The trend of record heat in Northern California is likely to continue Friday as a heat wave continues to challenge a region already vulnerable to wildfires. KCRA 3 is calling Friday an Alert Day because of both the dangerous heat that could lead to health issues and the high fire risks. Alert Days are issued when safety is a concern due to weather conditions. We have issued Alert Days since Tuesday and expect it to last through Sunday. Source: Police frequency
