\n

The heat dome that killed 29 people in New Jersey finally broke Monday morning, but it broke hard, with rounds of severe thunderstorms that brought flash flooding<\/a> to the tri-state area, stranded cars on highways, and collapsed part of the roof of a New Jersey warehouse store.<\/p>\n

Heavy rain caused part of the roof of the BJ’s Wholesale Club in Ocean Township, New Jersey to collapse Monday, sending a shopper, a cart, and tables of baked goods skidding through rushing water<\/a>. Two people were briefly trapped in debris but managed to escape, and no injuries were reported, according to the Monmouth County Sheriff’s Office.<\/p>\n

Flash flood warnings were issued for parts of New York City, northern New Jersey, and the Philadelphia region<\/a> as rounds of storms moved through the area. Heavy rain stranded cars on flooded highways across northern New Jersey.<\/p>\n

The transition from extreme heat to flooding has created a compounded risk environment for communities already stressed by days of record temperatures and nearly a million lost power connections.<\/p>\n\n

Why This Matters<\/h2>\n

A heat wave that ends with severe flooding does not produce clean relief. It produces a new set of hazards stacked on top of existing vulnerabilities.<\/p>\n

About 450,000 people remained without power across the country, most from storm damage, according to PowerOutage.us as of Monday morning. For households that lost power during last week’s storms and still have not had it restored, new storm systems carry the risk of additional damage to already-stressed utility infrastructure \u2014 and new flooding in areas where downed power lines have not yet been safely secured.<\/p>\n

Flash flooding is the most unpredictable weather emergency most people will encounter. Unlike heat or even tornadoes, flood conditions can develop within minutes and are often invisible from a distance until a driver or pedestrian is already in danger.<\/p>\n\n

What We Know So Far<\/h2>\n

BJ’s Wholesale Club, Ocean Township, NJ:<\/a> Part of the bakery-area roof collapsed; video showed rushing water pouring down and sending tables of baked goods and at least one shopper skidding. Two people briefly trapped but escaped without injury.<\/p>\n

Flash flood warnings were issued across parts of New York City, northern New Jersey, and the Philadelphia region.<\/p>\n

Heavy rain stranded cars on flooded highways across northern New Jersey.<\/p>\n

New York City Mayor Zohran Mamdani, who on Sunday warned about heat stroke and shared cooling center locations, by Monday urged people to leave basement apartments immediately if they saw water rising in their homes.<\/p>\n

Power outages as of Monday morning: approximately 450,000 customers still without power nationally, concentrated in Michigan, Pennsylvania, New Jersey, and New York.<\/p>\n\n

Where the Risk Is Highest<\/h2>\n

The immediate flood risk is concentrated in low-lying areas of northern New Jersey \u2014 particularly Essex, Bergen, Passaic, and Union counties, which include Newark, Hackensack, Paterson, and Elizabeth. These areas have older storm sewer infrastructure that was already saturated from last week’s heat-associated storms.<\/p>\n

In New York City, the mayor’s specific instruction to basement apartment residents to leave if water starts rising reflects the documented risk: New York’s belowground residential units flooded fatally during previous extreme rain events, and the city’s storm drainage system cannot fully handle extreme hourly rainfall rates.<\/p>\n

The compound risk for those 450,000 still-powerless households is specific: flood conditions in neighborhoods with downed power lines can electrify standing water. Do not walk through standing water in areas where power lines may be down.<\/p>\n\n

What Officials and Emergency Management Say<\/h2>\n

New York City Mayor Mamdani’s transition from a heat emergency message on Sunday to a flood safety message on Monday \u2014 within 24 hours \u2014 illustrates the speed with which the hazard environment shifted for the region.<\/p>\n

The National Weather Service New York issued flash flood warnings across parts of the metro on Monday morning<\/a>, with the most intense cells moving through northern New Jersey, Connecticut, and southern New York State through mid-afternoon. Flood conditions from the same storm system are expected to move into parts of New England and the Mid-Atlantic before Monday evening.<\/p>\n\n

What the Evidence Shows \u2014 and What It Does Not<\/h2>\n

The BJ’s roof collapse is attributed to the weight of floodwater on a structure that was not designed to support standing water accumulation \u2014 a failure mode that is not uncommon in large, flat-roofed commercial buildings during extreme precipitation events. The incident resulted in no confirmed injuries.<\/p>\n
