Fishers and much of central Indiana will face another day of dangerous heat and humidity Thursday.

The National Weather Service has continued a Heat Advisory from noon until 8 p.m. Thursday, July 16. Heat index values—the combination of air temperature and humidity—could reach 102 degrees.

The advisory covers portions of central, east-central, north-central and west-central Indiana. The National Weather Service warns that the high temperatures and humidity could lead to heat-related illnesses.

Residents are encouraged to drink plenty of fluids, remain in air-conditioned locations when possible and avoid extended exposure to the sun. People should also check on relatives, neighbors and others who may be particularly vulnerable to extreme heat.

Anyone who must spend time outside should wear lightweight, loose-fitting clothing and take frequent breaks in shaded or air-conditioned areas. Strenuous outdoor activities should be limited to the early morning or evening whenever possible.

Symptoms of heat exhaustion may include heavy sweating, dizziness, weakness, headache, nausea or fainting. Anyone experiencing those symptoms should move to a cooler location, loosen clothing and drink water.

Heat stroke is a medical emergency. Warning signs may include confusion, loss of consciousness or a very high body temperature. Call 911 immediately if heat stroke is suspected.

Children and pets should never be left unattended inside a parked vehicle, even for a short time. Vehicle interiors can quickly reach deadly temperatures during hot weather.
