Good morning,

The National Weather Service (NWS) has issued a Red Flag Warning (RFW) for very low, single digit humidities. The RFW includes Fire Weather Zone 212, which is high elevation Boulder County.  Zones 239 and 215 are not a part of the RFW. However, because 212 includes Boulder County, there will be NO OPEN BURNING from 0000 hrs on Wednesday, 10/9, expiring at 2359 hours on Wednesday, 10/9 throughout the county. West winds 10-20 mph with gusts to 40 mph can be expected. This event is consistent with fall weather seen on the front range preceding a drop in pressure before an incoming winter storm. High winds can be expected before the precipitation occurs on Thursday.

Strong winds and very low relative humidity are expected across most of the northern Colorado mountains this afternoon and again on Wednesday afternoon. The worst conditions will be along and north of Interstate 70 today, and along and south of Interstate 70 on Wednesday.
