A handful of fires burning east of Humboldt spread aggressively over the weekend, pushed by winds and dry fuel loads, and continue to bring air quality and travel impacts as far west as the coast, with State Route 299 still closed in Trinity County and no timetable for reopening. Air quality has improved markedly for the time being, though, though hot, dry conditions and wind gusts are expected to continue to complicate fire suppression efforts.

Here's a brief look at each and what you need to know.

The Fires

The Monument Fire, 97,287 acre
s, 10 percent contained
Located a half mile west of Big Bar along State Route 299 east of Willow Creek, the Monument Fire was sparked by lightning July 30 and grew more than 20,000 acres over the weekend to 97,287 acres with 10 percent containment. Evacuation orders remain in effect for Junction City, Red Hill, Canyon Creek, Coopers Bar, Big Bar, Del Loma, Big Flat, Helena, Cedar Flat and Burnt Ranch. For information on evacuation sites and animal shelters visit the Trinity County Sheriff's Office Facebook page here. "Last night, the Monument Fire was extremely active on all flanks, predominantly to the southeast," a morning update states. "The fire exhibited long, uphill runs and group torching as it advanced toward Sky Ranch Road in Junction City, prompting the evacuation order issued by the Trinity County Sheriff. ... Yesterday, the fire also made an uphill run toward the Ironside Lookout on the northwest portion east of the Trinity River. Embers ignited receptive fuels, destroying the lookout and communication infrastructure for the Shasta-Trinity National Forest and a repeater site for the incident." Gusty afternoon and evening winds of up to 25 mph are expected along the ridge lines and up the Trinity River Canyon. For more information, read about incident commanders' briefing on Wednesday with Congressmember Jared Huffman here, check the incident website here and a map of the fire's footprint here.

The McFarland Fire, 51,909 acres, 68 percent contained
Sparked by lightning July 29 on McFarland Ridge south of State Route 36, the fire is burning in timberlands with fuels with historically low moisture levels in an area that hasn't burned in more than 50 years. The fire grow by more than 10,000 acres over the weekend, though crews managed to increase containment to 68 percent. "Yesterday, gusty and dry west to northwest winds surfaced over the fire area and increased fire activity," the morning updates states. "Extreme fire behavior pushed the fire to the east into Beegum Peak and over Tedoc Mountain. ... The northwest section of the fire area remained relatively calm after mop-up efforts." An evacuation order has been issued from 1 mile north of State Route 36 from Platina to Vestal Road, for all homes south of State Route 36, including all of Tedoc Road, east to and including all of Vestal Road, north of Pettyjohn Road.
