Dangerous surf conditions continued Monday, bringing strong rip currents and beach erosion along many East Coast beaches.

Forecasters said more than 2 inches of rain were likely to fall in some spots. The greatest threat for major flooding was expected to be for Long Island and southern New Jersey. Floodwaters started to recede by Monday night, as the storm moved along.

Coastal flooding peaked Monday afternoon, according to the National Weather Service. A ground stop was issued at John F. Kennedy Airport through 2:45 p.m. due to winds, leading to lengthy delays. All NYC-area airports dealt with hundreds of delays, with LaGuardia leading the way with 648; JFK Airport had 340 delays, while Newark Airport had 311.

The main concerns from the nor’easter that continued to impact the tri-state on Monday were beach erosion and flooding on Long Island and South Jersey. NBC new York’s Greg Cergol and Ted Greenberg report.

Places like Avalon in Cape May County had already seen this and have been dealing with flooding since Sunday. Elsewhere in New Jersey, flood waters started to swallow up streets during Monday’s high tide. On Long Island, streets had flooded to the point that large SUVs attempted to drive through were getting stuck in the water.

Long Island and coastal Connecticut will also see the impact of high tide. After the next few high tide cycles, we will see the levels start to go down, but until then, we will likely continue to see minor to moderate coastal flooding.

High wind advisories were dropped Monday morning for the area, but lingering gusts can still potentially bring down trees, which could cause power outages. As of 8:30 a.m., power outages in the tri-state total 32,080.

New Jersey has been under a state of emergency since Saturday night. Meanwhile, New York Gov. Kathy Hochul issued an emergency declaration for eight southern counties Sunday evening. New York’s State of Emergency due to the nor’easter prompted organizers to cancel the NYC Columbus Day Parade scheduled for Monday.

In New York City, a 76-year-old woman was killed Sunday when she was struck by a solar panel that broke off from the top of a carport structure in an outdoor parking lot. Strong winds sent the panel flying about 20 feet through the air, the city’s Buildings Department said. Her name has not been released.

When it comes to the temperature, Monday will be in the mid to upper 50s.

Sunshine returns Wednesday and better weather follows for the rest of the week.
