Additional Comments

Solar wind speeds are currently at elevated levels due to coronal hole influence. This is expected to continue through the first forecast period which may lead to further STORM G1 geomagnetic conditions as we have already seen through the previous day. These effects are expected to wane during the second and third periods although there is uncertainty on the extent of the coronal hole and therefore a return to ambient conditions is difficult to predict.
