PORTLAND -- Warm temperatures in Portland Friday made it the hottest day of the year so far.

It reached 91 degrees in the Portland metro area, according to KGW Meteorologist Rod Hill.

On Sunday, temps. will get even hotter hitting 90 for the first this year, KGW meteorologist Nick Allard said.

The string of 90 degree days will continue through Tuesday, he said.

"Yesterday was the transition day," Allard said. "Today is the start to the real heat. In fact, if we get above 85­° today, it will be the hottest day of the year."

Doctors say to go out and enjoy the weather, but just don't over do it.

"With prolonged hot weather, what I tend to worry about is people who live at home and don't have air conditioners and might be older and might not be as active," said Dr. Ritu Sahni with Providence Health & Services.

TriMet anticipates having to slow down MAX trains due to the warm weather.

"In the heat, our overhead wires can sag and the rails themselves can expand," said Roberta Altstadt with TriMet.
