Fire danger in Denver remained extremely elevated Wednesday and meteorologists issued a Red Flag Warning again to warn residents of the risks.

The National Weather Service in Boulder issued the warning and said it was in effect from noon to 8 p.m. Wednesday due to high temperatures, gusty winds and dry conditions. The Red Flag Warning area includes the Denver metro area along the Interstate 25 corridor between about Loveland and Castle Rock and east across most of the plains.

“Conditions will be favorable for rapid fire spread in areas that have not received significant recent precipitation,” the weather service said in its warning. “Avoid outdoor burning and any activity that may produce a spark and start a wildfire.”

Residents were advised to follow burn ban restriction and to avoid driving on grass and to properly discard of cigarettes.

Meteorologists said the temperature in Denver was expected to reach 88 degrees on Wednesday. That’s about 6 degrees hotter than the normal high for June 10 in Denver, according to weather service archive data. The record high for this date is 99 set in 2013.

Wind in Denver is expected to blow at 12-17 mph out of the west Wednesday afternoon, with gusts up to 29 mph, the weather service said. The winds will be strongest along the Wyoming border, where gusts of 30-40 mph are possible.

Couple that with the 11% relative humidity and it’s a recipe for a fast-spreading wildfire, the weather service said.

The weather service said there’s also a minor heat risk across the Denver metro area on Wednesday, but it will primarily impact people who are extremely sensitive to heat and don’t have access to adequate cooling or hydration.

Temperatures are expected to dip to 53 degrees overnight in Denver before heating back up to a high of 78 on Thursday, meteorologists said.
