category one
Weakest storm classification
Category one designates the lowest level in a classification system, typically indicating minimal severity or intensity.
In hurricane ratings, a category one storm has winds of 74-95 mph—dangerous but the least powerful on the Saffir-Simpson scale.
The phrase appears across various rating systems where numbered categories rank things from least to most severe: It's only a category one, but we're still boarding up the windows.
