Coastal flood advisory issued in NYC without rain in forecast – here’s why

NEW YORK (PIX11) – The National Weather Service has issued a coastal flood advisory for the five boroughs, but the reason isn’t because of rain.

The supermoon brought changes to the tide cycle and, in t urn, higher tides to the shore, a spokesperson for the National Weather Service told PIX11 News.

During full and new moons, the gravitational pull is greater and creates higher sea levels. Since this full moon is a supermoon, the gravitational pull is even greater, so sea levels along the coast will be higher and could cause flooding during high tide cycles.

The supermoon on Thursday was about 222,056 miles from Earth, making it the closest supermoon of the year.

A storm system just off the Virginia coast is also causing some higher seas, according to PIX11 meteorologists.

NotifyNYC issued coastal flood advisories for different parts of the five boroughs from 8 p.m. Thursday through 2 a.m. Friday. The agency warned of possible flooding on low-lying roads and properties near shorelines.
