State health officials have extended this week's ozone high-pollution advisory into Wednesday, and the National Weather Service forecasts a top temperature of 110 degrees.

NWS officials have put the Valley under an Excessive Heat Warning from Wednesday through Friday, June 5-7, saying temperatures could top out at 114 degrees at some point during that period.

Individuals without effective cooling and adequate hydration are at high risk for  heat stress or illnesses, officials said.

The state's pollution advisory recommendations include:

• Drive less, carpool, use public transit, or telecommute. 
• Fuel vehicles after dark or during cooler evening hours.
• Reduce wait time in long drive-thru lines.
