definitely a warning sign of something," said Julia Parrish, a professor of aquatic and fishery sciences at the University of Washington. "We don't know what."

Blooms of the single-cell, saltwater algae species known as Akashiwo sanguinea have been found in Puget Sound, the Chesapeake Bay and elsewhere around the world. The bloom off the Northwest coast, however, is huge compared with others. At its height, there were 1.5 million algae cells per quart of water. The bloom was up to 65 feet deep and miles wide.

In only one other instance — a smaller bloom in 2007 in California's Monterey Bay — have the cells broken apart to create a toxic froth. And this particular specie of algae usually likes warmer water than that found off the Northwest Coast.

No one is sure what ignited the bloom. Some scientists think it could be caused by climate change, which has raised ocean temperatures and made the water more acidic — both conditions could favor this algae species. Others say it could be the result of such weather conditions as El Nino or the Pacific decadel oscillation, a long-lived El Nino-like pattern of Pacific climate variability.
