Wildfires have left 4,254 energy customers without power as of this morning, according to the energy-tracking website PowerOutage.us.

This includes almost 2,000 customers in Hutchinson County, where the Smokehouse Fire has already covered more than 300,000 acres.

A sheriff's office working to evacuate people from fire-threatened homes in a neighboring county said the "Panhandle needs prayers," as fires continued to spread.

The Moore County Sheriff's Office has been dealing with calls related to a 40,000-acre fire at Windy Deuce in Moore County, which is 20% contained, and is assisting deputies from Hutchinson County, where the huge Smokehouse Creek Fire has already covered 300,000 acres.

"We have seen tragedy today and we have seen miracles. Today was a historic event we hope never happens again," the office said in a Facebook post.  

Firefighters were battling at least five wildfires in the Texas Panhandle, which have already burned through almost 400,000 acres, according to the Texas A&M Forest Incident Viewer.

The biggest, at Smokehouse Creek in Hutchinson County, has grown to 300,000 acres, more than 450 square miles, and is zero percent contained. According to A&M data, it is the fifth-biggest wildfire in Texas history.

At least four fires, including one near Amarillo, have now been contained.

Authorities in several locations across northern Texas have told people to leave their homes as uncontrolled fires continue to spread.

The National Weather Service in Amarillo said last night that a mandatory evacuation order was in place for the Mesilla Park area of Potter County.

The Moore County Sheriff's Office said Double Diamond, an area west of the city of Fritch, was subject to an emergency evacuation alert.

"Due to an the approaching fire it's imperative to evacuate the area for your safety and well-being," the office said in a statement. A shelter has been opened at Celebration Family Church, 811 E, Broadway, Fritch.

The Hemphill County Hospital District said it had moved all patients and residents from its hospital and nursing homes in the city of Canadian, to facilities in Pampa to the southwest.

Evacuations have been ordered and Texas Gov. Greg Abbott issued a disaster declaration for 60 counties as wildfires burn in parts of the panhandle.
