Question

6 inches?

Answer 1

The Hong Kong Observatory has declared June 2008 its wettest month ever on record, with records dating back to 1884. Up to midday on Monday June 30th, the total rainfall recorded at the Hong Kong Observatory was 1,346.1mm (53 inches) breaking the previous record set in May 1889. The previous rainfall record was 1,241.1mm (49 inches).  The heavy rain is being attributed to active southwesterlies over the south China coastal areas during the first half of the month. On June 7th in particular, a heavy storm gave as much as 145.5mm (5.73 inches) of rain in one hour.
