Posted: Updated:

A heat advisory from the National Weather Service remains effect Monday for a major portion of Eastern Washington as temperatures are expected in the triple digits.

Keep to cool areas and do not leave children and pets in the car by themselves. Finally, make sure everyone gets plenty of water, including your pets.

The heat advisory is in place until 8:00 p.m. on Monday.
