Bracing for the Worst Heat Wave of the Summer

Expect temps to feel 100 & above in the afternoon

An Excessive Heat Warning is in effect for Philadelphia and immediate surrounding counties through at least Wednesday night.

The Heat Warning means people from Wilmington to Trenton can expect temperatures in the mid 90s mix with high humidity and dew points around 70 will make it feel upwards of 100 to 103 degrees each afternoon, according to the National Weather Service.

NBC10 First Alert meteorologist Bill Henley said the Warning could be extended through the end of the week as a heat wave continues.

In Philadelphia, Health Commissioner Donald F. Schwarz signaled the activation of the City’s special summer heat programs which include the operation of the Philadelphia Corporation of Aging’s Heatline.

The city’s Heatline will be open from noon until midnight on Monday and from 8:30 a.m. to 8 p.m. on Wednesday. You can call the Heatline at 215-765-9040. The Heatline could possibly extend as temps remain high.

Residents are urged to visit older friends, relatives and neighbors to make sure that air conditioners or fans are working and homes are properly ventilated.

Older people with pre-existing medical conditions are especially vulnerable during a heat wave. Other groups at risk are people with chronic medical conditions, pregnant women, small children, those who work in a high heat environment and those who are engaged in a strenuous physical activity.

If you don’t have air conditioning in your home, you should seek relief from the heat for at least some part of the day -- especially in the afternoon when it feels the hottest -- whether it be at a shopping mall, movie theater, senior center or any air conditioned public space. The Health Department also recommends the following to people of all ages in order to avoid a heat-related illness:

  • Avoid working or playing in the hot sun or other hot areas
  • If you must be out in the sun, wear a head covering
  • Use air conditioners and fans
  • Open windows to release trapped hot air
  • Consult with your physician if you’re taking regular medication. Some medications cause an adverse reaction to hot weather
  • Wear lightweight clothing
  • Drink plenty of non-alcoholic liquids, warm or cool
  • Maintain a normal diet
  • Shower or bathe in water that is near skin temperature
  • Don’t leave older people, children or pets alone in cars
