Dangerous heat will remain a concern for Fishers and Hamilton County even after the current Extreme Heat Warning expires Friday evening.

The National Weather Service in Indianapolis says the Extreme Heat Warning remains in effect until 8 p.m. Friday, with heat index values reaching as high as 110 degrees. A Heat Advisory will immediately follow, remaining in effect from 8 p.m. Friday until 9 p.m. Saturday, with heat index values expected to reach up to 105 degrees.

Hamilton County Emergency Management is urging residents to take extra precautions, especially with the holiday bringing outdoor events, gatherings and travel.

Officials say high heat can affect people quickly. Residents are encouraged to drink plenty of water, limit beverages that can contribute to dehydration, such as alcohol and caffeine, and pay close attention to how they feel throughout the day.

Anyone who begins to feel overheated, light-headed or unusually tired should get to a cool indoor space as soon as possible. If going indoors is not possible, people should seek shade and slow down until they recover.

The National Weather Service says heat-related illnesses increase significantly during periods of extreme heat and high humidity. Residents are advised to stay in air-conditioned areas when possible, avoid direct sun, and check on relatives, neighbors and others who may be vulnerable.

Officials also remind residents never to leave young children or pets in unattended vehicles. Vehicle interiors can reach lethal temperatures within minutes during extreme heat.

Hamilton County Emergency Management is asking residents to keep themselves, their neighbors and visitors safe as the holiday weekend approaches.
