Veteran meteorologist warns that global warming could mean more instances of extreme wet weather in Hong Kong are likely to occur in long run

Hong Kong has issued 51 rainstorm warnings so far this year, including four top-tier signals, surpassing a record held for the entirety of 2001, the Post has found.

The record was broken at 11.45am on Wednesday when an amber rainstorm warning signal was raised.

The four black rainstorm warnings issued were in effect for a total of 17 hours and 35 minutes during the current summer, a historical high for the season since the signal system was revamped in 1998.
