The trough of low pressure lingering over the south China coast continued to bring heavy rain to Hong Kong today (Monday, 11 June 2001) and the Observatory issued both the Amber and Red Rainstorm Warning Signals. This is the 7th consecutive day that the Amber Rainstorm Warning Signal was issued since 5 June, the longest record since the revised Rainstorm Warning System was operational in 1998. According to past records, the Observatory also issued the Amber Rainstorm Warning Signal for 4 consecutive days on 22-25 August 1999 and 1-4 August 2000.

The heavy rain occurred mainly in the urban areas, Lantau Island and the central part of the New Territories.
