Degraded HF propagation conditions possible:
No significant degraded periods expected.

Depressed MUFs are likely to continue unless solar activity increases.

PLEASE NOTE:
Space weather conditions can frequently be determined by short 
timescale events that cannot be forecast a week in advance,
particularly at solar maximum.
