This week's deluge has already drenched Hong Kong with the equivalent of almost half the average annual rainfall and there is more to come, with the rain expected to continue into next week.
Engineers say the landslide count for the past two days is fast approaching the total number for the whole of last year.
Between Tuesday morning and 5.15 pm yesterday, a rain measuring station at the Chinese University near Sha Tin gathered one metre of rain.
The average annual rainfall in Hong Kong is 2.25 metres.
Between Tuesday and 5.30 pm last night there had been 141 landslides compared with 163 for the whole of last year, although officials say that figure was lower than average.
No loss of life had been reported, but eight people were injured in the past 72 hours and rescuers were last night still digging for 73-year-old Ma Shuk-fong who is thought to have been buried in a landslide at the Ten Thousand Buddhas Monastery in Sha Tin.
Dr Andrew Malone, the SAR's Principal Geotechnical Engineer, described the rainfall figures as 'unbelievable and remarkable'.
