The weekend washout along the East Coast continues on Sunday, with more heavy rain expected in the Northeast while millions of people from the Delmarva Peninsula to the Carolinas brace for the threat of severe weather, including possible tornadoes.

The East Coast deluge began Friday morning and brought rain to the Carolinas and mid-Atlantic before moving into the Northeast on Friday evening.

The rain continued into Saturday morning, and the region saw a brief break in the action later Saturday.

Soggy Sunday in the Northeast

The FOX Forecast Center said Sunday will be a wet and chilly day across the region as a low-pressure system tracks inland and pulls in the warm, moist air from as far south as South Florida.

This will increase the risk of heavy rain, likely producing region-wide rainfall totals higher than 1 inch.

The highest rainfall totals will be confined to coastal and interior northern New England, where more than 2 or 3 inches of rain could fall, with hourly rainfall rates higher than 1 inch possible.

s a result, there is a risk of some flash flooding for parts of Massachusetts, New Hampshire and southern Maine.

Farther south, there is also the risk of flash flooding in parts of New Jersey, eastern Pennsylvania, southern New York and the Baltimore and Washington areas.

Because of the threat of heavy rain, the National Weather Service issued a Flood Watch for most of New Hampshire, including the cities of Nashua, Manchester, Concord, Conway and Berlin.

In Maine, a Flood Watch is in effect in cities from Sanford through Portland, Augusta, Skowhegan and Farmington.

In central New York, Flood Watches are in effect for cities such as Elmira, Ithaca, Syracuse, Binghamton and Monticello.

Eastern Pennsylvania, New Jersey and Delaware are also included in a Flood Watch that will run through Sunday evening.

This watch includes Philadelphia, Allentown and Harrisburg in Pennsylvania; Atlantic City, Newark and Trenton in New Jersey; and Wilmington and Dover in Delaware.
