Topic: Gust Bust on Wunderground

[rhwxman]

Trouble with the Gust reports on Wunderground.  When winds are calm (mostly at night) the gust numbers do not set to zero.  Instead the same number reports all night and day.  First it was 2 mph, now it's 5 mph.  When a real gusts occurs, that correct gust number displays, then it defaults back to the error value when winds go calm.  What is going on here?
