On Monday, Sandy brought heavy rain, winds and storm surges to the Northeast, causing widespread flooding and extensive damage to hundreds of communities, particularly in New Jersey and New York.
But the drenching from all that water varied greatly by region.
In areas south of Atlantic City, N.J., where the storm made landfall Monday night, the wind was pushing out toward the ocean. This prevented high storm tides along the Virginia, Maryland and Delaware coasts and in Chesapeake Bay. But the same arm of the storm that held the ocean at bay carried a lot of rain.
