Thanks Andrew, your explanation of the wind gust is agreeable to me. But WU updates rain data at more frequent intervals for other stations in my neighborhood, also when I connect the Acurite console to WU through PC-Connect the rain data is displayed using RF. So I think WU treats my RF rain total values sent from weewx differently or has some issues. May be someone using weewx and an acurite console to communicate to WU could throw some light on how their WU rain total gets displayed. SS
