Nor'easter pounds NYC area with high winds, heavy rain and coastal flooding. Here's what to know.

A high impact nor'easter arrived in the Tri-State Area on Sunday and is expected to linger through Monday, packing damaging winds, rain and coastal flood concerns.

New Jersey is under a state of emergency, along with New York City and the surrounding region.

Our First Alert Weather team has the latest update on the forecast. 

The bottom line

• A nor'easter is affecting the region from Sunday through Monday night
• Timing: 3 p.m. Sunday through roughly 9 p.m. Monday
• Coastal areas will bear the brunt of this storm
• Moderate to heavy rain is likely, especially at the coast. 1-3 inches, higher totals in some locations
• High winds, especially at the coast, gusting between 40-60 mph
• Moderate to major coastal flooding for all coastal areas
• Substantial beach erosion

Nor'easter timeline

The storm brought high winds, gusting to 55 mph, Sunday along the Jersey Shore, along with some coastal flooding.

Forecast models maintain that the storm will stall along the Jersey Shore for a period Monday. This will play out in the form of a widespread and long duration rain event, strong winds that spread inland away from the coast and a high threat of more coastal flooding.

Rounds of heavy rain and strong winds will pivot through the region through Monday night. In between the rounds will be some lulls in activity. 

The heaviest bout of rain was expected late Sunday into Monday morning. Wind gusts were also likely to be highest in the early hours of Monday morning.

The storm brought gusting winds of up to 40 mph to Westchester County, along with more than 1.5 inches of rain. 

A tree limb came down in New Rochelle, starting a fire. 

"The branch from the tree came down, hit the power line, started a fire," Will Skelly said.

That fire roared through an old storefront being used as storage, but a passing police officer saw what happened and quickly summoned help, sparing Skelly's home next door. 

"We could have roasted alive in there if the cop didn't come by and bang on the door," Skelly said. 

"It was raining really hard. It was really windy," New Rochelle resident Nikki Koos said. "I woke up at 5 a.m. and there was a tree on my car." 

That tree toppled electrical wires and killed power to multiple homes. Webster Avenue was closed for a time after a massive tree took down power lines and a transformer, which leaked cooling fluid and required a hazmat cleanup. 

After stalling along the Jersey Shore for most of Monday, the low will then slowly move to the east by Monday night. Lingering showers could last into early Tuesday, though. 

Temperature wise, there won't be much variation, with highs in the low 60s on Monday.

Rainfall totals so far

Rainfall totals could reach up to 3 inches for some places. 

The highest totals so far have been reported in Suffolk County, Long Island, where Baiting Hollow saw at least 2.62 inches and Dix Hills saw at least 1.54. 

Wind gusts could also reach up to 60 mph along the coast. 

The strongest gusts so far were reported down the Shore, where Harvey Cedars saw 59 mph gusts, and in Suffolk County, where Eatons Neck saw 57 mph.

Biggest storm threats

Being that it's the middle of October, most of the trees still have leaves on them. This makes them more susceptible to wind damage, as the added weight of the leaves weighs them down. With forecasted wind gusts potentially reaching the 40-60 mph range in some locations, trees are likely to be toppled, leading to home damage and power outages. 

As the storm is expected to linger over the region for several days, there will be higher than normal tides, and multiple high tide cycles during its duration. This will lead to several rounds of coastal flooding, which, in some cases, may reach 3 feet of inundation. Beach erosion is highly likely, as well. 

While the chance of localized freshwater flooding is certainly there, the rain will fall over a period of days. This would decrease the threat of flash flooding, even with several inches of rain possibly falling. The overall dry pattern of late also helps with this.
