The Heat Rebuilds

Oklahoma City, OK –

OKLAHOMA CITY (AP) The excessive heat that has enveloped Oklahoma has caused six deaths and is suspected in seven other cases.

The Oklahoman reports that the state medical examiner's office cited heat as having caused the death of a 91-year-old woman in Tulsa on Sunday.

The National Weather Service says an excessive heat warning remains in effect for 24 counties in the eastern part of the state until late Saturday. Tulsa, Muskogee, Pittsburg, Wagoner and Washington counties are included in the warning.

Forecasters say heat illnesses will be possible as the combination of hot temperatures and high humidity persists.

Oklahoma City recorded its 32nd day of 100-plus-degree temperatures on Sunday. The record was set in 1980, when Oklahoma City had 50 days over 100 degrees.
