CALIFORNIA, USA — The National Weather Service in Reno has issued a Fire Weather Warning for areas north of Truckee to the Oregon border and into Nevada.
Unstable weather forming over the Sierra may cause the formation of thunderstorms. The concern lays with sparks torching grasslands that have been extremely dry, even through the spring.
Humidity levels could be as low as 7-16% for some areas and are ready to be large vegetation fuel for any fires that begin.
Winds may pick up because of these potential thunderstorms, causing occasional gusts. If a fire does start, those gusts would aid in moving the fire quickly; especially with the topography of the land being at a slope.
Sloping topography helps fires move upslope quickly and makes it harder for firefighters to contain.
Fire crews have responded to spot fires across the valley and foothills due to low humidity and winds 10-15 mph in the valley. Although a red flag warning or fire weather watch has not been issued, fire crews are on alert.
Several fires broke out Monday in North Sacramento and El Dorado Hills. Cal Fire contained the Blackstone Fire in El Dorado Hills to 90%. No structures were damaged or destroyed and no one was hurt while Cal Fire worked to contain the fire.
Metro Fire said in a tweet that a fire burned near 9000 Watt Avenue, which was near Gibson Ranch Regional Park and off of Baseline Road. That fire burned 71 acres, according to Metro Fire.
Cooler temperatures are expected this week in the mid 80s but won’t last long.
Triple digits are expected to return by the weekend and may continue into next week.
