The National Weather Service in Reno has issued a fire weather watch for much of western Nevada and northeastern California, in effect from Friday morning through Saturday evening.
The watch is prompted by forecasts of gusty winds and low humidity levels that could lead to rapid fire growth.
In an X post, the National Weather Service warned of a moderate risk, or 3 out of 5, for critical fire weather conditions in the region.
Wind gusts are expected to reach 35 to 40 mph, with afternoon relative humidity ranging from five to 15 percent.
The fire weather watch includes several fire weather zones:
-
Zone 270: Surprise Valley, California
-
Zone 278: Eastern Lassen County
-
Zone 458: Northern Washoe County
-
Zone 420: Northern Sierra Front including Carson City, Douglas, Storey, Southern Washoe, Western Lyon and Far Southern Lassen Counties
-
Zone 423: West Humboldt Basin in Pershing County
-
Zone 429: Lahontan Basin including Churchill and Eastern Mineral Counties
Winds in the affected areas are expected to range from 15 to 25 mph with gusts up to 40 mph.
Minimum afternoon humidity could fall as low as 5 percent, with limited recovery overnight between 20 and 50 percent.
According to the alert, “The combination of gusty winds and low humidity can cause fire to rapidly grow in size and intensity before first responders can contain them. These dry and windy conditions could also rekindle fires in areas which received lightning in recent days.”
The weather service also noted that dry conditions and shorter periods of gusty winds today and Thursday could produce elevated to locally critical fire weather conditions.
Residents are urged to avoid outdoor activities that could cause sparks near dry vegetation, including yard work, target shooting, or campfires.
