June 29, 2018 GMT

The National Weather Service has issued an excessive heat warning for northeast Indiana and most of northwest Ohio from noon today to 8 p.m. Sunday.

An Air Quality Action Day has been declared in Allen and Huntington counties until 7 p.m. tonight. Ozone levels are expected to be in the unhealthy range for sensitive groups.

The weather service also issued a heat advisory for Mercer County, Ohio, from noon to 8 p.m. Saturday.

The excessive heat warning means temperatures will peak in the 90s today, Saturday and Sunday, with heat indices near 105 today and Sunday and around 110 on Saturday. Lows are to be in the middle 70s tonight and Saturday night.

The combination of hot temperatures and high humidity will lead to an increased risk of heat-related stress and illness, the weather service said. It said the very young, senior citizens, those without air conditioning and those participating in strenuous outdoor activities will be most susceptible.

The weather service encouraged that strenuous outdoor activities be rescheduled for early morning or evening. It said people should wear lightweight, loose-fitting clothing and drink plenty of water.

Young children and pets should never be left unattended in vehicles, the weather service said. It said car interiors could reach lethal temperatures within minutes.

In Mercer County, heat index values Saturday are expected to be around 100, with temperatures in the lower 90s.
