...EXTREME GEOMAGNETIC CONDITIONS OBSERVED AND CONTINUED SEVERE GEOMAGNETIC STORMS EXPECTED TO CONTINUE THROUGH THE WEEKEND...

The NOAA Space Weather Prediction Center has observed extreme (G5)
geomagnetic conditions early Saturday morning and expects severe
(G4) conditions to continue through the weekend.

A geomagnetic storm of this strength can cause multiple and
widespread issues with various power and communications systems.
Widespread voltage control problems may occur, and some power grid
systems may experience component failures, disruption of service,
and protective device trips. This could result in blackouts.

GPS and other satellite navigation may be degraded for days.

HF/VHF/UHF radio propagation may be impossible in many areas for
one to two days.

Low-frequency radio navigation can be out for hours.

Aurora may be visible at much lower latitudes.
