Additional Comments

Solar wind speed is still increasing subject to influences from a coronal hole high-speed wind stream. Another recurring coronal hole is becoming geoeffective, arriving with faster high-speed wind streams by the second forecast interval, further enhancing the geomagnetic activity. As a result, more ACTIVE periods are expected to occur frequently over the next several days, with a high probability of experiencing MINOR STORMS in the first two forecast intervals.
