The National Weather Service (NWS) says a combination of very low humidity in the air, couple with gusty winds and high temps, will make the possibility of fire high through early Tuesday. We hear it so much, but what exactly is a Red Flag Warning?

A Red Flag fire warning means this, according to the NWS:

"A Red Flag Warning means that critical fire weather conditions
are either occurring now....or will shortly. A combination of
strong winds...low relative humidity...and warm temperatures can
contribute to extreme fire behavior."
"A dry cold front pushing east of the Cascades this afternoon will
cause winds to increase. Afternoon and evening humidity values
will be be in the teens over much of the region. The combination
of gusty winds and low humidity values will create dangerous fire
weather conditions in the areas under a Red Flag Warning."

The Red Flag warning is expected to last until at least 9pm Monday night.
