Thin branches and tree trunks sway, and the wind is felt by the hand.
At Sea:
The sea is rough, not very large waves are well developed in length; many white horses are formed.
Power systems: High-latitude power systems may experience voltage alarms,
long-duration storms may cause transformer damage.
Spacecraft operations: Corrective actions to orientation may be required by ground control;
possible changes in drag affect orbit predictions.
Other systems: HF radio propagation can fade at higher latitudes,
and aurora has been seen as low as New York and Idaho (typically 55° geomagnetic latitude.).
