Heat wave-breaking rain caused part of the roof of a New Jersey warehouse store to collapse Monday, sending a shopper, a cart and tables of baked goods skidding through rushing water.
Two people were briefly trapped in debris at the BJ’s Wholesale Club in Ocean Township but managed to escape, and no injuries were reported, according to the Monmouth County Sheriff’s Office.
Flooding rains were reported in parts of New York City, Philadelphia and New Jersey as rounds of storms moved through the area Monday, breaking a heat wave that gripped much of the area last week.
On Sunday, New York City Mayor Zohran Mamdani warned about heatstroke and shared locations of pools and cooling centers. By Monday, he was urging people to leave basement apartments immediately if they saw water rising in their homes.
Heavy rain stranded cars on flooded highways across northern New Jersey and sloshed water into businesses and at least one hospital.
“Nothing too serious. They have us running from call to call,” said Lakewood Police Capt. Leroy Marshall.
The rain and storms broke the heat dome that settled over much of the Northeast last week.
LaGuardia Airport in New York set a record high Thursday of 104 degrees Fahrenheit. Low temperatures in many places barely made it below 80 degrees F, preventing people from cooling off even at night.
The temperature at LaGuardia hovered just below 70 degrees F Monday with the rain.
Officials in New Jersey were investigating at least 29 deaths last week that were possibly heat-related. The people were found dead on the street or in homes without air conditioning. They ranged in ages from their 30s to their 80s, New Jersey Department of Health Commissioner Raynard Washington said.
Autopsies and other investigations will be needed before the deaths are officially blamed on the heat, Washington said.
Other states have not announced possible deaths from the heat.
Severe storms moved from Michigan to the East Coast as the heat wave broke over the weekend. About 400,000 people remained without power across the country, most from the storm damage, according to poweroutage.com.
