Between the snow already on the ground from the weekend's storm, up to two inches of rain falling by Wednesday and milder temperatures that will melt the snow, there is expected to be flooding across the region. Officials were asking residents to clear out their storm drains and areas around fire hydrants to help prepare for the deluge.

"If they know where the catch basins are in front of their house, it would be an immense help if they can go out and just clear away that catch basin," said Bob Ward, the director of public works in Haverhill, Massachusetts, on Monday.
