Extreme fire risk across most of Minnesota

(Fargo, ND) -- There's an extreme risk of wildfire across most of Minnesota.  

The National Weather Service has expanded Red Flag Warnings to cover the vast majority of the state.  

Experts say warm and dry weather conditions make it so even one spark can spread to an out-of-control wildfire.  

The Red Flag Warnings remain in effect through 8 p.m. Tuesday, though that's subject to change.
