heat watch

The National Weather Service office in Cleveland has issued an "excessive heat warning" through Saturday evening for all of north central Ohio, including Richland, Ashland, Knox and Crawford counties.

The NWS said heat indices ranging from around 105 to as high as 112 degrees will be possible Saturday afternoon. Air temperatures are expected in the mid to high 90s.

The weather service said consecutive days of heat indices near or above 105 degrees could have a cumulative impact on some individuals, especially those who engage in prolonged outdoor work or other activities.

Also, car interiors can reach lethal temperatures in a matter of minutes. Never leave pets, children, or the elderly unattended in parked vehicles. The extended period of high heat and humidity can worsen the effects of heat stress.
