likely to be light but may become moderate to strong late in the day
if the 28 September CME arrives earlier than expected. Geomagnetic
conditions are likely to be quiet to unsettled but active conditions
are possible later if the CME arrives. Normal HF propagation
conditions are likely with a small chance of short wave fadeouts
(radio blackouts).
