Another heat advisory remained in effect Monday in the Sacramento region, but forecasters expect the weather in Northern California to gradually cool down over the next several days.
The risk of heat-related illness was characterized as “moderate to major” again on Monday throughout Northern California with officials urging residents to stay hydrated and in a cool place during the warmest times of the day, according to the National Weather Service in Sacramento.
Those working outside were cautioned to take plenty of breaks and find shade. This level of heat affects most people sensitive to heat, especially those without effective cooling and adequate hydration, according to the weather service. Residents were urged to reduce time in the sun between 10 a.m. and 6 p.m.
High temperatures throughout the region were expected to be in the upper 90s to triple-digits, so a heat advisory will remain in effect through 11 p.m. Monday.
The heat advisory issued by the weather service included the southern and central Sacramento Valley, the Northern San Joaquin Valley, the Delta and the adjacent foothills. The advisory stretched from Stanislaus County, including Modesto, to Chico in Butte County.
