Wildfires - March 2012
NCEI added Alaska climate divisions to its nClimDiv dataset on Friday, March 6, 2015, coincident with the release of the February 2015 monthly monitoring report. For more information on this data, please visit the Alaska Climate Divisions FAQ.

During March, wildfire activity across the U.S. was below average, although warm and dry conditions occurred across a large portion of the country. The 89,771 acres which burned in March was the 2nd least in the period of record, and the 5,354 fires was the fourth least.

As a whole, the contiguous U.S. had its warmest March on record, with much-warmer-than-average temperatures across the eastern two-thirds of the country. Precipitation totals were mixed during March, with drier-than-average conditions across the inter-mountain West, parts of the Northern Plains, Ohio Valley, the Northeast, and Florida. Wetter-than-average conditions were observed across the Pacific Northwest and the Southern Plains. See the U.S. temperature and precipitation discussion for additional information. According to the U.S. Drought Monitor, the percent area of the contiguous U.S. experiencing Moderate-to-Exceptional Drought (D1-D4) shrank from 38.7 percent at the beginning of March to 36.8 percent at the beginning of April. During March, drought conditions deteriorated by one-to-two categories across the Southwest. Improvements of one drought category were observed across the Southern Plains which were wetter than average during March. Very little change in drought was observed across the Upper Midwest, with Severe Drought persisting across southern Minnesota and Iowa. Drought conditions also persisted across the Southeast, with a slight improvement of the Exceptional Drought across southern Georgia.
During the last week of March, the Lower North Fork Fire destroyed approximately 4,140 acres southwest of Denver, Colorado. The wildfire started on March 26th, when embers from a separate controlled burn ignited the fire. Extremely high winds and dry, abundant fuels caused the fire to grow rapidly out of control into populated areas. The rapid growth of the intense fire resulted in the fatalities of three citizens, destruction or damage to 25 homes and numerous outbuildings, and caused thousands of residents to evacuate the area. The fire was fully contained by April 2nd.

At the beginning March, there were there were 15 large wildfires active across the country. Ten of the wildfires were active across eastern Oklahoma, Missouri, and Arkansas, where moderately low 10-hour and 100-hour fuel moistures and high fire danger were observed. Two fires were burning across eastern Tennessee, where windy and dry conditions the last few days of February created ideal wildfire conditions. Two fires were burning across Florida, which has been particularly dry for the past several months, lowering fuel moistures and increasing the KBDI values across the state. One additional large wildfire was burning in South Dakota.
At the middle of March, there were 21 large fires burning across the country. Seven of the fires were burning across the Northern Plains of Nebraska, South Dakota, and Minnesota, where warm and dry conditions during the month increased fire danger and lowered 10-hour fuel moistures. There were five large wildfires burning across Texas and Arizona, where Severe Drought and high KBDI values were reported. Five fires were active across the Ohio Valley, where low 10-hour fuel moistures were observed
On March 30th, there were 13 large wildfires burning across the country. Three large fires were burning across the Southern Appalachians of Virginia and Tennessee, where moderately low 10-hour fuel moistures were observed. Four large wildfires were active across South Dakota and Nebraska, where low 1,000-hour fuel moistures were observed. Three fires were burning in Kansas and Missouri which was experiencing low 10-hour fuel moistures at the end of the month. One fire was burning in the panhandle of Florida, where high KBDI values were present. The last fire burning was the Lower North Fork Fire in Colorado, where low 10-hour and 100-hour fuel moistures combined with very strong winds to create high fire danger.
