Red flag warning issued for high wind, low humidity
A red flag warning for severe fire danger due to gusty winds and low humidity is in effect for Western Nevada.
The warning goes into effect 2 p.m. Thursday and will last through 11 a.m. Friday, and will affect both the western valleys and the Sierra, according to the National Weather Service.
Strong south to southwest winds gusting up to 55 mph are possible in wind-prone areas of the Valley on Thursday night. Gusts of up to 85 mph are expected over the Sierra ridges.
Low pressure off the California coast will move into Oregon on Thursday night. Winds during the day on Thursday are expected to be 15-25 mph in the Valley, gusting to 35-40 mph.
Forecasters predict humidity will be 5-15 percent on Thursday and that it won’t increase much overnight, with some slopes and ridges in the Lake Tahoe basin may remain in single digits overnight.
The combination of gusty winds can result in new fires spreading rapidly.
