A flood watch is in effect for Hudson County from 2 a.m. Sunday through Sunday night.

Tide High

The tide on the Hudson waterfront is expected to be higher than usual Sunday night, 5.5 feet at 8:53 p.m.

A hazardous weather outlook issued late Friday for Bergen, Essex, Hudson, Passaic, and Union counties says, "Isolated to scattered instances of flash flooding are possible Sunday afternoon into Sunday night."

That's because up to an inch and a quarter of rain is expected to fall in those counties throughout Sunday.

In September 2021, Hurricane Ida reached New Jersey as a tropical depression, yet took an estimated 30 lives, mostly in flash floods.

Different Storms?

Ernesto strengthened to a Category 2 hurricane as it approached Bermuda on Friday.

Hurricanes must have surface winds 75 m.p.h. or higher. See how hurricanes are categorized here.

For tropical storms, depressions, and waves, wind speed and other factors come into play. The National Weather Services discuss the differences here.

When does a storm become post-tropical? The NWS says, "A post-tropical cyclone that no longer possesses the convective organization required of a tropical cyclone and has maximum sustained winds of less than 34 knots [around 39 MPH]. A non-frontal low pressure system that has characteristics of both tropical and extratropical cyclones."
