Super Typhoon Hinnamnor is slowly moving in a southwesterly direction and the Central Weather Bureau says it have the biggest impact on Taiwan between Sept. 2 and 4. A sea warning may be issued on Sept. 2, and a land warning is also possible if its path continues deviating towards the west or its storm circle increases.
Satellite images show Super Typhoon Hinnamnor's storm circle is expanding. According to the Central Weather Bureau, a tropical depression and cloud system in the south gradually merged into the typhoon's periphery and it believes the typhoon's storm circle and strength will both increase. A sea warning may be issued on Sept. 2.
Hsieh Pei-yun, Forecaster, Central Weather Bureau: “If we make a forecast based on its current path and storm circle, there is the possibility that we will issue a sea warning tomorrow. If the typhoon continues moving in a westerly direction or its storm circle expands even more, then we may issue a land warning.”
The CWB said that although the eye is still located quite far from Taiwan, the typhoon's periphery will start affecting Taiwan on the evening of Sept. 1, with the north seeing rain. Other regions will see afternoon thundershowers. Between now and the morning of Sept. 2, the typhoon will enter an area where the guiding airflow is not as obvious and it will hover above the waters southeast of Taiwan. It won't start moving north until it receives the influence of the next guiding airflow on Sept. 3. The effects of the typhoon will be most strongly felt between Sept. 2 and 4.
Peng Chi-ming, Chief Executive Officer, WeatherRisk Explore Inc.: “The northern and northeastern regions will start seeing rain. The rain will be the most intense in the period from Friday to Saturday.”
The typhoon may bring strong to whole gales to Tainan and areas to the north as well as the Yilan and Hualien regions. Will the criteria for typhoon leave be met? The CWB says that will be up for local governments to determine.
