The National Weather Service in Anchorage has issued a flood advisory for the Kenai River from Kenai Lake to Soldotna, effective until 4 p.m. Saturday.
According to the Weather Service, 2 to 3 inches of rain has fallen in the headwaters of the Kenai River. Rain is expected to taper by early Wednesday, but more is expected Thursday and Friday. The rainfall is expected to cause sections of the Kenai to reach bankfull or minor flood stages Thursday and Friday. River crests will be broad and sustained. Low lying areas close to the river will experience minor flooding.
The National Weather Service reports that the Kenai River at Cooper Landing is currently at 11.7 feet and is expected to crest at 12.3 feet Thursday afternoon. Bankfull stage is 12 feet and water is forecast to be at or above this level through Saturday.
The Kenai River below Skilak Lake is currently at 12.3 feet and is expected to crest at minor flood stage of 13.0 feet Thursday night.
The Kenai River at Kenai Keys is currently at 10.4 feet and is expected to crest at 11.2 feet Thursday night, which is just above the flood stage of 11.2 feet. At 10.8 feet, water will be over Dolly Way Road. If the river reaches 12 feet, water will begin to flow over roads in the Kenai Keys subdivision.
The Kenai River is not expected to reach bankfull stage in Soldotna.
Rain will cause considerable ponding of water in low lying areas, near culverts and along small creeks and drainages.
A flood advisory means river or stream flows are elevated or ponding of water in urban or other areas is occurring or is imminent.
