BOSTON -- Another storm, possibly a powerful nor'easter, could develop south of Long Island late in the weekend and early next week, making for a very wet Boston Marathon.

The storm could bring heavy precipitation, strong winds and coastal flooding if it were to develop.

Storm Trak 5 meteorologist J.C. Monahan said there is the potential to have as much as 5 inches of rain from the storm, which is expected to begin Sunday afternoon and last, possibly, through Tuesday.

The winds will be quite strong from the east, she said, especially Sunday night into the first part of Monday. That brings the risk of coastal flooding during high tide Sunday night.

There is the possibility of heavier snow further inland and north into New Hampshire and Vermont.
