How to resolve AdBlock issue? The agency said the red flag warning is in effect from 11 a.m. Sunday to 5 p.m. Tuesday.
A red flag warning means that critical fire weather conditions are either occurring now or will shortly, according to the National Weather Service, which also reported that a combination of strong winds, low relative humidity and warm temperatures can contribute to extreme fire behavior.
In the case of this latest warning, the National Weather Service said the highest threat across Northern California is in southern Lake County, the northern and western Sacramento Valley, and the adjacent foothills.
A combination of wind, low afternoon humidity and poor overnight recovery may create a period of increased fire starts or rapid spread through early Tuesday morning, according to the forecast.
The regional forecast calls for a gusty north to northeasterly wind to begin across the Coastal Range, northern and western Central Valley Sunday and spread across the Sierra Nevada Sunday night.
The wind is expected to range between 15 and 30 miles per hours, with gusts of up to 40 miles per hour in some parts of Northern California.
The specific Lake County forecast calls for light winds to actually begin on Saturday, with speeds ranging from the mid-teens in Lucerne and Lakeport into the mid-20s in the south county and Clearlake.
On Sunday night, wind gusts could range up close to 30 miles per hour on the Northshore and nearly 40 miles per hour in Middletown before tapering off on Monday, according to the forecast.
Temperatures in the coming week are forecast to range into the low 80s during the day and the low 40s at night.
