Excessive Heat Warning Issued for Portland

PORTLAND, Ore. – UPDATE (5:30am Wednesday) The Excessive Heat Warning remains in effect for the Portland Metro area until Thursday night at 11pm. Forecasters say we can expect hot and hazy conditions for a couple more days, until we get a little relief starting Friday. We won’t break any daytime high records, but we might break a couple of the morning low records with 67-degrees overnight the next two nights. Cooling centers are open in Multnomah County, Washington County and beyond. Don’t forget your local library may be the closest cool spot to you.

Forecaster Amanda Bowen with the National Weather Service in Portland says we could hit 100 today and tomorrow and we’re not going to cool off very much overnight.

Chris McGinness at News Partner KGW has this Seven Day Forecast today:

TODAY…………….. Sunny Hazy Hot 99
THURSDAY……………. Sunny Hazy Hot 97
FRIDAY…………… PM Clouds 79
SATURDAY………………. Am Showers to Cloudy 78
SUNDAY……………… Sunny 91
MONDAY…………….. Sunny 89
TUESDAY…………. Sunny 90

Many are heading to the coast to cool down. The popular local swimming holes are packed right now. People have been flocking to High Rocks in Gladstone. This year First Responders say they’re seeing fewer people get into trouble in the water. Officials say water levels and water temperatures may be the reason, but they say there are still hidden dangers below the surface of the water. First Responders urge swimmers to always wear a life-jacket, and don’t wear jeans. Denim can get heavy and weigh you down in the water making it difficult to swim.

 

Is your A/C working overtime in this heat? When it gets this hot air conditioners may struggle to keep your place cool. KGW asked an A/C repairman what you can do make sure yours is working as efficiently as possible. He says the key is having good air flow throughout your system. Keep the filters clean so the air can flow. Sam from “MP HEATING AND AIR CONDITIONING” also says your A/C will work better if you keep it on all day and not just turn it on when you get home.
