Another day of critical fire danger is on tap in Denver, the Interstate 25 corridor and the Eastern Plains on Wednesday, meteorologists said.

The National Weather Service in Boulder issued a Red Flag Warning from 10 a.m. to 6 p.m. Wednesday along the Front Range foothills, I-25 corridor and the adjacent plains due to the warm temperatures, dry conditions and winds that could gust to 55 mph.

“Avoid activities that will cause a spark!” the weather service warned.

That includes following any burn ban restrictions, avoiding open flames or sparks and properly discarding cigarettes, the weather service said.

The temperature is expected to reach 70 degrees in Denver under mostly sunny skies on Wednesday, the weather service said. That’s about 22 degrees warmer than the average high for Feb. 25 in the city, according to archive data.

Winds in Denver could gust as high as 47 degrees Wednesday, forecasters said.

Out at Denver International Airport, 40 flights were delayed and four were canceled as of 7 a.m. Wednesday.

Meanwhile, in Colorado’s mountains, moderate to heavy snowfall will be possible Wednesday, the weather service said, before tapering off overnight.

“Travel impacts are likely,” the weather service said. “Especially across the high mountain passes.”

Along the I-70 corridor, there could be moderate impacts between Idaho Springs and Silverthorne where the winter weather could create hazardous driving conditions, the weather service said.

Tonight in Denver, there’s a slight chance of rain before 11 p.m. Skies are expected to be partly cloudy and temperatures will dip to about 36 degrees, forecasters predict.

Meteorologists are calling for sunny skies, breezy conditions and temperatures in the low 60s in Denver on Thursday.
