Additional Comments

The solar wind speed remains elevated due to the effects of a coronal hole. This enhanced speed increases the likelihood of isolated ACTIVE intervals. We anticipate that the solar wind speed will gradually decrease, diminishing the chances of activity by the end of this forecast.
