A large-scale power outage is being reported: "Cuba suffers third nationwide blackout in two weeks as fuel crisis deepens". Widespread outages can be caused by severe weather, grid failures, or – relevant to what this site tracks – a strong geomagnetic storm inducing damaging currents in transformers.
What this means for you
Most space weather passes without anyone noticing – but events like this are exactly why we watch the data. If conditions escalate, the first things affected are GPS accuracy, shortwave radio and, in severe cases, power grids. Now is a good moment to make sure your devices are charged and you know where your backup light sources are.
We track this in real time on our Space Weather Command Center – live storm levels, aurora maps and official NOAA alerts, explained in plain English.
