Flooding caused delays on multiple New York City subway lines Monday as torrential rain pummeled the Tri-State Area.

The heavy downpours wreaked havoc across the city with footage showing commuters overwhelmed by floodwaters in various subway stations.

Heavy rainfall flooded portions of New York and New Jersey, with videos on social media showing a subway station inundated with floodwaters.

Two people died in New Jersey after their car was swept into a brook. Public transit was largely running normally a day after the subway system flooded in New York. Officials warned aging infrastructure remained susceptible to extreme weather.

Much of the U.S., including North Carolina, has experienced a significant increase in intense rainfall and widespread flooding throughout July, often unrelated to tropical systems and impacting areas outside designated floodplains.

Another round of showers and thunderstorms is slowly moving across the Mid-Atlantic Tuesday evening, after intense rain set off dangerous flash flooding from Virginia to New York on Monday, leaving at least two dead and prompting dozens of rescues as water overwhelmed roads and subways.

The century-old system is being hit with more powerful and frequent storms, and it will take a multiagency effort to fix it.

The weather service said there's a "marginal" risk of flooding in portions of Nassau and western Suffolk, but nothing what's expected to the west and north of LI.
