Excessive Heat Warning In Effect For Much Of Philadelphia Area

The National Weather Service has issued an excessive heat warning that will remain in effect until 8 p.m.

With maximum heat index values expected to reach 100 to 105 degrees, and maximum temperatures in the 90s today, officials are warning that the heat and humidity will become a danger if proper precautions are not taken.

The National Weather Service recommends taking extra precautions if working or spending time outside. If possible, reschedule strenuous activities for early morning or late evening. Wear light-weight and loose-fitting clothing and drink plenty of water.

If working outside, it is recommended that one schedule frequent rest breaks in a shaded or air conditioned environment. Anyone overcome by heat should be moved to a cool location.

Officials suggest drinking plenty of fluids, staying in an air conditioned room – or otherwise out of the sun – and checking on elderly relatives and neighbors.

In addition, children and pets should never be left unattended in a parked vehicle. The interior of a vehicle can reach lethal temperatures in a matter of minutes. Make sure pets at home have adequate water and shelter from the sun.
