Raining animals is a rare meteorological phenomenon in which flightless animals fall from the sky. Such occurrences have been reported in many countries throughout history. One hypothesis is that tornadic waterspouts sometimes pick up creatures such as fish or frogs, and carry them for up to several miles.
Imagine a world where raining animals are a regular occurrence - say, most days on the tropical rainy season. Could a marine apex predator adapt to such a meteorological feature in order to take advantage of it, in terms of mid-air feeding? If so, what adaptations would it need, and what would it look like?
I don't expect that a shark which evolved for this would necessarily still look exactly like a real world shark, so a sharky final appearance is not a requirement for answers. Other marine predators such as orcas, barracudas and mantas are also valid candidates for this niche, and don't need to look exactly like the ones from our world's after the necessary evolutionary adaptations.
Being directly threatening to humans is also not required (I think the tornadoes are already enough of a menace).
Edit: I see people assuming that animals will always fall on land after the tornado goes. Just remember that tornadoes may flood coastal areas, giving marine life some chance to fall into water. Asides that, please assume that the tornadoes may also happen over water, far from land sometimes.
