NOAA’s scale runs from G1 to G5. A G2 watch — the kind issued when a cluster of coronal mass ejections is due — usually means high-latitude voltage alarms, small satellite corrections, and radio fade. It is not a national blackout forecast, and treating every watch like one trains people to ignore the real ones.

A watch is a statement that a disturbance is plausible. It is not a statement that your feeder will open. The scale runs from small to severe so operators and the public can tell those nights apart. If every moderate watch is repeated as a national blackout, people learn to scroll past the message, including the day the message is actually large.

The reason operators still staff the desk is orientation. Induced current depends on the storm’s magnetic field, the geology under the lines, and which way those lines run. A moderate storm over resistive rock can stress a transformer that a stronger storm misses entirely somewhere else.

The same solar news does not land the same way twice. Resistive ground pushes more induced current into the wires. The direction of the lines decides how much of the field they collect. A moderate storm can stress a unit that a stronger storm misses over different rock. “National” is the wrong adjective for that kind of damage.

If you live under a transmission corridor, the practical habit is simpler than the physics: know your utility’s outage channel before the sky turns green.

High-latitude voltage alarms are a clue, not a fence. Systems that see these storms more often often know the drill. A moderate event can still matter farther south, on the corridor where geology and line direction cooperate. Staffing the desk is how that difference becomes an ordinary action: watch a neutral current, delay a job, move load.

The outage channel is whatever that utility actually updates when it is busy. Find it before anyone is posting pictures of the sky. Write it on paper. Living under a transmission line does not make you the operator. It means their notice, not a color in the clouds, is the information that applies to the house.
