UPDATED - This article has been updated to reflect increased fire danger for Tuesday

The National Weather Service Offices in Pueblo, Goodland and Boulder have issued a Red Flag Warning for all of eastern Colorado Tuesday due to the extreme fire danger.

Cooler temperatures Sunday were replaced with highs in the low to mid-80s Monday, along with drier air.

Highs increase further Tuesday to near 90, or as much as 10 degrees above seasonal norms. Gusty winds are expected to develop Tuesday afternoon, increasing the fire danger. Wind will be out of the southwest at 15 to 20 miles per hour, with gusts between 40 and 50 mph possible. The strongest gusts are expected in higher elevations. Humidity will drop to 10 percent or less, creating conditions favorable for fires to grow rapidly.

The warning will be in effect from 11:00 a.m. to 8:00 p.m. Tuesday.

Currently, the warning extends east from the Colorado-Kansas border to the east-facing mountains. Some of the northeast Colorado counties were under a fire weather watch, how this areas were also added to the warning over night.

Temperatures are expected to drop into the 70s Wednesday as cooler air drops into the area.
