Volume 2 — Issue 3 — April 2011 co n n e c t io n www.mesonet.org An estimated 2.5 million acres are burned annu-ally across Oklahoma, 10 percent by wildfire and 90 percent by prescribed burning. During multiple wildfire outbreaks in March, thousands of acres burned across the state. All 77 Oklahoma counties were placed in a state of emergency due to wildfires on March 11, 2011. Wildfire season typically begins during the drydown of vegetation in the fall and lasts until the greenup period in the spring. However, wildfires can occur anytime of year in Oklahoma. “The main factors contributing to wildfires are the amount and distribution of dead and live fuels, their moisture levels and weather factors,” said J. D. Carl-son, OK-FIRE program manager. When relative humidity drops below 35 percent and wind speed surpasses 20 mph, fire danger increases. As relative humidity drops and wind speed rises, fires become difficult to contain and can spread quickly. On March 11, 2011, 42 fires were reported statewide and more than 30 homes were destroyed, according to the Oklahoma Department of Emergency Manage-ment. “Relative humidity percentages in the mid-teens, com-bined with afternoon sustained winds of 20 to 30 mph and you had the setting for a major fire outbreak,” Carl-son said. The Mesonet’s OK-FIRE website is designed to help monitor and assess fire danger across Oklahoma. It features recent, current and forecast products for fire weather, fire danger and smoke dispersion. “We use OK-FIRE to support fire departments in the field during an incident and help the county commis-sioner monitor conditions that could lead to a burn UpF lIanmes ban,” said Lloyd Colston, Director of Altus Emergency Man-agement. To access OK-FIRE, visit www.mesonet.org and click the OK-FIRE button on the main page. This will direct you to the OK-FIRE website. “As grasses begin to turn green in April, fire danger will begin to subside,” Carlson said. “However, if the drought continues, we could see wildfires continue into the summer months.”
