The 11pm update from the National Hurricane Center shows that Sandy has made little change in her intensity over the past several hours. Sandy remains a category 1 hurricane with a central pressure of 950mb. She is still forecasted to hook left Monday and make landfall along the New Jersey coast late Monday. At or near the time of landfall Sandy will make the transition over to a post-tropical cyclone. I think the biggest story is still the unbelievable size of the storm. The NWS is even calling it "the most impressive wind field in recent history."
That being said I think our biggest impact from the storm will be the winds. Winds will start to increase Monday morning, but really intensify Monday afternoon in Monday night. Strongest winds expected Monday night around the time that she makes landfall. Along the coast wind gusts could get up to 60 or 70 mph. Especially along the southern coast. Inland locations will also experience strong winds with gusts up to 50 mph. Widespread power outages are likely with this storm so please plan for the possibility of several days without power. Winds will start to weaken through Tuesday morning, but it will remain breezy through the rest of the week.
With the strong winds also come some bands of heavy rain. The heavy rain will start to move in from the south mid afternoon Monday. Rain will continue through Tuesday. Almost all of Maine and New Hampshire is under a flood watch with rainfall amounts through Tuesday of 1-3". My major concern with flooding is for the mountains and foothills where we could have some localized heavier amounts of rain up to 5".
Coastal flooding also may be an issue around the time of high tide. We have a full moon Monday night so tides will already be running astronomically high. Storm surge of 2-4' is possible around high tide Monday just before midnight.
Extended Forecast - The remnants of Sandy will continue to weaken through the week as it slowly lifts to the north. Our weather will still remain unsettled through Friday with clouds, breezy conditions, and showers. It won't be until the weekend that we finally get to enjoy some sunshine. It's a trade off though. High temperatures will be significantly cooler.
