The National Weather Service in Alaska issued a flood warning Monday morning for rivers in the Susitna basin, extending until Wednesday morning as heavy rains threaten to push water over banks.
"Heads up Susitna Valley!" the agency warned on its Facebook page.
"The greatest amounts of rain will likely occur along the west side of the Talkeetna Mountains and along the Denali Highway," the agency said. "Heavy rain will cause rivers to rise to bankfull or possibly exceed bankfull conditions."
More than 2 inches of rain is expected to fall in mountainous areas, with up to 2 inches expected in valleys, the agency said.
Rivers that could be affected are the Yentna, Skwenta, Maclaren, Montana, Willow and Little Susitna.
The agency advised people to check on the weather at weather.gov/anchorage.
