Starting time of rainfall at Muara Putus

Dear Ardhi,

Thank you very much for your report.

By the way, just to make sure, I have a question about the starting time
of rainfall at Muara Putus in the evening of 11th. According to the AWS
observation there, it started to rain at 1840 LT. But your report
mentioned that the starting time was around 1730 LT. Does it mean that
very light rain already started at the time there?

Best regards,
Hideyuki
