Temperatures in Clark County will likely reach 100 degrees this week, according to the National Weather Service. The agency’s Portland office has issued an excessive heat warning for the region starting at noon Thursday.
Temperatures will start rising Wednesday with highs of 90 to 95 degrees before rising to about 100 degrees Thursday afternoon.
“We’re definitely going to be heating up,” said Noah Alviz, meteorologist with the National Weather Service in Portland.
A high-pressure ridge is expected to settle over the Pacific Northwest, bringing high temperatures, Alviz said. Thursday and Friday will be the hottest days, with temperatures cooling off over the weekend. The warning will remain in place until 10 p.m. Friday.
The meteorologist said overnight lows in Clark County will struggle to get below 65 degrees Thursday.
“We may see some poor overnight relief from the heat during the day,” Alviz said.
The weather service advises people to drink plenty of fluids, stay in air-conditioned spaces, stay out of the sun, and check up on relatives and neighbors.
Cars’ interiors will reach lethal limits in minutes during such high temperatures, the weather service cautioned. Don’t leave young children and pets unattended in vehicles.
The weather service advised wearing lightweight and loose-fitting clothing when outside and limiting strenuous activity to early morning or evening.
The Occupational Safety and Health Administration recommends outdoor workers take frequent breaks in shade or air-conditioned environments. Anyone overcome by heat should move to a cool or shaded location.
“Heat stroke is an emergency,” the weather service’s heat warning stated. “Call 911.”
Daytime cooling centers will be open in Vancouver at St. Paul Lutheran Church, 1309 Franklin St.; Marshall Community Center, 1009 E. McLoughlin Blvd.; Water Resources Education Center, 4600 S.E. Columbia Way; and Firstenburg Community Center, 700 N.E. 136th Ave.

Temperatures will dip into the upper 80s and low 90s Saturday and low to mid-80s Sunday, Alviz said.
