An apparatus for detecting a storm, including a partially transparent housing defining a cavity and a suspended magnetic element positioned within the cavity. The magnetic element is rotatable in a first plane and pivotable in second plane and third planes, wherein the second plane is perpendicular to the first plane and the third plane is perpendicular to the first plane and perpendicular to the second plane. A rapid pivot of the magnetic element away from the pull of gravity signals a close proximity of a storm. A first sensor operationally connected to the magnetic element for measuring the deflection of the magnetic element, dampening fluid substantially fills the cavity, a second sensor positioned within the housing for measuring the degree to which the magnetic element is level, and a laser operationally connected to the magnetic element and positioned to emit a beam of light corresponding to the orientation of the magnetic element. |
