yesterday`s rains.

Avoid burn areas and flood prone areas this weekend. Have multiple

take action and move to higher ground if you live in a flood
prone area, and never drive into flooded roads.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

The chance of showers and thunderstorms will decrease across the
plains and I-25 Corridor early next week with continued chances
over the mountains/foothills through mid-week. There will still be
heavy rainfall possible along with the threat of flash flooding
in the burn areas.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight, but
rainfall reports or any reports of flooding would be greatly
appreciated.
