SEATTLE -- The hottest day of our heat wave is expected Monday and an excessive heat advisory is in effect through Monday evening for the Everett, Seattle, Tacoma and South Sound areas.

Tuesday will be somewhat cooler but will still be relatively warm. A cooling trend will bring temperatures back toward normal by Wednesday.

High temperatures on Sunday reached 94 in Redmond and Sammamish and 93 in Carnation.

The heat was so intense in Renton it buckled a section of SE 128th St at the 16700 block

The record for July 1 at Sea-Tac Airport is 87 degrees, set most recently in 1995. And the record for July 2 is 92, set in 1968.

We'll be in the low 90s here but we're talking triple digit heat east of the mountains, said KING 5's Lisa Van Cise

In Spokane, weekend temperatures in the 90s are expected during the Hoopfest 3-on-3 basketball tournament. The event is expected to draw 28,000 players and up to 200,000 people downtown. They are being warned to drink plenty of fluids to avoid heat-related problems.

The downside of great weather is the risks some people take to enjoy it at rivers, lakes and beaches in Washington. Keep in mind the water in rivers, lakes and the Puget Sound is extremely cold.

On Saturday, a man was rescued from Lake Washington. On Sunday a water rescue was launched on the Stillaguamish River for a boy who went under.

Most hot weather deaths are from drowning because rivers are fed by melting snow, said National Weather Service meteorologist Chris Burke. You go in and get into trouble right away.
