The fourth day of stifling heat brought more of the same as New Jersey residents sought out how best to cope.

In Newark, Mayor Cory Booker called for a citywide heat alert. He was also concerned about fire hydrants that people opened up across the city.

?We had some serious water-pressure issues yesterday from people opening hydrants and that's not acceptable,? he said.

One Newark resident, a retired Army major, who served in Iraq, has no problem with the heat.

?[After] the heat from being in the desert, this is easy for me,? she said.

Some seniors headed to the Bethany Senior Center to keep cool. Pearly Campbell, who has lived in Essex County for 45 years, compared the heat here to what weather conditions she dealt with in South Carolina.

"You live in the country the dirt and the grass absorbs, so it makes it cooler,? she said. ?The cement holds more heat."

Forecasters say temperatures and humidity are expected to drop Wednesday.
