The Hong Kong Observatory has warned that an area of low pressure near the Philippines’ Luzon could develop next week and affect the coast of southeastern China.

The forecaster said on Saturday that the weather would be mainly fine over southern China early next week, with persistently very hot days under the influence of an anticyclone aloft.

But conditions were expected to become unstable later in the week.

“An area of low pressure may develop near Luzon within the broad trough of low pressure early to midweek next week, and move in the general direction of the seas east of Taiwan to the vicinity of the coast of southeastern China in the middle and latter parts of next week,” the Observatory said.

“Its chance of development over the South China Sea still cannot be ruled out, but it remains rather uncertain.”
