Heat Advisory until 08:00PM

The National Weather Service in Saint Louis has issued a Heat Advisory, which is in effect from 1 PM this afternoon to 8 PM CDT this evening.

* HEAT INDEX VALUES...Up to around 105 due to temperatures in the lower to mid 90s, and dewpoints in the mid 70s.

* TIMING...Much of this afternoon and a portion of early this evening, between 1 pm and 8 pm.

* IMPACTS...The heat and humidity may cause heat stress during outdoor exertion or extended exposure. The very young, the elderly, those without air conditioning, and those participating in strenuous outdoor activities will be the most susceptible. Also, car interiors can reach lethal temperatures in a matter of minutes.



A Heat Advisory means that a period of hot temperatures and high humidity will occur. This combination will create a situation in which heat-related illnesses are possible, especially for those living in un-air conditioned homes or apartments. People in the Advisory area are advised to avoid poorly ventilated areas and prolonged work in the sun. Also, keep plenty of liquids on hand and try to stay in an air conditioned environment. Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to the early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing when possible and drink plenty of water. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency, call 9-1-1 immediately. Where's baby? Look before you lock! Young children and pets should never be left unattended in vehicles under any circumstances. This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes. People in the Saint Louis Metropolitan Area can get information about cooling centers or energy assistance related to the excessive heat by calling the United Way of Greater Saint Louis at 800-427-4626, or if calling from a land line phone dial 2-1-1. You can also call Cool Down Saint Louis at 314-241-7668.
