In addition, a dry cold front will cross the region from northwest to southeast between 2 PM and 8 PM Monday, resulting in a sudden wind shift from south to northwest and an increase in wind gusts. In this environment, any new fires could spread rapidly and be difficult to control. PRECAUTIONARY/PREPAREDNESS ACTIONS... A Red Flag Warning means that critical fire weather conditions are either occurring now, or will shortly. A combination of strong winds, low relative humidity, and warm temperatures can contribute to extreme fire behavior. &&
