Excessive Heat to Impact New Jersey Wednesday & Thursday



Heat Advisory valid from Noon Jun 08 for Hunterdon, Middlesex, Morris, Ocean, Somerset, Southeastern Burlington, Warren, Western Monmouth [NJ] and Berks, Lehigh, Northampton [PA] until Jun 09, 8:00 PM.

Excessive Heat Warning from Noon Jun 08 for Camden, Gloucester, Mercer, Northwestern Burlington [NJ] and New Castle [DE] and Bucks, Chester, Delaware, Montgomery, Philadelphia [PA] until Jun 09 and 8:00 PM

Forecast:

96-99 on Wednesday across the area, isolated 100 degree reading possible

97-102 on Thursday, 100-102 has the best chance in the urban centers especially...

Heat Index Values higher...

Remember to drink plenty of fluids. During the warmer, daytime hours go to air-conditioned malls, libraries, movie theaters or any public place that is air conditioned. If a family member appears overheated, use cool compresses to cool skin. Do not hesitate to contact a physician if you have a health-related question.

Remember to check on elderly or home-bound neighbors, who may be susceptible to the effects of heat stress. Spend as much time as you can in cool surroundings. Use fans and air conditioners to cool your home. Slow down and take it easy. Physical activity produces extra body heat. Wear light-weight, light-colored, loose-fitting clothing made of a breathable fabric, such as cotton. Wear a hat or use an umbrella to protect your head and neck when you are outdoors. Drink plenty of water; don't wait until you are thirsty. By then, you may already be dehydrated. Watch what you eat. Avoid eating hot foods or heavy meals. Use your stove as little as possible (use a microwave instead) and cook during the coolest part of the day. Take cool baths or showers. Cool water can remove body heat 25 times faster than cool air.
Avoid drinking alcohol and soda, as these actually dehydrate you faster. Instead, drink water or sports drinks.

If you have heat stroke, this is how you can tell:

Mental confusion, delirium, chills, dizziness, loss of consciousness, convulsions or coma...

A body temperature of 105 degrees F or higher...

Hot, dry skin that may be red, mottled or bluish...

A strong, fast pulse....

Power Outages will be possible during the excessive heat Wednesday and Thursday. Transformers can fail from overheating. Transformers are built to dissipate their heat, but in extreme weather conditions with extreme heat, there is no ability to cool because temperatures remain high throughout the night. Problems are also magnified in the confined spaces of an underground electrical system. If there is a flaw or crack in the cable insulation, a short circuit could occur as the cables expand from the heat. Increased demand for air conditioning means more electricity flowing through electric lines. This causes them to heat up and expand or sag, and in some cases they sag into tree branches, causing a short circuit. They also can sag to the point where they can be caught by tractor trailors and the trailors pull the wires and related poles down. Some electric equipment is sensative to the heat knowing the consequences of certain temperatures. The equipment will automatically and safely shut down to protect itself and other equipment. High current causes stretching of cables, switches, and other equipment and can increase the size of minor flaws in insulation or connections. Electric equipment can be weakened by previous ice storms, severe thunderstorms, lightning, and wet snow events (all things we have seen earlier this year) causing circuit failures, making it more susceptible to an outage as it can no longer withstand the increased flow of electricity during periods of high demand.
