'Severe' geomagnetic storm could blow power grid with satellite, radio blackouts possible during Milton
NOAA's Space Weather Prediction Center (SWPC) said that the severe (G4) geomagnetic storm could affect the power grid, as well as GPS and radio blackouts and impacts on satellites. "Possible widespread voltage control problems and some protective systems may mistakenly trip out key assets from the power grid," the SWPC said Wednesday.
