Most of Alaska has just come off of a colder or snowier (or both) winter than in recent years. Crane Johnson with the NWS Alaska-Pacific River Forecast Center will review break-up basics and an overview of current conditions. ACCAP Alaska Climate Specialist Rick Thoman will provide the latest subseasonal outlooks that help inform the APRFC’s official break-up outlook. Claude Denver, with the SEOC will provide an overview of the River Watch program, and provide information about planning for floods. Trisha Bower also joined us from the DEC Solid Waste Program to share best practices when protecting landfills and garbage during a flood. 

If your community experiences a flood and requires assistance from the State of Alaska, please contact the State Emergency Operations Center.
