Typhoon "Koinu" has slightly intensified this morning and continued to move westward approaching the coastal area of Guangdong.
According to the present forecast track, "Koinu" will continue to move westward and approach the Pearl River Estuary in the next two days. Under the combined influence of "Koinu" and the northeast monsoon, windspeed in Macao is expected to increase during early hours of tomorrow, with force 5 to 6 gusty northerly winds. As a result, there is a high chance of issuing Signal No. 3 from 1 a.m. to 3 a.m. tomorrow. It is expected that there will be more showers later tomorrow and showers will be more frequent early next week, heavy at times.
Although the circulation of "Koinu" is small, there is still uncertainty regarding its intensity changes and track. On Sunday(October 8th), there is a possibility that it may enter within 150 kilometers of Macao as a severe tropical storm, so the possibility of issuing a higher typhoon signal cannot be ruled out.
SMG will closely monitor the development of "Koinu" and assess the possibility of flooding caused by storm surge in low-lying areas. The public is advised to pay attention to the latest weather information.
Remarks: The probabilities of issuing severe weather warning signals for the next one or two days are provided in the table. Public can learn the possibility of being affected by the tropical cyclone over the specific period of time in Macao so that necessary precautions can be well prepared earlier. Please keep notice of our latest information.
