Solar storms are no joke -- they can knock out power grids and leave entire towns in the dark. Unfortunately, the forecast model the US National Oceanic and Atmospheric Administration (NOAA) uses only shows the current geomagnetic activity for the entire planet. It can give us a pretty good idea of when a solar storm will happen, but it can't tell us where it will hit the hardest. That's why NOAA has developed a better forecast model that can pinpoint which locations in the world will be affected the most. For instance, it can show if a storm's bound to have a bigger impact on a European country than on the US, so power companies there can take the necessary precautions.
