Additional Comments

Solar wind speeds have increased due to a high speed stream from a negative polarity coronal hole. This is expected to cause some ACTIVE geomagnetic conditions with an outside chance of a STORM G1 spell during the first period. With above ambient solar wind speeds expected throughout the forecast interval further ACTIVE spells are possible before coronal hole influence starts to wane.
