Additional Comments

Solar wind conditions remain at background levels, and geomagnetic activity has continued QUIET throughout the early part of the forecast period.
A high-speed stream (HSS) emanating from a transequatorial coronal hole is anticipated to become geoeffective in the coming hours. As this HSS arrives, an increase in geomagnetic activity is expected, with a likelihood of elevated conditions developing during the remainder of the forecast window.
Following the onset of the HSS, solar wind speeds are expected to decline gradually back toward background levels. Despite this easing trend, ACTIVE isolated intervals may still occur at times until the end of the forecast.
