The post further elaborated, saying, “Scott Van Dyken is on scene assessing the situation.” 

Van Dyken is the acting coordinator of the Cascade County Department of Emergency Services (DES).

The Cascade County DES website advises individuals at risk of flash flooding to “know your evacuation route;” “move furniture and belongings to upper floors;” and “keep materials like sandbags, plastic sheeting, plywood and lumber handy for emergency water proofing.”
