Typhoon Koinu: Hong Kong Observatory issues T1 warning signal as city logs hottest October day on record
- Warning issued as Typhoon Koinu edges within 800km of Hong Kong while city swelters in extremely hot weather
- No 1 signal will remain in force for most of Thursday, forecaster says

The No 1 signal will remain in force for most of Thursday, according to the forecaster.
Koinu, named after the Japanese word for the constellation Canis Minor, was expected to skirt the southern part of Taiwan and move towards the coastal waters of eastern Guangdong on Thursday, while maintaining a distance of more than 500km from Hong Kong, the forecaster said.
The Observatory, meanwhile, recorded a temperature of 34.6 degrees Celsius (94.3 Fahrenheit) on Wednesday afternoon.
A “very hot weather” warning was issued at about 7am and authorities told the public they should avoid prolonged outdoor activities and stay in shaded areas as much as possible.
“Koinu’s outer downdraft is bringing generally clear skies and extremely hot weather to South China,” the Observatory said.
