Additional Comments

Solar wind speeds are starting to increase as the expected coronal hole high speed stream becomes geo-effective. This will likely cause some geomagnetic enhancements of up to STORM G1 during the first forecast period. Effects should start to wane gradually into the second and third forecast period before ambient conditions return.
