Answer:
A. Definition 1
Step-by-step explanation:
Personally, I'd say Definition 1, because storms tend to lesson in intensity before dying out completely. The other definitions don't make sense because the meterologist said that the storm would be completely over a few hours after its abates, so it cannot be ended already, as definition 2 states, and stormes dont deduct or omit, and they also aren't carvings.
Hope this helps :)
