An Excessive Heat Watch is in effect Thursday, June 20, at 6:00 am through Sunday, June 23 at 8:00 pm. This Watch covers the same area as the advisory to highlight the anticipated long duration of excessive heat impacts into this weekend.
The excessive heat will build through the week with the most significant impacts occurring at the end of the week into the weekend. The excessive heat will continue through Sunday, with a cold front possibly not moving through until Monday of next week. Heat indices should reach or exceed 100° F for many areas Thursday through Sunday.
LOCATION AFFECTED: Eastern Pennsylvania, New Jersey, Delaware and Maryland
TIMING: Excessive heat (heat wave) lasting through at least this weekend. The hottest temperatures and greatest impacts are forecast to occur later this week through Sunday.
WATCHES, WARNINGS, AND ADVISORIES:
Air Quality Alert is in effect for Tuesday, June 18.
The New Jersey Department of Environmental Protection has issued a code orange air quality alert Tuesday for Southwestern New Jersey.
A code orange air quality alert means that air pollution concentrations within the region may become unhealthy for sensitive groups. The effects of air pollution can be minimized by avoiding strenuous activity or exercise outdoors.
Remember…
An Excessive Heat Watch is issued when there is a potential for the heat index value to reach or exceed 110° F (east of the Blue Ridge) or 105° F (west of the Blue Ridge) within the next 12 to 24 hours.
An Excessive Heat Warning is issued when the heat index is expected to reach or exceed 110° F (east of the Blue Ridge) or 105° F (west of the Blue Ridge) within the next 12 to 24 hours. An Excessive Heat Warning may be issued for lower criteria if it is early in the season or during a multi-day heat wave.
A Heat Advisory is issued when the heat index value is expected to reach 105 to 109° F (east of the Blue Ridge) or 100-104° F (west of the Blue Ridge) within the next 12 to 24 hours. A Heat Advisory may be issued for lower criteria if it is early in the season or during a multi-day heat wave.

HOW TO STAY SAFE DURING EXCESSIVE HEAT EVENTS
Outdoor Activities
Slow down. Reduce, eliminate, or reschedule strenuous activities until the coolest time of the day. Those particularly vulnerable to heat such as children, infants, older adults (especially those who have preexisting diseases, take certain medications, living alone or with limited mobility), those with chronic medical conditions, and pregnant women should stay in the coolest available place, not necessarily indoors.
Dress for summer. Wear lightweight, loose fitting, light-colored clothing to reflect heat and sunlight.
Minimize direct exposure to the sun. Sunburn reduces your body's ability to dissipate heat.
Eating and Drinking
Eat light, cool, easy-to-digest foods such as fruit or salads. If you pack food, put it in a cooler or carry an ice pack. Don't leave it sitting in the sun. Meats and dairy products can spoil quickly in hot weather.
Drink plenty of water (not very cold), non-alcoholic and decaffeinated fluids, even if you don't feel thirsty. If you are on a fluid-restrictive diet or have a problem with fluid retention, consult a physician before increasing consumption of fluids.
Do not take salt tablets unless specified by a physician.
Cooling Down
Use air conditioners or spend time in air-conditioned locations such as malls and libraries.
Use portable electric fans to exhaust hot air form rooms or draw in cooler air.
Do not direct the flow of portable fans towards yourself when room temperature is hotter than 90° F. The dry blowing air will dehydrate you faster, endangering your health.
Take a cool bath or shower.
HEAT SAFETY FOR OUTDOOR WORKERS
Outdoor workers can be at a higher risk to the effects of excessive heat. The Wet Bulb Globe Temperature (WBGT) is a good measure of heat stress during outdoor activities; learn more here. See Occupational Safety and Health Administration (OSHA) resources and recommended practices when working under hot conditions.
Drink water often
Rest and cool down in the shade during breaks.
Gradually increase workload and allow more frequent breaks for new workers or workers who have been away for a week or more.
Know symptoms, prevention, and emergency response to prevent heat-related illness and death
Check weather forecasts ahead of time to be better prepared.
