At 1pm, Tropical Storm Lionrock was estimated to be about 610 kilometers southwest of Hong Kong and is forecast to move north at about 10 kilometers per hour towards the vicinity of Hainan Island.
Under the combined effect of Lionrock and the northeast monsoon, winds are generally strong over the coast of southern China with occasional gales offshore and on high ground.
The rain area over the territory is departing from Hong Kong. However, the outer rainbands associated with Lionrock will still cause widespread heavy rain to the coast of Guangdong. Members of the public should remain on the alert.
Storm surge induced by Lionrock and heavy rain may lead to flooding in low-lying areas. Members of the public should take precautions against strong winds and flooding. Besides, there are rough seas with swells. Members of the public should stay away from the shoreline, and not to engage in water sports.
The adverse weather associated with Lionrock will continue to affect the coast of Guangdong tomorrow.
