While Sandy blasts across southern New Jersey Monday evening, Boston and southern New England will still be battered by strong winds, locally drenching rain and coastal flooding.
Since Sandy is a large storm in terms of surface area, people should not just focus on the center for greatest impact and damage.
The storm is different than a typical nor'easter in that it will be very strong, very large and rolling inland from the east, like a hurricane. It will retain some features of a hurricane.
The strongest winds will occur Monday night into Tuesday morning.
Gusts of 60 to 70 mph will blast the South Coast. Gusts of 50 to 60 mph are expected in Boston and northern Massachusetts.
Some rain will fall on New England, but the heaviest of Sandy's rain will target the mid-Atlantic.
Rainfall of 1 to 2 inches are forecast over most of New England.
A storm surge of up to 3 feet is expected along Massachusetts' east-facing beaches, but will be higher along the South Coast of New England and significantly higher toward the New York City area. A storm surge of 1 to 3 feet will reach northward along much of the Maine coast. Astronomical tides will be the greatest Monday, due to the full moon.
Even though the worst effects are likely to be centered south and west of Boston, downed trees and power lines, coastal flooding, beach erosion and travel delays are to be expected.
