An 'event'

In the past the Weather Bureau has reported on the weather which could be described as sunny, dry, cold, wet, windy and a multitude of other conditions.

But recently the Bureau has discovered something new...the weather event. Mostly as a 'serious weather event' too.

In this context I would think that 'weather' and 'event' amount to a tautology but I suppose we should allow the Bureau some idiosyncrasies.
