G4: " Induced pipeline currents affect preventive measures, HF radio propagation sporadic..."

G5: " Pipeline currents can reach hundreds of amps, HF (high frequency) radio propagation may be impossible in many areas for one to two days..."

HF propagation is flaky at the best of times. It's affected by the day/night cycle and by the weather.

Looks like G5 is the highest level and the scale system is used by NOAA.
