TULSA, Okla. (AP) - The National Weather Service has issued a heat advisory through late Wednesday for much of the state as stifling heat and humidity continue to affect Oklahoma this week.
An excessive heat warning is in effect also until late Wednesday for Tulsa County, where temperatures are expected to climb into the high 90s.
Heat index values in all of the affected areas will make it feel like it is between 105 degrees and 110 degrees.
Forecasters say people exposed to the extreme heat for a prolonged period of time may get sick.
People who work or spend time outside are being advised to take extra precautions, such as rescheduling strenuous activities to early morning or evening.
People should also wear light, loose-fitted clothes and drink plenty of water.
