The Bobcat Fire in the Angeles National Forest continues to grow in its 14th day and authorities are ordering anyone in mandatory evacuation zones to leave immediately.

The fire has grown aggressively in recent days. By this morning, more than 93,000 acres had burned. The rapid spread was driven by wind gusts of up to 44 mph that pushed the flames into the Antelope Valley.

At the same time fire officials issued new evacuation orders, they said others would be lifted. At 4 p.m., residents living in areas currently under mandatory evacuation in Arcadia, Sierra Madre, Monrovia, Duarte, and Bradbury were be allowed to return home.

The focus today has been on the northern side of the fire. In the morning update, officials said the fire "has spread north into foothills communities of Juniper Hills and Valyermo." They also warned that the fire was just miles from the communities of Big Pines and Wrightwood

At a news conference last night, L.A. County Fire Chief Daryl Osby noted that many fires this year, including the Bobcat, have been very dangerous:

"The fire behavior that we're getting in this fire and throughout the state of California is unprecedented. It's very important that when your local law enforcement comes through or your local firefighters come through, please make sure that you evacuate."

Evacuation orders are in place for parts of the Antelope Valley and northern Angeles National Forest.

The National Weather Service continues to report "elevated fire weather conditions," adding wind gusts this afternoon into evening could reach 25 to 35 mph — and get above 40 mph in the foothills.

Here's what else we know about the fire so far today.

"Residents in these areas should quickly gather their families and pets and head to your preplanned location outside of the fire evacuation zones," forest officials wrote on the fire incident page. "Residents must take these necessary steps to ensure your family’s safety. Delaying evacuation will prevent fire crews from suppression activities and compromise the safety of the public and first responders."

The Mt. Wilson Observatory houses 18 telescopes, many of which were used to make some of the greatest astronomical discoveries of the last century. They include the 100 inch Hooker telescope that Edwin Hubble used in the 1920s to prove that our universe is still expanding.

Crews have been prepping structures near Mount Wilson. Retardant is also being placed around it.

Observatory Director Tom Meneghini said he's afraid they could be seriously impacted if the fire gets close enough.

"The heat can do irreparable damage. Our two big telescopes are historically significant and irreplaceable,” Meneghini said.

However, he said fires have gotten close before and the decades-old firefighting setup at the Observatory is ready to be used again. "We have an inground system of hoses and pumps," he said.

"We have half a million gallons of water ready to pump so that’s all been prepared for any fire professional to come in and take over."

The fire also threatens a seismic station that has recorded earthquake activity for 100 years, seismologist Lucy Jones said via Twitter.

Numerous television and radio stations have transmitters in the area, including our newsroom which broadcasts on the radio at 89.3 KPCC.
