People in central Pennsylvania will be hit with damaging wind and flooding rainfall from Sandy through Tuesday.
In the Keystone state and over much of the Northeast, the storm will threaten lives and property and will bring widespread travel disruptions.
Sandy is forecast by AccuWeather.com to make landfall near Atlantic City, N.J. Monday evening and to push inland over Pennsylvania late Monday night and Tuesday. However, effects from the powerful and massive storm will precede landfall, while impact will linger for days after the storm's demise.
The worst conditions will occur locally late Monday night into Tuesday.
Since Sandy is such a large storm in terms of surface area, effects will be more than a small category 1 or 2 hurricane hitting the coast or a nor'easter.
According to AccuWeather.com CEO Barry Myers, "Sandy is a hurricane wrapped in a winter storm."
There will be major impact due to wind and flooding as far north as portions of New England and as far south as Washington D.C. and Norfolk, Va. and as far west as the Great Lakes.

At this time AccuWeather.com meteorologists expect wind gusts in the neighborhood of 50 to 60 mph in central Pennsylvania. Gusts can be higher over the ridges, on top of buildings and through the gaps in the mountains.
Gusts this strong will down trees, power lines, send loose objects airborne and cause minor property damage.
Avoid walking or parking under trees as large limbs can come down with no notice.

The heaviest rainfall, a general 4 to 8 inches, is projected to fall over central Pennsylvania over a several-day period through Wednesday. The greatest amount of rain is likely to fall over northern Maryland and southern Pennsylvania. Flooding of the Potomac River mid- to late-week is likely as a result.
Enough rain will fall in the local area to raise the risk of flash, urban and stream flooding. Fallen leaves will block storm drains adding to the potential for street flooding.

Heavy snow will fall over the high ground in West Virginia and south central Pennsylvania.
Severe storms are shifting eastward Wednesday afternoon delivering strong wind, heavy rain and hail.
So far this year California has seen 1,569 wildfires, 85 percent more than in an average year.
The Memorial Day weekend will begin cool, windy and rainy in New England and part of the mid-Atlantic.
GOES-East failed again late Tuesday. It is one of the main satellites meteorologists use for the eastern part of the United States and the tropical Atlantic.
