"Strong winds and low humidity today. Avoid any outdoor burning or activity (mowing, firearms, dragging chains, etc.) that may produce a spark and start a wildfire. Be ready to take action should a wildfire start," said the NWS.

9:35 a.m. | Red flag warning in effect | The I-25 corridor, including the Denver metro and northeastern Colorado are under a red flag warning until 6 p.m. Monday. This means high winds and low relative humidity are creating conditions for the rapid spread of any outdoor fire.

9:00 a.m. | Lisa's forecast | The winds will kick up even more across the metro area through early morning, with speeds between 20 to 40 mph and gusts closer to 60 mph. Some of the higher mountain peaks could see gusts up to 80 mph. It's a setup for blowing dust, downed branches, and definitely elevated fire danger.

A red flag warning is in effect from 9 a.m. to 6 p.m. for most of eastern Colorado.
