Low humidity and high winds in Colorado’s mountains and foothills bring red flag warnings and fire danger to the state’s western side Saturday while severe storms continue over the Eastern Plains. “A red flag warning means warm temperatures, very low humidities and stronger winds are expected to combine to produce an increased risk of fire danger,” according to National Weather Service fire officials. NWS officials issued a red flag warning for northwestern Colorado on Saturday — especially around Dinosaur National Monument, White River and the Colorado River Basin.
