Heat Advisory

Excessive heat will persist across the West, from the Desert Southwest to the Pacific Northwest, underneath a large ridge of high pressure.

Heat warnings and/or advisories are in effect for many major metro areas, which include Las Vegas, Los Angeles, Phoenix, Portland, Sacramento, San Diego and San Francisco.

Also a concern, is the threat for isolated dry thunderstorms from northern California into Oregon.

The National Weather Service in Portland has continued a Heat Advisory until 9 pm. on Wednesday, June 12 for our area.

  • MAXIMUM TEMPERATURES

Daytime high temperatures of 91 to 99 degrees today and Wednesday. Urban areas will be the hottest.

  • MINIMUM TEMPERATURES

Overnight low temperatures of 60 to 67 expected tonight/Wednesday morning. Urban areas will remain the warmest.

  • TIMING

Peak heating will be between 3 and 7 PM today and Wednesday. Temperatures will be slow to cool tonight, with the coolest temperatures around 5 a.m. on Wednesday.

  • IMPACTS

Hot temperatures and limited overnight relief will increase the chance for heat related illnesses, especially for those sensitive to heat. People most vulnerable include those who spend a lot of time outdoors, those without air conditioning, young children and the elderly. Heat stress is also possible for livestock and outdoor pets.

  • PRECAUTIONARY/PREPAREDNESS ACTIONS

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.
