PRINCETON, NJ — An Extreme Heat Warning issued by the National Weather Service will remain in effect through the Fourth of July weekend, with Princeton officials opening cooling centers as dangerously high temperatures grip the region.
The warning is in effect from noon Wednesday through 8 p.m. Saturday for portions of northern Delaware, central and southern New Jersey, and southeastern Pennsylvania, according to the National Weather Service. Heat index values are expected to reach between 100 and 110 degrees each day, with the hottest conditions forecast for Thursday and Friday. Overnight lows in the mid-70s to low 80s are not expected to offer relief.
Officials are urging residents to stay cool, stay hydrated, avoid strenuous activity during the hottest part of the day, and check on older adults, young children, and neighbors who may need assistance.
Three cooling centers are available for residents seeking relief from the heat:
Residents are urged never to leave children or pets in a vehicle, even for a few minutes, as car interiors can reach lethal temperatures within minutes. Anyone who sees signs of heat stroke — including confusion, loss of consciousness, seizures, or hot, red skin — should call 911 immediately.
The National Weather Service also recommended that outdoor workers take frequent breaks in shaded or air-conditioned areas and limit strenuous activity to early morning or evening hours. Anyone overcome by heat should be moved to a cool, shaded location.
Residents without air conditioning or shelter from the heat can call 211 or visit their county or state health department website for assistance.
Here's the forecast for the next few days:
