After leaving behind a deadly path of destruction from Florida to North Carolina, Ian finally met its demise over the mid-Atlantic late Saturday as it contributed to a raw and miserable start to October. Now, AccuWeather meteorologists are tracking a new, non-tropical storm off the East Coast of the United States, fed in part by Ian, that they say will bring days of pounding surf, coastal flooding and windswept rainfall from Virginia to Long Island.
This latest storm, composed of pieces of energy leftover from Ian, will have a three-prong effect, according to forecasters. In addition to raising winds to near damaging levels in some communities, the storm will also enhance rainfall along the coast and prolong above-normal tides and their effects.
The breadth of the storm's impacts was evidenced by the sheer array of weather advisories that were in effect midday Sunday from the southwestern corner of Connecticut to the Outer Banks of North Carolina. The alerts ranged from coastal flood warnings to small craft advisories and high wind warnings.
"A prolonged stretch of strong and gusty east to northeast winds will pound many beaches along the Northeast and mid-Atlantic coasts into midweek thanks to the non-tropical storm offshore," AccuWeather Senior Meteorologist Dan Pydynowski said.
An area of high pressure to the north will combine forces with the coastal storm, helping to funnel high winds and shove more water into beach communities.
"This can lead to beach erosion and some coastal flooding around times of high tide. There is a bit of good news during this stretch in that the moon phase is such that it will not further enhance tidal flooding," Pydynowski said.
Coastal and bayside communities, as well as inland tidal waterways, can experience widespread street flooding with roadways becoming impassable as a result of 1-3 feet of water inundation above ground level. Properties amid these low-lying areas can experience water damage as a result of the flooding.
"Areas prone to taking on water during wintertime nor'easters such as Wildwood, New Jersey, and Norfolk, Virginia, will likely experience similar conditions through the first half of this week," AccuWeather Senior Meteorologist Alex Sosnowski said.
The farther north along the coast, such as in eastern Massachusetts, the lesser the likelihood of coastal flooding and beach erosion as this region will be farther removed from the storm's strongest winds. However, there can still be dangerous surf conditions affecting these beaches.
AccuWeather meteorologists expect winds to gust 40-60 mph along the immediate coastline from New Jersey to the Chesapeake Bay and Virginia Tidewater regions. These gusty conditions can blow down trees and power lines and result in some communities being left without electricity.
Locations that receive a soaking rainfall during the stormy stretch may be at a greater risk of experiencing some extent of damage due to the wind. Trees sitting in saturated soil have an even higher likelihood of toppling over even in a moderate wind gust.
The area of high pressure that will contribute to even stronger winds along the coast will also help to confine rainfall generally south of Interstate 80 and east of I-81 during Monday and Tuesday, as drier air moves across interior areas. Rain extended as far west as the upper Ohio Valley and the central Appalachians during the weekend.
Factoring in the rain and wind, AccuWeather RealFeel® Temperatures can dip into the 40s and even the 30s at times, a likely reminder to people who live in the region that Old Man Winter is not that far away, according to Sosnowski.
An advancing cold front, one of the most potent of the season thus far, is likely to finally push the coastal storm out to sea Wednesday into Thursday. Forecasters say this push of chilly air may bring the first snowfall of the season for parts of northern New England.
