September started off extremely hot, as high pressure built over the area. This led to unseasonably hot temperatures for most of northern California with widespread triple digit heat forecast, accompanied by little overnight relief for the Labor Day weekend. Between September 5 and September 8, one county in the Sacramento Valley recorded five heat related visits to the emergency room; however, as of this time, no deaths were reported. On the tail of this heat wave, critical fire weather conditions occurred due to a trough sliding into the Great Basin area. Gusty winds led to 83 reports of wind related damage or hazards to a utility company across all of northern California, including areas served by NWS Eureka and NWS Monterey. Damage locations in the events are estimated by the map provided to the public. Gusty winds also wreaked havoc on the North Complex.
