The Observatory has replaced tropical cyclone signals by the Strong Monsoon Signal, meaning that the monsoon has become the dominant force in contributing to Hong Kong's strong winds.
NALGAE has weakened into a severe tropical storm. At 20 HKT, NALGAE was centred about 590 km (320 NM) SSE of Hong Kong. The #1 Standby Signal was issued at 10:40 HKT today.

NALGAE has formed an eye and its structure improved considerably. The storm is expected to intensify further before landfall due to the favourable environment there, but will suffer a great loss in intensity as it crosses Luzon. Sea temperatures in South China Sea are rather low after the passage of NESAT, and this will affect NALGAE's re-intensification there.
