The health department issued the following statement regarding the wildfires burning in the region:

If visibility is less than 5 miles in smoke in your neighborhood due to a wildfire or controlled burn, smoke has reached levels that are unhealthy. If smoke is thick or becomes thick in your neighborhood you may want to remain indoors. This is especially true for those with heart disease, respiratory illnesses, the very young, and the elderly. Consider limiting outdoor activity when moderate to heavy smoke is present. Consider relocating temporarily if smoke is present indoors and is making you ill.

A RED FLAG WARNING is in effect for Douglas, Jefferson and Clear Creek counties until 8 p.m. indicating high fire danger.

Memorial Day is looking sunny and comfortable with highs in the mid to upper 70s. More stormy skies and cooler temperatures return by the middle of next week.
