COMMENT: SWS SWF HF Communications Warning 29 was issued on 28 
March and is current for 29-31 Mar. Maximum usable frequencies 
(MUFs) on UT day 29 Mar were mildly to strongly enhanced. Near 
monthly predicted values with enhancements are expected for 30 
Mar. Mildly to moderately degraded conditions may be experienced 
on 31 Mar-01 Apr due to anticipated geomagnetic activity. There 
is a chance for shortwave fadeouts on daylight HF circuits over 
the next few days.
