Daily record high temperatures are possible this week in the Mt. Shasta area, according to a Heat Advisory issued by the National Weather Service in Medford, Ore.

High temperatures are forecast to reach 98 to 108 degrees in western, central and south central Siskiyou County, with the lowest high temperatures near Mount Shasta City and the highest temperature near Somes Bar.

Low temperatures are forecast from 60 to 70 degrees.

The very hot daytime temperatures and limited relief overnight will increase chances for heat related illness, according to NWS, especially for sensitive groups and people without access to air conditioning. Heat stress is also possible for livestock and outdoor pets.

NWS states that “a very hot air mass, even for late July standards, will affect the forecast area,” bringing temperatures 5 to 10 degrees above normal for several days. “Additionally, smoke will exacerbate any heat related issues for vulnerable populations.”

The advisory is in effect from 11 a.m. Monday to 11 p.m. Wednesday, but NWS says there is potential for the heat wave to last until the end of the week.

It’s suggested that you drink plenty of fluids, stay in an air-conditioned room if possible, stay out of the sun, and check up on relatives and neighbors.
