The Hong Kong Observatory will raise the T1 storm warning between noon and 3 pm on Friday as Tropical Cyclone Yinxing edges closer to the city. The forecaster said on Friday that Yinxing had entered within 800 kilometres of Hong Kong. “Under the combined effect of Yinxing and the northeast monsoon, there will be a few showers over the coast of Guangdong during the weekend.

It will be windy offshore and on high ground,” the Observatory said. Yinxing has prompted mass evacuations in some coastal communities in the Philippines, where the government has also issued flash flood and landslide warnings. In the northern and eastern parts of Taiwan, the storm is expected to bring heavy rains on Thursday and Friday.

The Observatory said it would consider raising a higher typhoon signal depending on Yinxing’s “change in intensity and the change in local wind conditions.” The weekend is forecast to be windy with a few showers and temperatures between 22 and 28 degrees Celsius, according to the Observatory. The No.

1 signal is the “Standby” signal. It is issued when a tropical cyclone is centred within about 800 kilometres of Hong Kong and may affect the territory. Tropical cyclones – which get their energy from warm ocean water – are strengthening and become ever more destructive because of warming seas.

Over 90 per cent of excess heat in the atmosphere is ending up in oceans, according to NASA, as rising greenhouse gases prevent it from escaping to space. Support HKFP |.
