GEOMAGNETIC STORM WATCH (G3-CLASS): Strong G3-class geomagnetic storms are possible during the early UT hours of March 31st when a Cannibal CME is expected to hit Earth's magnetic field. During such storms, naked-eye auroras can descend into the USA as far south as, e.g., Illinois and Oregon (geomagnetic latitude 50o).
