Seasonable Temperatures Next Week

After 100-degree heat took hold over central California the last few weeks, more seasonable temperatures are expected beginning this weekend. Widespread Minor Heat Risk will develop, which is heat tolerated by most of the population, but can cause heat-related illnesses to those extremely sensitive to heat such as older adults (65+), infants, those without effective cooling, and those with chronic diseases (heart disease, obesity, poor blood circulation).
