Excessive Heat Warning Through Monday; Heat Advisory Through Friday Night for Oklahoma City (8/7/2011)


Excessive heat warning remains in effect until 10 PM CDT Monday. Heat advisory in effect from 10 PM Monday to 10 PM CDT Friday.

* Nighttime temperatures: 85 to 95 degrees much of the night, followed by only a brief dip around sunrise.

* Duration: Most locations have seen highs above 90 degrees every day for over 2 months. Highs above 100 degrees every day for 2 to 6 weeks. The heat has already proven to be deadly, and it takes an increasing toll with each hot day that passes.

* Some locations may not see highs of around 110 over the next few days due to cloud cover and a boundary across the region but temperatures and heat indices will still remain very hot in these locations. Elsewhere, temperatures of around 110 will still be possible over the next couple of days.

* Impacts: The risk of heat related illness continues to be very high. Avoid or greatly reduce outdoor work, sports practices, and activities. Try to remain in an air conditioned environment and drink plenty of water.

* Precautionary/preparedness actions: Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to the early morning or late evening hours. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight 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 911.
