With temperatures as much as 33 degrees below normal, western Pennsylvania is swamped in ice and long overdue for a warm spell. When the weather breaks, so will the ice.
In some places we’ve already seen some flooding. On Tuesday February 24 The Weather Channel wrote:
In western Pennsylvania, flood warnings have been issued for Armstrong and Clarion counties due to an ice jam that is blocking the Allegheny River, creating a backflow of water into Parker, according to an AP report. The warning is in effect until 7 a.m. Thursday. State Route 268 has been flooded and at least two people have been rescued from the floodwaters in Parker.
In February 2009 I was hiking at Raccoon Creek Wildflower Reserve when the ice broke and jammed in front of me. Click here or on the gray-brown ice photo for my in-person (Throw Back Thursday) report.
