Three fires near the border between Kansas and Oklahoma are being managed as the NW Oklahoma Complex of Fires, comprised of the Starbuck, 283, and Selman Fires. The Starbuck fire, by far the largest, began east of of Beaver, Oklahoma and ran to the northeast into Oklahoma. The city of Ashland, 40 miles away, had to be evacuated and was later surrounded by the fire.
George Geissler, the Director of Oklahoma Forestry Services, announced on Wednesday that together these three fires have burned over 833,941 acres.
The wildfires that grew to blacken hundreds of thousands of acres continue to grow larger in Kansas, Texas, and Oklahoma on Tuesday.
In the map below the red dots represent wildfire heat detected by a satellite at 12:57 p.m. CST March 7, 2017. The white line was the very rough, approximate perimeter we developed from heat detected by satellites on Monday. The fires are still growing on Tuesday, spreading toward the southeast, pushed by strong west and northwest winds gusting at 20 to 40 mph. The relative humidity in the western two-thirds of Kansas has fallen Wednesday to the single digits.
The towns of Protection and Coldwater in Kansas are threatened.
There are reports that five civilians, not firefighters, have been killed in wildfires in recent days in Texas and Kansas.
In Gray County, Texas, approximately 60 to 80 miles east of panhandle city of Amarillo, three ranch hands were killed as they were moving cattle out ahead of a fire, according to Judge Richard Peet. In Texas county judges are responsible for suppression of wildfires.
Another person was killed in Hemphill County, Texas near Oklahoma border.
The Kansas Highway Patrol says 39-year-old Corey Holt, of Oklahoma City, jackknifed Monday while trying to back up his tractor-trailer on highway 34 in Clark County due to poor visibility from the fires. He was killed after he got out of his vehicle.

On Monday a cold front brought very strong winds to the plains of Kansas and the northern portions of Texas and Oklahoma. Gusting in some areas at over 50 mph and accompanied by low relative humidities, any wildfires that were ignited spread very rapidly, and often exceeded the capabilities of firefighters.
The largest fire started east of Beaver, Oklahoma and ran to the northeast into Oklahoma. Ashland, 40 miles away, had to be evacuated. It is not 100 percent clear if the fire in Ashland was the same fire that started in Oklahoma, but it likely was.
After the cold front passed, the southwest wind shifted 90 degrees to come out of the northwest, which converted the right flank of the fire into the head as it turned and ran to the southeast.
The fire burned in the following counties: in Oklahoma, Beaver and Harper; in Kansas, Meade, Comanche, Clark, and possibly Ford. As of 3:16 a.m. CST satellite data, the fire was still very active in some areas.
The map below shows heat detected by a satellite in the 24 hours before 11:30 a.m. CST March 7, 2017. We drew a red-tinted polygon around the heat icons for the fire east of Beaver. The satellite only collects data twice a day at roughly 12-hour intervals. As the fire spreads rapidly through mostly grass with the strong wind, it can cool and not be detected by the next satellite overflight. We don’t know if everything within our red polygon was all one fire, and even if it is there likely are many areas, some large, that did not burn. So with all those disclaimers, the red polygon includes about 600,000 acres.
The red polygon we drew around the wildfire east of Laverne, OK encompases about 30,000 acres, but the same disclaimers about the fire east of Beaver also apply here.

Below is an updated map showing growth of some of the fires in Kansas, especially the one 17 miles southeast of Meade, Kansas that burned from Oklahoma into the state. That one, using very rough satellite data, appears to be more than 130,000 acres.
There was a report, as yet unconfirmed, that in Kansas a tornado moved over a going fire.

Strong winds along with relative humidities in the teens and twenties are causing problems for firefighters in the western half of Kansas. The passage of a cold front is bringing sustained wind speeds of 30 to 40 mph with maximum gusts in the 40’s and 50’s.
On the map above we identified and very roughly mapped four of the largest fires. The acreages shown are estimates based on satellite detections of heat at about 1 p.m. MST on Monday. One of them has burned from Oklahoma into Kansas.
53,000 acres; 17 miles southeast of Meade, Kansas. It is in Meade and Beaver Counties in Kansas, and Clark County in Oklahoma.
6,500 acres; in Clark County 23 miles east of Meade, Kansas.
7,000 acres; in Lane County Kansas 10 miles southeast of Dighton, Kansas.
4,000 acres; in Rooks County Kansas just southwest of Stockton, Kansas. Residents in part of the city have been ordered to evacuate.
A fire in Logan County in the northeast corner of Colorado has burned 6,000 acres 20 miles northeast of Sterling.
Before the cold front passed the fires were driven by a southwest wind (see the animated radar map below). As the front passes the wind is shifting 90 degrees to come out of the northwest. This could be a very, VERY dangerous situation for firefighters on the south side of the fires, as the right flank turns into the head of the fire.
In February we posted some statistics showing that historically there is a large spike in wildfire activity in March and April in Kansas. The spring is also a time when many, many ranchers conduct prescribed fires in the Flint Hills of Kansas and Oklahoma. This year between February 27 and May 5, 2.7 million acres were treated with prescribed fire.
Referring to the bar graph below, and throwing out the two busiest and the two slowest data points, in a typical year land managers in the Flint Hills burn between 1.1 million and 2.8 million acres.
