Remnants of Hurricane Ida could soon bring torrential downpours to the five boroughs, capping off one of the wettest summers in New York City history with yet another "significant rain event."

The fast-moving storm is expected to arrive shortly after 6 p.m. on Wednesday, picking up intensity throughout the evening, before tapering off by morning. It could drop anywhere between 5 to 8 inches of rain on the city, with the possibility of flash floods. The city is currently under a travel advisory through Thursday morning.

David Stark, a meteorologist with the National Weather Service, said he expects the heaviest rainfall before midnight, with the possibility of isolated tornados.

Since hitting Louisiana as a Category 4 hurricane on Sunday, Ida — now a post-tropical cyclone — has moved northeast, lashing much of the Mid-Atlantic region. A confirmed tornado touched down in Annapolis, Maryland on Wednesday morning.

A spokesperson for Con Edison said the agency is preparing for possible outages caused by the storm. The MTA plans on deploying additional crews at flood-prone locations.

"The bottom line here is there's going to be a lot of rain," Mayor Bill de Blasio said at a briefing on Wednesday. "You're going to see those places that flood temporarily, be careful. As per usual, don't drive into a situation where there's heavy water, deep water."

New York City had already experienced its second rainiest summer on record, following the historic deluge brought last month by Tropical Storm Henri. The already saturated soil could increase the likelihood of flash flooding, according to the National Weather Service.
