Waters rushed into subway stations, making for hellish commutes, and the flash floods killed two people in New Jersey and caused a house to explode in New Jersey. Climate experts expect flooding to worsen and threaten already-struggling infrastructure throughout the region.

The region was hit with heavy rain Monday evening, resulting in flash floods that not only impacted roads and air travel, but also the transit system.

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.

Police say 60-year-old Lubia Estevez, a food services cashier at Plainfield High School, was one of two people killed during Monday's intense storms.

An updated flood watch was released by the National Weather Service on Sunday at 10:25 a.m. valid from 11 a.m. until Monday 5 a.m. for Oneida, Seneca, Cayuga, Onondaga, Tompkins and Madison counties.
