2) General movement is toward NE (045) at 14 mph
a) this motion is expected to continue today,

3) Top sustained winds near 75 mph w/higher gusts in squalls/t-storms, which hurricane force winds now extend out up to 175 miles from the center
a) tropical storm force winds extend out 520 miles from the center
b) so this is a very large storm system!!!

4) Minimum central pressure is down to 951 mb (28.08 in), which is 9 mb lower from 0500 edt this morning.
a) some strengthening possible in next 24-30 hrs before making landfall, but
b) Sandy will be transitioning into a powerful extra-tropical (nor’easter) type storm system

5) Overall, don’t see any significant change in the track and intensity of Sandy, during the next 24-36 hrs before making landfall
a) though may be just a tab faster, making landfall along central NJ coast during evening

6) Model guidance is still in good agreement with Sandy moving NE into this evening, then turning more N overnight and then N-NW to NW by Mon AM
a) a turn more W-NW is expected midday Mon, which
b) Sandy is expected to make landfall near the central NJ coast Mon evening, again just a little faster!!

7) No matter the exact track, sandy will have an historic impact on the NE coast with the worse conditions mainly Mon PM into Mon night

8) A storm surge up to 6-8 ft is expected from northern NJ coast into LI sound to Block Island sound to Cape Cod and Islands
a) a 4-6 ft surge will occur over eastern MASS, NH and Maine coasts

9) Max rainfall amounts will be mostly in the mid-Atlantic region, from eastern VA into MD, DE into southern PA
a) up to 6-12 inches possible, but
b) will be lesser amounts to N, 3-6 inches NYC area to 2-4 inches across much western New England
c) 1-2 inches or less possible for eastern MA into Maine

10) After making landfall, Sandy will continue moving W and weaken into southern PA by Tue AM

11) With Sandy off to the W, there will be a strong SE to S-SE flow into Tue AM, then greater improvements in conditions in the PM

12) Remnants of Sandy continue weaken and meanders around thru late Tue into Wed, then lifts N and NE during Wed and Thu
a) Brisk SW flow along most of the NE coast, and
b) There will continue to scattered areas of squally showers around

Expected impacts from Sandy

Coastal Maine and E coast of Mass…NE to ENE winds will increase late tonight and Mon morning. NE-E winds will peak late Mon afternoon and evening, just before the winds shift to E and ESE. Wind gusts to 60-65 kts possible along the ME coast, 65-70 kts along the NH coast and up to 70-80 kts along the MA coast. The storm surge and large waves will arrive Mon evening – this will force tides to run 4-6 feet above normal. Keep in mind, this is a long duration storm, so at least 2 high tide cycles will cause serious coastal flooding with the worst occurring Mon night.

ESE and SE winds will still be blowing 20-40 kts Tue morning, but will be improving Tue afternoon/

Cape Cod/Islands to Newport..NE to ENE winds will be increasing this afternoon and tonight. Winds will be blowing 30-50 kts by Mon morning. Peak wind speeds will occur late Mon afternoon and evening, just before the winds shift to ESE and SE. Winds will frequently gust to 70-90 kts late Mon afternoon into evening. The seas will be gradually increasing tonight and Mon morning, so the tides will have a problem diminishing after high tide. Storm surge and large waves arrive late Mon afternoon and evening with tides up to 5-7 feet above normal Cape Cod and the Islands to Block Island Sound. The Tue morning/mid-day high tide will also run 2-4 feet above normal. Tides in Narragansett Bay and Buzzards will not see the full effect of the wind waves on top of the surge, but even in the Narragansett Bay and Buzzards tides will run 2-4 feet above normal Mon night and 1-3 feet above normal Tue morning/mid-day.

Long Island Sound…A very serious coastal flood problem will be developing Mon afternoon and night. In addition, tides will be reluctant to fall after high tide until Tue morning. Tides could run 6-8 feet above normal, especially Mon afternoon and evening, which will also coincide with the strongest winds, where gusts to 70-90 kts are possible. In addition, there will be 3-6 inches of rain Mon afternoon and night. Winds and tides will finally improve Tue afternoon and night, but 2 high tide cycles could cause serious problems from Mon afternoon into Tue morning.

Chesapeake Bay…N winds will increase tonight. N-NW winds will peak at 40-60 kts Mon afternoon and evening. But…NW winds 25-35+ kts will also occur Mon morning and later Mon night into Tue morning. There will be an extended period of strong NW-W winds. In addition, 5-10 inches of rain is possible late tonight and thru Mon.

The next statement will be issued around 1800edt Sunday.

    Den kommer dra rakt över vår fabrik i New England som det verkar nu på måndag. Ser inte bra ut alls. Hoppas allt står kvar efteråt.

    Det finns nog fler där man kan se hur det utvecklar sig.

      Såg inga vindsurfare på kameran. Fast det var kanske för att det var mörkt.

      Surfarna är ju kända för att sakna omdöme och förstånd ;0)

    Ajajaj, HMS Bounty sjönk i natt.

    Ja, det är en replika av båten som kapten Bligh kommenderade och blev av med. Besättningen tog på överlevnadsdräkter när de tog in vatten och tappad “propulsion” igår i 20 m/s och 6 m våghöjd (=12 m mellan dal och topp).
    14 i besättningen är räddade, en hittad livlös.
    Här kan man se ytbärgarna arbeta.
    Hjältar.

      “6 m våghöjd (=12 m mellan dal och topp).”

      Så är det väl inte? Våghöjden är ju avståndet mellan dal och topp.
      Se definitionen av wave height: “the difference between the elevations of a crest and a neighbouring trough.”
