Keep yourself hydrated.  That's the advice from health officials as the hot, dangerous weather continues.  Emergency rooms have been busy with treating people overcome by the heat.  Anyone experiencing exhaustion or heat stroke shoud call 9-1-1 immediately. 

Schools are closed Thursday in some parts of Illinois as the state endures another day of extreme heat and humidity. Classes have been canceled in Jacksonville, Champaign-Urbana and Quincy as many areas will see triple digit temperatures. Extreme heat warnings are in place in many areas until Friday evening. On Wednesday, O’Hare International Airport recorded a heat index of 114, the highest mark in 24 years.

Those people visiting outdoor events are urged to drink plenty of water and spend time in air-conditioning.
