'Dangerously hot' temps to spur Oregon wildfire growth

PORTLAND, Ore. (KOIN) — “Dangerously hot” daytime temperatures in the high 90s and low 100s are forecast for areas of Central and Eastern Oregon between Aug. 1 and Aug. 7, increasing the risk of heat-related illness and rapid wildfire spread, the National Weather Service and firefighting officials warn.

The National Weather Service has issued an excessive heat warning for Harney, Malheur, Baker and Wallowa Counties, and for northern central Oregon, from 11 a.m. Thursday to 8 p.m. Friday.

Public information officers for multiple wildfires burning in Eastern Oregon told KOIN 6 News that the 100-degree heat can dry out brush and cause wildfires to spread at a faster pace.

“When temperatures rise, our primary concern is that the fire may flare up and throw embers outside the fire line,” Battle Mountain Complex PIO Bryan Longoria said. “In anticipation of the coming warming trend, firefighters on the Battle Mountain Complex have been taking advantage of the milder weather to tie together control lines and increase mop-up depth along the perimeter and around structures.”

Temperatures could surpass 106 degrees in northeast Oregon and Southeast Washington, according to the latest forecasts.

The NWS recommends that people limit outdoor activities and stay cool and drink water regularly on 90 and 100-degree days.
