Is the weather forecast for rain tomorrow? Are the drifting events still open then? Do the drifting events have a fixed time period every day?

Float time: 9：00-17：00, generally drifting when there’s light rain. Heavy rain should stop then! I haven’t been on a rainy day to go
Floated time 9:00-17:00, light rain usually has a break-in, heavy rain should just have to stop then! I haven’t gone on rainy days yet.
