Flooding along the Green, Sevier and Colorado rivers in Utah may become a reality if record-breaking cold temperatures continue.
William J. Alder, meteorologist in charge of the U.S. Weather Service's Salt Lake office, said hydrologists are concerned over recent reports that ice floes are beginning to appear in the three rivers."Once ice chunks start forming, the potential for blockage or jamming becomes a possibility," Alder said. "Fortunately the rivers are not running high right now so that is a factor in our favor."
Idaho has recently reported flooding problems on the Portneuf River caused by ice jams.
Alder said Weather Service hydrologists are also keeping an eye on the Weber, Bear and Provo rivers but believe ice forming there is a remote possibility at this time.
"If the water keeps moving well, there is less likelihood that freezing will occur," Alder said.
