Nor'easter of 2007 slowly winds down
The Nor'easter of 2007 peaked in intensity at 8am EDT today with a central pressure of 967 mb, and has begun a slow decay. At 4pm EDT, the low had weakened to about 979 mb, and was centered over central Long Island. The Nor'easter is forecast to loop across southwest Connecticut and than move south across western Long Island/New York City early this evening as is gradually continues to fill. The worst of the rains and storm surge flooding have already occurred in most areas, but moderate storm surge flooding, freshwater flooding, and high winds will continue to cause problems throughout the Northeast through Tuesday night. A secondary low pressure system is expected to develop Tuesday south of Maine, leading to an increase in winds and storm surge flooding during the high tide cycles on Tuesday along the Massachusetts, New Hampshire, and Maine coasts. Up to 2-3 feet of storm surge flooding is expected along the Massachusetts coast during high tide Tuesday night.
Winds
The highest winds at the coast from the storm were 67 mph gusting to 80mph at 2pm EDT on the Maine coast at Matinicus Rock. The highest winds on top of New Hampshire's Mount Washington were 112 mph, gusting to 138, measured at 11am today.
Rains
Central Park in New York City recorded 7.57 inches of rain yesterday, the most ever from a Nor'easter, and their second highest daily rainfall ever measured. The record was set on September 23rd 1882, when 8.28 inches fell during a slow-moving tropical storm. Rainfall had totalled 8.31 inches at Central Park by 9am today. Rivervale, NJ has had the most rain I could find thus far--9.3 inches.

River flooding
All-time record flood levels were recorded or are expected on the Ramapo, Rockaway, and Passaic Rivers in New Jersey. Many rivers were 4-5 feet above flood stage in New Jersey today.
Coastal flooding
A 4-5 foot surge along the western shores of Long Island Sound was the highest from the storm. Wave heights up to 29 feet were measured in Massachusetts Bay.
Snow
Up to 17 inches of new snow fell in the White Mountains of New Hampshire.
I'll post an update on the Nor'easter on Tuesday. My condolences to all those affected by the tragedy today at Virginia Tech, and by today's storm.

Any thoughts on Andrew being #62??
That storm changed building codes, warnings, Jim Cantore etc what do you guys think? What should be number 1? Katrina??
WASHINGTON — People directly affected by the storm that hit the Northeast on Sunday and Monday are entitled to a two-day extension for filing their tax returns, the Internal Revenue Service said Monday.
Impacted taxpayers will have until midnight Thursday, April 19, to file their taxes. For others, the deadline this year is April 17 because April 15, normally tax day, fell on a Sunday and Monday was Emancipation Day, a legal holiday in Washington D.C.
"Because this unusually forceful storm hit within 24 hours of the filing deadline, we are giving affected taxpayers 48 additional hours," IRS Commissioner Mark Everson said in a statement.
The deadline extension is aimed at helping those directly affected by power outages or public transportation problems such as flight cancellations that made it difficult for people to file their returns on time.
Affected taxpayers, in order to avoid incurring late fees, should mark their paper tax returns with the words "April 16 Storm," the IRS said. Those filing electronically can use their software's "disaster" feature if available.
A dying tropical cyclone brought 2”
of rain to the mountains and deserts of
Southern California during a very
strong El Niño event of 1901-02.
A tropical storm came up into the
Gulf of California and the
southwestern United States, giving the
mountains and deserts heavy rainfall.
Needles received 5.66” of rain, twice
the normal of seasonal rainfall. This
occurred during the El Niño of 1905-
06.
The remnants of a tropical cyclone
moved northward across northern
Baja California into the deserts of
southern California with rainfall of 1
inch at Riverside. This occurred
during the strong El Niño of 1914-15.
Four days of heavy rains from a dying
tropical cyclone brought flooding to
parts of the mountains and deserts of
southern California. Rainfall of 4.38”
fell at Tehachapi in 7 hours on 9.30.
This occurred during the El Niño year
of 1932-33.
4” of rain fell across the deserts and
mountains as a dying tropical cyclone
moved across Baja California into
southwestern Arizona. This was the
second tropical cyclone to affect
California during the busy month of
September 1939. A strong El Niño
contributed to the activity.
A tropical storm moved northward
into northern Baja California and
dissipated with rainfall of up to 4” in
the mountains on 9.30 and exceeding
4” in the mountains on 10.1. This
occurred during the El Niño of 1946-
47.
A hurricane moving north
northwestward just off the west coast
of Baja California moved
northeastward into northern Baja
California and dissipated. Moisture
from this tropical cyclone resulted in
rainfall of 2 to 5” in the mountains
and deserts. Many roads were washed
out in the Imperial Valley, but
otherwise no major damage occurred
in southern California. This occurred
during the El Niño of 1951-52.
A west-northwestward moving
tropical storm southwest of Baja
California dissipated. Moisture from
this storm resulted in rainfall of up to
2” in the mountains and deserts, with
most falling on 9.19. This occurred
during the El Niño of 1951-52.
O and the list goes on and on....

Quite true. Very strong correlation between strong El Nino events and tropical moisture in CA. La Nina can cause upper lows to form off the SoCal coast during the off-season (summer/fall), and funnel moisture from what few tropical systems may exist into the SW...
Here it is also frontnews.
My thoughts und prayers are with the people who have to experience such terrible things.
savedbygod - that is an absolut awfull experience, having your child shot at! Hope I never have to go through something like that!
Lightning 10, my personal opinion is that climate change (human caused, natural, or both) is causing California's climate to change on a more broad scale right now, which means that the normal weather associated with ENSO may not apply. (for instance, 04-05 being mostly ENSO neutral or very weak el nino, a stronger el nino in 06-07 bringing extreme drought).
I had a lot to say about this so I made a blog entry on my own page, since it is not related to the New York storm.
10 mm of juicy rain here in the last 24 hrs.
JOYFUL STUFF
Sorry to note the bad happenings in the US. Keep strong..........
Enough moisture has moved in and conditions look ripe enough for maybe a line of some type to set up, probably a broken line of thunderstorms around the I-35 corridor. Expect this to become more numerous in mid to late afternoon as this moves east and probably washing out in the Arklatex region early evening tonight.
Main threat should be strong winds and hail. SPC has a 5% chance of tornadoes. Low-topped supercells I expect which means quick and fast tornadoes if they do form.
Have a good day everyone.
