Portland, Ore. — (Updated) The National Weather Service has issues a Heat Advisory for much of the Willamette Valley including the Portland Metro area.

The Heat Advisory expires at 9 pm Wednesday.

High temperatures Wednesday are expected to be in the mid to upper 90’s.

Overnight lows only cooling down into the mid 60’s.

The National Weather Service says a Heat Advisory means that a period of hot temperatures is expected. Hot temperatures will create a situation in which heat related illnesses are possible. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sunshine, and check up on relatives and neighbors.

Take extra precautions, if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing when possible and drink plenty of water.

To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency, call 9 1 1.
