High Temperatures Return to California This Week

As summer continues, triple digit temperatures remain possible across significant portions of the golden state through Wednesday.

As of 1400 on August 14th, the National Weather Services has active Heat Advisories for 27 counties and Excessive Heat Warnings for six counties. For an up-to-date list of counties affected by weather advisories, visit the NWS website.

According to NWS Western Region, Californians should be prepared for widespread, moderate to major heat risk through Wednesday of this week. Possible record breaking daily high temperatures and overnight warm low temperatures are possible across portions of central and northern California, with little overnight recovery. Fortunately, areas along the coast and at higher elevations will remain cool enough to limit to only Minor Heat Risk impacts and widespread cooler temperatures are expected Friday through the weekend.

Previously in California, during the month of July, 117 highest max temperature records were tied, and 241 highest max temperature records were broken, for a total of 358.

As high temperatures continue to threaten Californians, please be mindful of the health and safety of you and your loved ones.
