Sunday’s temperatures in the Portland area will hover near 90 degrees as the area enters what is expected to be an extended heatwave.

Monday’s high of 96 degrees will be a little hotter than predicted, according to the National Weather Service. But the real scorcher will be Tuesday, when there’s a 75% chance temperatures will be above 95 degrees and a 50% chance temperatures could climb to the triple digits.

Temperatures will start to gradually decline on Wednesday, when the high is expected to be around 99 degrees.

Multnomah County is expected to announce today whether it will open cooling centers this week, when Portland is likely to record its hottest temperatures so far this year.
