Pro tip for people moving north; don't buy land in the valleys around Mt. Rainier. This type of flood (also known as a lahar) has occurred there many times. The mudflows reached the harbor of Tacoma in the past. [0] I expect we'll see at least one new one in our lifetime, as the glaciers have been greatly affected by rising temperatures.

Do you have a source about the Nepalese flood being a Lahar? I've only read that it was caused due to the glacier collapse, which seems like a different thing
I can't access the OP article at the moment, but there's a diagram of the the chain of events that caused the disaster here [1].
I believe Lahars are specifically volcanic, this would be better described as a combination flood and landslide at the same time.
