Below is an energy propagation pattern map calculated by the MOST forecast model. Filled colors show maximum computed tsunami amplitude in cm during 24 hours of wave propagation. Black contours show computed tsunami arrival time.
What does Tsunami mean, and what’s the origin of the word?
11:00AM Update: A Tsunami Advisory is now in effect for three states. Oregon joins California and Alaska under the advisory. A Tsunami Warning continues for Hawaii and Mexico. The first waves are scheduled to hit

The snow continues to pile up from what some are describing as a “Winter Hurricane”. Over 50″ of snow has now fallen in the hardest hit areas of New York and Vermont.
For many the problem is not the snow, but the damage left behind from hurricane force winds that peaked anywhere from 60mph to 91mph yesterday. Over 250,000 electric customers remain without power this morning in the southern part of New Hampshire alone, prompting N.H. Gov. John Lynch to declare a state of emergency.
Here are some of the staggering snowfall reports from across that part of the country:
53.0″ Potter Howell, NY
52.0″ Woodford, VT
51.0″ Slide Mountain, NY
20.9″ New York City-Central Park

A massive and still powerful storm has dropped over 50″ of snow on portions of the Northeastern United States. This same storm brought Chicago a little snow overnight. For the very latest on the storm follow the link below to the WGN Severe Weather Blog
The extraodinary East Coast “Winter Hurricane” continues to slowly weaken as it spins over New England this morning, This storm is so large, its western edge rotated into the Chicago area overnight producing up to an inch of snow. Lake effect snow across portions of northwest Indiana puffed up snowfall totals there to two and one-half inches.
Here is a sampling of reports from across the Chicago region
2.4″ Valparaiso, IN
1.7″ Porter, IN
1.5″ La Porte, IN
0.5″ Crown Point, IN
0.4″ Oak Park

It’s a first for New Yorkers. Nothing like the parade of megasnows which have lambasted the Big Apple in February has happened before. The latest storm, one of three which have hit the region in just the past month, roared into the city late Wednesday on 30 to 40 mph winds and generated 33 hours of uninterrupted, often heavy snowfall. When the snow finally broke late Friday, New York had been smothered by 21 inches of snow while just across the Hudson River in New Brunswick, N.J., the tally hit an astounding 37 inches. Sparta in northwest New Jersey came in a close second recording 33″ of snow. To the northwest in the Catskill Mountain community of Woodridge in southeast New York, an off-the-charts 46.9″ of snow had occurred. In effect, more than a season’s worth of snow had fallen with a single storm over a day and a half’s time. New York City’s Central Park February tally of 37″ made it the city’s single snowiest month ever. The total eclipsed the previous single-month record of 30.5″ set in March 1896. Snow records in New York City extend back to 1869.
Storm winds hit 90 mph on New England Coast; 125 mph on New Hampshire’s Mt. Washington
Friday’s storm was devastating across sections of the mid-Atlantic and Northeast. Nearly a million homes and businesses in a multi-state region extending from New Jersey and Pennsylvania north across New England were without electricity, including 40% of the homes in New Hampshire alone. The huge storm slowed to a crawl Wednesday and Thursday as it became ensnared in an atmospheric blocking pattern. The “block” was produced by a pool of mild air to the north, which generated a stubborn high pressure system which impeded its forward motion. The system was forced to spin in place, sweeping vast quantities of moisture into the region. In the hardest-hit locations of coastal New England, that led to 8″ of wind-driven rain which arrived on gusts as high as 90 mph at Portsmouth, N.H. Mt. Washington clocked 125 mph winds. As the moist air swept westward into cold air, gargantuan 3 to 4 foot snows resulted.
Long cloudy spell to accompany Chicago’s February to March transition
The storm’s circulation transported snow westward into Ohio, Michigan and Indiana late Friday where 1 to 4 accumulations were reported. The westbound snow reached Chicago late Friday evening. A dusting to a half inch was expected Friday night into Saturday morning. The Atlantic moisture driving the snowfall is to hold here into next week and promises to shroud the final weekend of February in clouds with spits of snow and pockets of milder air aloft contributing to the chance of patchy drizzle.
The book on February 2010′s weather closes at midnight Sunday night. The month managed a peak temperature no higher than 42 degrees — making it the first February in 31 years unable to produce a maximum reading that low. By comparison, a 61-degree high was logged last February.
