NEW YORK CITY — As Tropical Storm Isaias is set to arrive in the New York area Tuesday, the city is prepared for heavy rains to bring flooding, especially in Lower Manhattan.

New York City officials said a two-foot storm surge is possible in Lower Manhattan, around the South Street Sea Port area.

In the days leading up to Isaias, emergency workers essentially created a temporary 1-mile rubber dam around the area.

Isaias timeline: See what to expect and when

The large, water-filled rubber tubes are meant to stop water from the East River from inundating businesses and homes in the area, like it did eight years ago during Superstorm Sandy.

During Sandy there was a 4-foot storm surge. Officials do not expect Isaias to have the same impact but do want to be prepared.

How New Yorkers can prepare for Isaias

NYC is expected to see rainfall totals of 2 to 4 inches, with areas north and west of the city seeing between 4 and 6, and coastal areas of Long Island and New Jersey seeing 1 to 2 inches.

Most of the heavy rain and winds are expected between noon and 5 p.m. Tuesday, with the storm heading north and out of our area by later Tuesday night.
