As of Monday evening, the Line Fire in San Bernardino County has grown to 25,813 acres and is threatening mountain communities near Lake Arrowhead and Big Bear.

Multiple evacuation orders are in place for nearby residents. Authorities warn that more than 38,000 structures, including homes and businesses, are still threatened. Some, 8,800 structures are in places under mandatory evacuation orders and another 29,200 structures are under warnings, according to a Monday evening update.

The fire broke out last Thursday and has been a challenge for firefighters because off a mixture of high temperatures, steep terrain and dense brush. It has also created its own weather, generating erratic winds that cast embers far and wide.

The concern going into Tuesday: stronger winds, which could increase spotting, which happens when embers ignite more spot fires.

Fire officials say "the fire could remain active overnight as vegetation remains critically dry."

Cooler weather is on the way, and temperatures should drop back down to around normal later in the week.

On Saturday, Gov. Gavin Newsom declared a state of emergency in San Bernardino County to secure federal assistance for firefighting efforts.

Fire creates its own weather conditions

Terrifyingly awesome pyrocumulonimbus clouds formed on Saturday and Sunday afternoons, generating erratic winds and lightning strikes which threaten new fire starts. There's a good chance they'll show up again on Monday, according to the National Weather Service in San Diego.

To form, the clouds need both a source of lift and a source of moisture. When the fire burns extremely hot, that hot air rises high into the atmosphere, carrying with it a whole lot of water released by live plants, primed to burn after months of extreme temperatures throughout Southern California.

The towering pyrocumulonimbus clouds can climb to 40,000 feet in the air.

A wildfire smoke advisory has been extended until Monday night as the smoky air will continue to impact San Bernardino, Riverside, Orange and Los Angeles counties. We have a guide on how to keep yourself safe from wildfire smoke.
