New York City and Tri-State could see flash floods, severe storms | Live updates

Ahead of Tuesday's forecasted storms, there are already hundreds of flight cancellations, and airlines have also issued travel waivers allowing passengers traveling to, from, or through airports in the northeast to rebook their flights without any extra fees if they were scheduled to travel on Tuesday.

Airlines typically cancel flights in advance to prevent travelers from being stranded at airports and to reposition their crews and aircraft out of the storm's path so they can restore normal operations as soon as possible once conditions are safe.

Ground stops and delays are expected at airports throughout the day as storms pass through.

Many airlines are allowing passengers to change flights to avoid the storms.

There's concern that parts of New York City could see the same kind of flash flooding that the area saw this weekend, especially residents in one part of Flushing, Queens.

They say the flooding is so common that they no longer buy nice things. Things that once surrounded them in their living rooms and bedrooms are being crushed up and carted away.

All the first floors of the homes along 153rd Street and Peck Avenue flooded, again, Saturday morning as sewage drains backed up in a deluge of rain.

The New York City Emergency Management commissioner visited the area Saturday afternoon, and Eyewitness News reported from there Saturday night after the flash flood receded. But a mess that happens in a flash can take days to get rid of.

NYCEM has activated the city's Flash Flood Emergency Plan.

This proactive approach includes targeted inspection and clearing of catch basins in flood-prone areas by the agencies like the Department of Environmental Protection and the Department of Transportation to help reduce street flooding before heavy rain begins.

New Yorkers should allow extra travel time during periods of thunderstorms and heavy rain. Do not remain in or return to areas or buildings that are flooding.
