OMAK Triple-digit temperatures are expected to roll through portions of Okanogan County later this week, prompting the National Weather Service to issue a new heat advisory.
The advisory - which primary covers Brewster, Omak, Oroville and Wenatchee - will remain in effect from 1 p.m. tomorrow until 9 p.m. Friday.
“The heat will hit first in the southern portion of the Central Basin, southwest Palouse and along the Clearwater Rive, expanding northward into lower valley areas along the Columbia through Wenatchee and into the Okanogan Valley Thursday into Friday,” a prepared statement from the service said.
Meteorologists caution those who spend time outdoors.
“When possible, reschedule strenuous activities to early morning or evening,” meteorologists said. “Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing when possible and drink plenty of water.”
The advisory mirrors one issued last weekend, which later had in record-setting temperatures and a red flag warning due to increased fire risk.
Thermometers in Okanogan and Ferry counties topped off last weekend with record setting temperatures that soared well above 100 degrees.
According to the National Weather Service’s Spokane regional office, temperatures hit 110 degrees in the Omak on Sunday– a whopping 13 degrees hotter than the previous record set in 1992 at 97 degrees.
And the weather wasn’t much cooler on Saturday either.
The service reported a 2006 record of 100 degrees was shattered as thermometers climbed to 107 degrees.
The Methow Valley was relatively warmer, too.
Winthrop reached 100 degrees, up 1 degree from its previous 1925 record. Grand Coulee Dam came in at 103 degrees, up from the previous 99 degrees record, also set in 1925.
