Red Flag Fire Warnings for 11 Western States

The National Weather Service (NWS) issued a Red Flag Warning in 11 states on Friday as conditions are ideal for wildfires.

According to an NWS map, almost all of Wyoming is under a red flag, as are much of Idaho, South Dakota, Oregon, Nevada, Utah and Nebraska. The same warning has now been issued for small parts of Northern California, southern Montana, northern Colorado and eastern Washington.

“A red flag warning is issued when we detect weather conditions that are conducive to the rapid spread of a fire that can become life-threatening. That doesn’t mean there’s a fire. These conditions are either occurring now or will begin soon,” the NWS states in a statement posted on its website.

Many of these red flag warnings are only in effect until this evening when conditions are less than ideal for a fire to develop. However, warnings are expected to remain in place through Saturday afternoon in several regions in Montana, Wyoming, Nebraska and South Dakota.

The NWS issues red flag warnings to warn people of critical fire weather conditions that increase the risk of wildfires starting and spreading quickly. These warnings are usually based on a combination of factors such as low humidity, high winds, dry vegetation and warm temperatures.

When humidity falls below a certain threshold, fires can start more easily, while strong winds can fan flames and cause fires to spread quickly. Additionally, warm conditions or a prolonged period without rain can dry out vegetation, providing ample fuel for fires – dry grasses, trees and shrubs ignite easily and burn quickly.

“Winds will increase as a Pacific cold front sweeps across the Pacific Northwest. Parts of central and eastern Oregon and southeastern Washington will experience very dry air and breezy winds ahead of the frontal passage this afternoon. Therefore, this area will be vulnerable “The fire spread quickly,” the NWS office for Pendleton, Oregon, said Friday morning.

Similar low humidity and strong winds are driving fire-prone conditions across warning states, with parts of Colorado potentially seeing record-breaking temperatures this time of year.

“Gusty west-southwesterly winds will develop over higher ground on Friday afternoon. The strongest winds will be in Jackson County and far northwest Larimer County, with gusts up to 30 mph. Additionally, relative humidity is expected to fall into the low teens,” NWS said Denver/Boulder CO. “Gusty westerly to northwesterly winds will spread across much of north-central and northeastern Colorado on Saturday. Temperatures will be very warm (possibly record-breaking), resulting in relative humidities of 10 to 14 percent.”

This is because large parts of California are suffering from unusually high temperatures. The NWS has issued multiple “Heat Warnings” and “Overheat Warnings” throughout Central and Southern California, with temperatures as high as 114 degrees predicted in some areas.
