I want to know the answer to the following question:
What is the name of the event that caused major flooding in the western US?
All the background I'm provided with is that "The narrow canyons of many mountain areas in the west and severe thunderstorm activity during the summer lead to sometimes devastating flash floods as well, while Nor'Easter snowstorms can bring activity to a halt throughout the Northeast (although heavy snowstorms can occur almost anywhere).". Is that enough to answer the question?
Answer: no
