The National Weather Service, Spokane, has upgraded the fire weather watch issued this morning for an area including Boundary County and North Idaho, to a red flag warning in effect from 11 a.m. until 7 p.m. Sunday.
A dry cold front will sweep through the region Sunday delivering strong, consistent winds and very dry conditions. Winds will increase Sunday morning and remain strong through the afternoon. The air mass will be very dry so despite temperatures in the 60s and 70s, humidity levels will dip into the teens to mid twenties.
New and ongoing fires have the potential to spread rapidly. Additionally, it has been 30 to 60 days since the last wetting rain in portions of Central and Eastern Washington.
A Fire Weather Watch means that critical fire weather conditions are forecast to occur. Listen for later forecasts and possible Red Flag Warnings.
