Jupiter, we have learned, has storms big enough to encompass the entire land mass (and, for that matter, the oceans) of the Earth.
Not too far, therefore, from an Oklahoma spring:

Moving down to the lowest level of the house won’t save you, unless your house goes as far down as the CN Tower goes up.
