The slow-moving nor'easter already responsible for days of rain, stiff winds, rough surf, above-normal tides and beach erosion will continue into the weekend along part of the East coast of the United States.

While the storm was past its peak intensity as of Thursday, it continued to expand northward, sending rain into northeastern Pennsylvania, southern New York and southern New England, and westward, sending wet weather into the central Appalachians.

Despite less forceful onshore wind, the duration of the flow from the ocean will continue to drive rough surf, beach erosion and minor flooding at times of high tide through Sunday. Coastal waters will run about 2 feet above published tide levels from northeastern North Carolina to around New York City.

Most of the rain produced by the storm through the weekend will trend toward becoming light and intermittent with some areas having more of an occasional drizzle, rather than all-day deluge. However, there will be a few episodes of heavy rain, mainly along and east of I-95 from Virginia to New Jersey.

The storm will continue the potential for travel delays on the highways and at the airports due to poor visibility, rounds of windswept rain and low cloud ceilings.

Rather than move swiftly off to the east, the storm will crawl northward through Friday, stall then drift southward later this weekend into early next week.

Flooding occurred at time of high tide on Wed., Oct. 9, 2013, at Cupalo Park, near Millsboro, Del. Special thanks to Hunter Outten for this photo.

As the storm begins its southward stroll this weekend, dry air will filter slowly in from the north so that rain and drizzle depart, followed by a chance of a clearing sky from portions of Pennsylvania to northern New Jersey, southern New York and southern New England.

However, Chief Meteorologist Elliot Abrams cautioned, "With the weak sun this time of the year, it takes a deliberate flow of dry air to get rid of low clouds, once they settle in."

There is a chance for the same storm to reignite and move northeastward next week. However, the track, intensity and impact have yet to be determined for the mid-Atlantic and New England. If the storm were to restrengthen and move northward during the middle of next week, then it could have more substantial impact in terms of beach erosion and coastal flooding. Astronomical tides are the greatest during to couple of days prior to the full moon. The full moon is Friday, Oct. 18.
