PORTLAND, Ore. (KOIN) — The heat is on.

As temperatures creep closer to 100 degrees, cooling centers opened across Multnomah County. A burn ban went into effect on Wednesday. Clackamas and Clark counties issued a total burn ban on Thursday afternoon.

An Excessive Heat Warning remains in effect through Saturday. A Red Flag Warning is in effect  through Saturday. Various lakes and rivers have algae blooms. Check the Oregon Health Authority’s page for the latest details.

Portland set a new record high for August 18, and more record-breaking temperatures are expected Friday and Saturday up and down the I-5 corridor. The hottest part of Friday will be 4 p.m. to 6 p.m., with highs topping out between 98 and 103. Temperatures will be warmest along the north coast Saturday, where the clouds move in last.  Along the I-5 corridor, expect temperatures between 98-103.

It may also possibly be the hottest day along the coast since 2012.

Fire danger will be very high as northeasterly winds pick up Friday, with gusts reaching 40 mph at the west end of the Gorge.

What Emergency Rooms expect

The hot, dry weather has emergency rooms preparing for an increase in patients. When temperatures skyrocket, hospitals often see a surge in heat-related illnesses that can be as extreme as strokes and seizures or less intense like heat exhaustion.

Some people come in for treatment of muscle cramps and mild dehydration when it gets too hot. Others may get traumatic injuries from being in the great outdoors.

“At the extreme end, people can get heat stroke… the elderly and young children are more at risk for that,” Providence St. Vincent Hospital ER Dr. Inna Shniter said.

Portland and Vancouver will experience some gusty conditions Friday morning with winds around 25 mph. Triple digit temperatures will be widespread inland, and a heat advisory will also be in effect for coastal areas from 12-9 p.m.

Temperatures are expected to hit the triple digits on Saturday and drop back down to the low 90s on Sunday. Cooler air will push inland at the beginning of next week and temperatures will start to drop with daytime highs returning to the low 80s.

Some models indicate another spell of hot weather late next week (Hood to Coasters beware!)
