Sandy's path has become more certain, and will likely make landfall around New York City Monday into Tuesday (October 29-30), while transforming into a midlatitude cyclone. This storm may become a historic storm, bringing more damage than "The Perfect Storm".
The storm will not grow in size, but the pressure will fall, winds and precipitation will increase. The storm may be at its strongest of approximately 950-960 mb as it makes landfall near New York City late Monday.
Strong winds will hit coast of Northeast, with highest winds reaching up wards of 60-80 km/h (40-50 mph), with gusts much higher. Over open areas, winds could easily reach 80-110 km/h (50-70 mph). Entire Northeast, including Canada, will be seeing rather high wind speeds of 40-60 km/h (25-40 mph), with higher gusts. Power outages are possible.
Heavy precipitation will increase changes of flooding, as over 250 mm(10 inches) of rain may fall. The heaviest precipitation will fall around Southern New York, Pennsylvania, New Jersey, Delaware, Northern Virginia, Eastern West Virginia, and Eastern Ohio. Other parts of the Northeast, including Atlantic Canada, may receive occasionally heavy rain as bands of moisture from Sandy sweeps through.
On the back end of the storm, colder temperatures will rush in, creating possibility of wet snow over the Appalachians around West Virginia, and parts of Ohio. Snowfall may reach as high as 30 cm (12 inches) over North-eastern West Virginia.
The system will stall over Pennsylvania, bringing cloudy showers and cooler temperatures for the next few days. For those without power, cooler temperatures near freezing may have devastating consequences.
It is advised to follow local news and government instructions. States of emergencies have already been declared in several states.
