River Watch aerial reconnaissance noted water has already started inundating surrounding low-level areas near the community. Aerial reconnaissance also noted that there are several spots of open water in the upper portion of the Kuskokuak Channel, as well as downstream beyond the Y. Until the ice shifts or moves, residents should prepare for continued rising water levels, particularly in flood-prone lower areas. Akiak and Tuluksak: Original ice still in place which may cause flooding as the breakup front moves downstream from Kalskag. Ice jams have been observed at/near Tuluksak, a few around Akiak, and near Bethel, with a decaying jam near Napaskiak downriver. Almost no intact-original ice is in place above Bethel, with a mix of broken sheets. - Http://www.weather.gov/safety/flood Information: Monitor the latest forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.

ESFAFG ...Locations Impacted... Tanana, Ruby, and Galena As of Monday evening the Yukon River breakup was located about 60 miles below Tanana. A long stretch of heavy, bank to bank ice run was noted from the breakup front to 20 miles upstream of Tanana. The river through this stretch was moving steadily with water levels remaining within the banks. Downstream from the breakup front, numerous large pressure ridges and shifted ice were observed to Ruby. Ice in front of Ruby shifted Monday morning and the tripod at Galena moved a few hundred feet downstream at Galena Monday. Meanwhile downstream of Galena at Bishop Rock the upstream side of the ice remained fairly strong and intact, while open water was present downstream. The River Watch team will fly this section of the Yukon Tuesday and an update is expected later Tuesday or early Wednesday. |
