Since a Red Flag Warning is rarely issued, many people are caught off guard about what it means.
A Red Flag Warning is issued when weather conditions become supportive for explosive fire growth. It is issued to prevent burning in a situation where a fire can easily get out of control. Three criteria have to be met when considering a Red Flag Warning, 1.) Sustatined winds just above the surface above 15 miles per hour. 2.) Relative humdity values below 25 percent. 3.) 10 hour fuel moisture below 8 percent. (10 hour fuels - stem diameter less than 1 inch).
This afternoon's forecast for the Interstate 75 corridor calls for southwest around 15 mph with gusts up to 30 mph, relative humidities between 20 and 25 percent, and 10 hour fuel moisture less than 8 percent.
The public should restrain from burning this afternoon to avoid potential wild fires.
