The Nor'easter of 2007 is steadily winding down, but will continue to bring high winds, minor coastal flooding, and up to one inch of rain to portions of the Northeast U.S. today. The nor'easter brought the heaviest rains since 1882 to New York City and northern New Jersey, triggering widespread flooding that will cost hundreds of millions of dollars. Hoboken, NJ became an island when roads surrounding the city flooded up to three feet deep, submerging cars, basements and parking lots. Over 1400 people were evacuated from homes along the Raritan River in New Jersey, which crested 10.5 feet above flood stage. At least 5000 people were evacuated in New Hampshire due to flooding, and over 400 roads closed. A woman and her 4-year-old granddaughter died when they were swept into fast-moving floodwaters as they tried to cross a washed-out section of a road in Lebanon, Maine, near the New Hampshire border. Winds gusting to 60 mph knocked out power to over 123,000 homes in Maine, the second largest power outage in state history. The record was set during an ice storm in 1998 that knocked out power to 340,000 homes.

Storm surges
Along the Massachusetts coast, tidal flooding has been minor to moderate, with overwash and erosion of dunes, flooding of coastal roads and some homes, but minimal damage to buildings. The peak storm surge in Boston at high tide was 2.2 feet yesterday, which added to the regular high tide to bring a 13.2 foot storm tide. Tonight's high tide may bring a storm tide half a foot higher, leading to moderate flooding. The new moon will bring a slightly higher high tide tonight than yesterday, and winds will remain gale-force, pushing 20-foot waves against the coast. Maine has already seen its highest storm surge from the storm--2.5-3.5 feet of surge during high tide yesterday. This was the fourth highest storm surge along the Maine coast since 1990. Storm surges of 1.5-2 feet are likely along the Maine coast during today's high tide cycles. Storm surges of 1-2 feet are likely at high tide today in New York City and Long Island Sound, which will cause additional minor to moderate flooding. The storm caused major erosion at Jones Beach, Robert Moses State Park and beaches in Montauk on Long Island.

Winds and snow
Tupper Lake, NY recorded 26 inches of snow. Winds gusts of 72 mph were observed in Milton, MA; 81 mph in Cape Elizabeth, ME, and 156 mph at Mount Washington in New Hampshire.

That is why I speak Hypothetically! Now until the middle of May, I look deep into EVERYTHING, as does everyone else. Patterns are setting up as we speak. Things change all season, I realize that but, come May 19th I will be able to give a pretty decent look on the season.

I got burned by that long range prediction so many times. I only take it one month at a time at most.

They might even have the sensitivity set differently for this evening, so maybe thats why its showing the funky returns
NWS in NYC plays around with the radar settings all the time

Even when you turn on "Hide Clutter",the radar still shows it.

Notice how only the Tampa radar is showing it.Clutter or an inversion would be on them all.

Could just be a problem with the radar programs.Not the actual returns,but a problem with how they're being read.

Well! If one wanted to draw conclusions to the latest long range CPC PRECIPITATION FORCAST for September and October. You could say that a strong bermuda high is expected, an active hurricane season for south florida is expected, and recurvature up the east coast is also expected. Purely my hypothetical opinion.

part of the reason the storm became so strong was do to a convergence of air masses: cold/cool to the north, warm/mild in the south

Almost in the same way the ENSO is behaving in the past couple years.

Weird that were i live in nystate(Pitcher) we have 16+inches of snow and just south and east in pa/jersey they have floods while north of us got over 2ft of snow. Had the temps been colder then in the 30's we would have had alot more snow too. The only that gets me is how did this storm get so powerfull this late in the year. We dont usually get this kind of snow in april.

Does anyone know if that disturbance that will form in the NE Carribean on June 19th will come into the Gulf, grow into a cat 2 and hit Tampa? -----That is one thing I hate about the idiots on this chat board.

LOL, same.

I usually don't post all that often. But there was an interesting article in the Miami Herald concerning Global Warming and hurricane intensity. Chris Landsea (gotta love the name) actually says GW will REDUCE the number and intesnity of storms because warming will also cause increased wind shear, just like el nino does today.

I give the Eatern Pacific a 1% chance of an above average season. I am just not convinced that La Nina will kick up anything extra special this summer. I think the only thing in the skys will be the AM clouds and Fog on the account of the cooler then average ocean waters.

I would like to note this is only if the La Nina kicks in into gear from know tell July.

I don't see much connection between upper and lower level in that East Pac storm. It's still early for the region. But not "way too early".

I keep an eye on EPAC for the off chance it will bring us some rain up here! Of course, active atlantic seasons that send storms into the gulf can also lead to some rain in southern California, especially the deserts. There was one case in 2005 where one of the tropical systems that hit texas actually maintained an upper-level rotation all the way across the continent to California... gave the thunderstorms a little 'kick'.

Certainly, if the year is a typical La Nina, that would favor the Atlantic.
