The Hong Kong Observatory said it will consider raising the typhoon warning signal No. 3 on Monday night as Typhoon Fengshen gradually moves closer to the territory, while temperatures are expected to drop to 19 degrees Celsius the following day.

The observatory said it will raise the Strong Monsoon Signal later on Sunday and consider directly replacing it with the Strong Wind Signal, No. 3 on Monday evening without issuing the Standby Signal No 1.

“With Fengshen edging closer to the coast of Guangdong gradually tomorrow, the Observatory will consider issuing the Strong Wind Signal, No. 3 directly to replace the Strong Monsoon Signal around tomorrow evening,” the HKO said, adding that the typhoon as expected to come within 800 kilometers of Hong Kong on Sunday night.

At 4 pm Sunday, Fengshen was centered about 620 kilometers south-southeast of Dongsha and was forecast to move northwest at about 26 kilometers per hour across the central and northern parts of the South China Sea.
