More Winds and Low Relative Humidity Expected; National Weather Service Issues Red Flag Warning, Given Critical Fire Conditions

It’s October and last night’s temperatures, dropping into the 20s, suggest that we are officially into the fall season. Earlier this week, the National Weather Service had issued a Wind Advisory and a Fire Weather Watch; today, a Red Flag Warning is in effect for the San Bernardino mountains, prompted by low relative humidity and northeast winds of 15 to 25 miles per hour, with gusts up to 35 miles per hour—gusts between 40 and 50 miles per hour are possible in the most wind-prone areas. These factors produce critical fire weather conditions, which, per the National Weather Service, are likely through this evening under the Red Flag Warning.
