I was feeling uncomfortable when the rain came around 6 pm, thinking "it came too early!", there were several rain events last night, but none of the rain did not last very long at Winchester area (< 1 hour around 6 pm, then about 20 min around 8:30pm, and < 1 hour around midnight). It was so windy that the relative humidity did not stay high, but stayed around 70%. Thus, this series of rain events was not creating a risk of fungal diseases. I'm more worry about damages done by wind. I hope your vineyards were OK.
