With the development of alternative communication channels, such as radio and TV, Dial-a-Weather telephone service, and Observatory website, in disseminating weather information and warnings, the signal stations were progressively closed in the late 1970s. It was fired once whenever a strong gale of wind was expected. When these signals are interchanged indicating an anticipated change in the direction of the gale or storm, the wind shift may be expected within a few hours. Showers were also likely on Thursday, with the conditions easing by the weekend. Moreover, the Director of the Observatory reported in the Annual Report that owing to the lack of weather information from the mainland, it was very difficult to use the signal effectively for giving warning of strong monsoon winds in winter.

Gusts may exceed 180 kilometres per hour. The signals are now preserved as historical exhibits, such as those displayed at the Observatory Headquarters and Cheung Chau Meteorological Station. In 1969, there were altogether 39 signal stations. The signals are represented as a set of numbers and symbols. 8 to No. All precautions should have been completed prior to the issuance of No. This practice is still valid today.

Aberdeen Police Station was vacated in October 1969 and the signal mast were removed to the top of the Fisheries Research Station in Aberdeen early in 1970. In 2013, Lau Fau Shan has replaced Wetland Park as a reference anemometer station. In addition, equipment for showing full signals was installed in Aberdeen Police Station, Castle Peak Police Station, Cheung Chau Police Station, Stanvac Installation in Lai Chi Kok, Sai Kung Police Station, Shau Kei Wan Marine Licensing Office, Stanley Village Police Station, Tai O Police Station and Caltex Oil Company Depot in Tsuen Wan.

The Hong Kong Observatory issues the warning signal if a tropical cyclone approaches within 800 kilometres (500 mi) of Hong Kong and poses a threat of deteriorating conditions in Hong Kong. It was the first time the No 9 signal had been issued since Super Typhoon Mangkhut on September 16, 2018, which gradually intensified into a powerful No 10 storm. Intensifying winds resulted in the No 9 storm signal, the second-highest storm warning, being issued for Hong Kong at 1.30am on Wednesday. A gale ranges from 63 to 87 kilometres per hour and storm from 88 to 117 kilometres per hour. 10 warnings generally occur in intervals of around four years or less, except for the period from the 1980s to 2000s when only two such signals were issued, for Typhoon Ellen in 1983 and Typhoon York in 1999.
