T10 is the highest-level alert reserved for most powerful typhoons; the Post looks back on some of the strongest storms in recent years
Hong Kong is experiencing its first No 10 hurricane signal in two years with Typhoon Wipha expected to skirt the city at noon on Sunday. The last time a No 10 situation hit the city was in 2023, when Super Typhoon Saola caused 86 injuries.
Wipha escalated rapidly from a No 9 signal to the top warning in two hours at 9.20am, with the Hong Kong Observatory warning that it would “pose considerable threat” to the city.
The No 10 signal indicates that hurricane-force wind is blowing or is expected to blow with sustained speeds reaching 118km/h (73mph) or above. Gusts may also exceed 220km/h.

Super Typhoon Saola (2023)
Saola’s approach prompted the Observatory to issue the No 10 signal as it whipped past Hong Kong, skirting only about 40km (25 miles) to the south-southeast of the Observatory headquarters in Tsim Sha Tsui.
