  • The Observatory launches the “Regional Information on Heavy Rain and Thunderstorm” webpage

  • Tuesday, 11th September 2018

When the Observatory issues the “Announcement on Localised Heavy Rain”, “Special Announcement on Flooding in the northern New Territories” or “Thunderstorm Warning”, regional information will be given in the message according to the circumstances. To facilitate the public to obtain such information in graphical format at a glance, the Observatory launches a new webpage on “Regional Information on Heavy Rain and Thunderstorm” today (11 September 2018). Users can choose to display on an interactive map the affected regions mentioned in these warning and announcements, as well as the recorded regional rainfall and lightning locations, so as to take appropriate preventive measures.

Members of the public are welcome to browse the “Regional Information on Heavy Rain and Thunderstorm” webpage at:
https://www.hko.gov.hk/rhr/main.html
