Flash Flood Watch Continues For Central, Northeast Colorado

A National Weather Service flash flood watch continues for many regions in central, north and northeast Colorado.

The weather alert will be in effect until 9 p.m. Saturday for more than a dozen cities, including Denver, Boulder, Arvada, Lakewood, Golden, Littleton and Castle Rock.

"The stronger storms will produce 1-2 inches of rainfall in less than one hour," the weather alert read.

"Flash flooding will be possible in urban and low lying areas."

If there's heavy rain in your area and flooding begins, stay away from creeks, drains, ditches ravines and culverts, and climb to higher ground. Don't walk or drive in flood waters, and follow emergency response orders, officials said.

Here's a breakdown of the National Weather Service Boulder office alerts:

• A flood watch is issued on days when flooding is more likely on a river or large creek. A flood watch means flooding in the area is more likely than on a normal day, but that flooding is not currently expected.
• A flood warning is issued when flooding is forecast or occurring. A flood warning means flooding is expected or has been reported at designated river forecast points.
• Flood advisories are issued for minor flooding on rivers and creeks.
• Areal flood warnings are issued for flooding on parts of rivers or large creeks not covered by designated river forecast points.

The agency created the Advanced Hydrologic Prediction Service monitoring system to monitor potential flooding along rivers and large creeks in Colorado.
