Six structures have been destroyed and two others have been damaged. Meanwhile, 1,560 structures remain threatened. At least four firefighters have suffered minor injuries.

The agency said in its Wednesday morning update that mountainous, steep terrain has been a challenge, along with the absence of a marine layer due to the ongoing heat wave in the region. Monterey County remains under an Excessive Heat Warning through Wednesday night, according to the National Weather Service.

Poor air quality is also an issue. According to data, particulate matter pollution has reached very unhealthy and hazardous levels on the Monterey Peninsula as of 9 a.m., including the communities of Monterey, Seaside, Carmel and the Carmel Valley.
