Fire weather hazards will be present through the weekend. On Friday afternoon and evening, a combination of gusty winds and low humidity could enhance fire behavior in parts of Klamath, Lake, Modoc, and eastern Siskiyou counties. On the afternoon and evening of Saturday and Sunday, isolated to scattered thunderstorm activity will produce lightning on dry fuels, and could cause new wildfires.
Impactful daytime highs and warm nighttime lows continue to pose health risks through Saturday. An Excessive Heat Warning remains in place for central and western Siskiyou County, with highs between 100 and 105 degrees and lows of 65 to 70 degrees. A Heat Advisory will cover the Rogue, Applegate, and Illinois valleys as well as areas east of the Cascades. Highs for the listed west side valleys will also be between 100 and 105 degrees, these areas will have better nighttime cooling, with lows between 55 and 65 degrees. East of the Cascades, highs will be 95 to 100 degrees, with lows between 50 and 65 degrees in most areas (40 to 50 degrees in the Chemult/Crescent area).
Here are some helpful tips and steps to protect yourself and others from this heatwave.
Planning to cool off in area lakes and rivers? Remember the waters remain cold and drowning from cold water shock is real. Always wear a life jacket when swimming and boating.
