POOR HUMIDITY RECOVERIES ARE EXPECTED SUNDAY NIGHT AND MONDAY NIGHT ACROSS THE FOOTHILLS AND WIND EXPOSED LOCATIONS. THE COMBINATION OF GUSTY NORTHEAST WINDS, VERY LOW HUMIDITIES, VERY WARM TEMPERATURES AND CRITICALLY DRY FUELS HAS PROMPTED THE WATCHES AND WARNINGS.

“It’s quite dry in the mountains as far as the fuels are concerned. They are in critical condition,” Balfour said. “The relative humidity right now in the mountains is already below 15%, but we don’t have the winds blowing yet.” - Robert Balfour, a senior forecaster for the National Weather Service in San Diego

  
A RED FLAG WARNING MEANS THAT CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED. THIS IN COMBINATION WITH VERY DRY FUELS COULD CREATE EXTREME FIRE DANGER AND/OR FIRE BEHAVIOR. PLEASE ADVISE THE APPROPRIATE OFFICIALS OR FIRE CREWS IN THE FIELD OF THIS RED FLAG WARNING.

Growing numbers of communities, across the nation, are experiencing longer fire seasons; more frequent, bigger, and more severe, fires are a real threat. Be careful with all campfires and equipment.
