(Portland, Oregon) – The first heatwave of the season is about to hit Oregon and Washington, with some areas climbing into the 90s over the weekend. For the Oregon coast and Washington coast, some sections will be in the lower to upper 70s, while others may even breach 80 degrees.

Interestingly, the central Oregon coast will be warmer than the south coast, but up north, the upper Washington coast will tread close to 80 at times.

All this comes with some amount of warnings from the National Weather Service (NWS), issued for most of the western halves of both Oregon and Washington, and they include northern half of the Oregon coast and southern part of Washington's coastline as well. The heatwave may cause health problems for some, and rivers will be much colder than many will expect.

The NWS said you should check on your neighbors during such heat events to make sure they have ways of coping with it.

“If you have fans or air conditioning, now is a good time to make sure those systems are operating properly,” the NWS said.

A higher-than-usual snow pack will make rivers much colder and run faster, including those along the Washington and Oregon coastlines.

“Nearly every year, people die in rivers in southwest Washington and northwest Oregon due to cold water shock during the season's first heat wave,” the NWS said. “Hot temperatures can make the cool water seem tempting, but river temperatures in the 40s and 50s can easily result in cold water shock that can kill in minutes.”

It's been an unusually cool and wet spring, the NWS said, and finally summer is here. But it's starting off with a whopper on Friday and continuing through the weekend.

“For inland valleys, temperatures will reach well into the 80s Friday, possibly even reaching the lower 90s in some locations,” the NWS said. “Further warming will make afternoon temperatures in the 90s more widespread in the inland valleys over the weekend. Offshore flow will bring sunny skies and warm temperatures all the way to the coast, where highs will be in the 70s and 80s this weekend.”

Seattle will reach into the upper 80s over Sunday and Monday, while the northern Washington coast gets into the mid 70s over the weekend and then close 80 on Sunday.

On the southern Washington coast, much of the week will be mostly clear and in the 60s, with the weekend getting a little warmer.

The same is true for much of the north Oregon coast, from Seaside down through Oceanside.

Among the warmest areas will be the central Oregon coast, with sunny skies and highs in the 70s, sometimes edging close to 80.

Farther south, around Coos Bay and Bandon, you'll see the coolest temps, staying mostly in the 60s over the weekend.

In the “Banana Belt” of the Oregon coast, Brookings and Gold Beach won't soar much beyond the mid 70s, although Brookings already saw a 90-degree day this week.

Portland, south Washington and the I-5 corridor will be the hottest, hitting perhaps 95 over parts of the weekend. Thus, you can expect a large amount of traffic and booked up hotel rooms on most of the southern Washington coast down through Florence or Reedsport.
