Nothing "alleged" about it.
I assume you chose your screen name because of some background in the sciences, particularly in weather.
That would imply that you took Science 101 where you were taught about the Scientific Method.
It doesn't allow for miracles to explain what is re-creatable. Mix vinegar and baking soda, and the resulting reaction can't be described as a miracle.
Science doesn't even take a position on whether miracles can occur, but if they do, they're outside the scientific method, and certainly not offered up as an explanation for something yet to be explained.
Supernatural means something outside of natural processes. So, yes, it's outside the realm of science.
Try cosmology. Specifically, the "quantum fluctuation" that "caused" our universe. Or the quantum foam that "causes" multiple universes. And although scientists don't use "supernatural" to describe quantum entanglement and "instantaneous" correlation at a distance, it is "supernatural".
In particular, quantum theory is non-local: it predicts entanglement between distant systems leading to correlations that cannot be explained by any theory based only on local variables [1], as demonstrated by Bell inequality. All experiments are in remarkable agreement with quantum theory. Hence, the physics community faces a very strange worldview: in theory, everything is entangled, but, in practice, decoherence makes it impossible to reveal this entanglement. In addition to its "experimental metaphysics" [2] aspects, quantum entanglement has recently gained much interest and respect because it is at the heart of quantum information processing. The general idea is that entanglement provides means to carry out tasks that are either impossible classically (quantum cryptography) or that would require significantly more steps to perform on a classical computer (searching a database, factorization) [3].
