A low pressure area near the Philippines is expected to enter the South China Sea later this week, prompting concerns it may trigger Hong Kong’s first typhoon of the year, but the city’s weather forecaster has said the possibility is minimal.

The Observatory on Monday said that based on satellite imagery unstable weather linked to a low pressure system was building in waters east of the Philippines.

“We expect this low pressure area to gradually develop over the next two to three days,” said David Lam Hok-yin, the Observatory’s acting senior scientific officer.
