The Relative Humidity and Winds map displays the current relative humidity at 1.5 m (5 ft), displayed in percent (%), at each Mesonet site, as well as the 10-m average wind conditions across Oklahoma. Relative humidity (RH) indicates the percentage of water vapor that the air is currently holding (with respect to its maximum holding capacity at the current temperature). RH is the most critical weather variable for fire behavior, as a lower relative humidity leads to lower dead fuel moisture, especially in the 1-hour and 10-hour fuels. The 10-m (33 ft) winds are represented by wind vectors (arrows) whose lengths are proportional to the wind speed and which point in the direction toward which the wind is blowing. This map is updated every 5 minutes.
