Flood Warning for ice jam in effect for part of Armstrong County; snow showers develop tonight

PITTSBURGH — A Flood Warning for an ice jam is in effect until 9 p.m.

The National Weather Service Pittsburgh says the impacted area includes northern Armstrong County near the Wattersonville area and potentially downriver to Lock No. 8 along the Allegheny River.

“Flooding of rivers, creeks, streams and other low-lying and flood-prone locations is imminent or occurring,” the NWS says. “Depending on ice behavior, any release of the ice jam could result in sudden rises of water, leading to a rapid flooding situation.”

The NWS gave these precautionary and preparedness measures:

• Turn around, don`t drown when encountering flooded roads. Most flood deaths occur in vehicles.
• Be aware of your surroundings and do not drive on flooded roads.
• Flooding is occurring or is imminent. It is important to know where you are relative to streams, rivers, or creeks, which can become killers in heavy rains. Campers and hikers should avoid streams or creeks.
