What exactly does a coronal hole high speed stream do to amateur radio signals? How long does it last?

If the magnetic fields of the Wind Stream and the earth connect it causes a geomagnetic storm. How long does it last. Anywhere from a few hours to 5 days depending on the size of the hole and if it is in a Geoeffective Position.
