HKO current HAIMA forecast at 3pm October 18th: “The movement will be west-northwest at around 25 km per hour in the next 24 hours. Haima will move towards the northern part of Luzon today and tomorrow.

At 7:45am October 18, the HKO issued the following statement: Sarika is tracking towards Hainan and will make landfall around noon today. Its direct threat to Hong Kong will decrease gradually. Under the combined effect of Sarika and the northeast monsoon, strong winds are expected to persist over offshore waters for most of the time today. The Observatory will consider issuing the Strong Monsoon Signal to replace the Strong Wind Signal, No. 3 later today.
Here is a summary of the Strong Monsoon Signal:
The Strong Monsoon Signal is issued when winds associated with the summer or winter monsoon are blowing in excess of or are expected to exceed 40 kilometres per hour near sea level anywhere in Hong Kong. In very exposed places, monsoon winds may exceed 70 kilometres per hour. Winds associated with the monsoons are generally more persistent than those brought by tropical cyclones and may last for days. If you are not well sheltered from the monsoon, precautions should be taken against strong gusty winds. Flower pots and other objects likely to be blown away should be taken indoors. Engineers, architects and contractors should ensure that all scaffoldings, hoardings and temporary structures are secured. If necessary, owners of small craft should make arrangements for the safety of their boats and make sure that all deck fittings are firmly fastened. Those engaging in water sports or operations at sea should take special care against high winds and rough sea conditions. Rough seas and swells may affect the coast. You should beware of the risk and stay away from the shoreline for safety sake. Drivers using highways and flyovers should be particularly alert to strong gusts.
