The NOAA Space Weather Prediction Center has observed extreme (G5)
geomagnetic conditions Saturday morning and expect severe (G4)
conditions to continue through the weekend.
* A Geomagnetic Storm of this strength can cause multiple and
widespread issues with various power and communication systems.
* Widespread voltage control problems may occur; some power grid
systems may experience component failures, disruption of service
and protective device trips. This could result in blackouts.
* Pipeline currents can reach hundreds of amps.
* GPS and other satellite navigation may be degraded or
unavailable for days.
* High Frequency (HF) radio propagation may be impossible in many
areas for one or two days.
* Low-frequency radio navigation can be out for hours.
* Aurora may be visible at much lower latitudes.
