Taiwan's Central News Agency reported that 60,000 households in the New Taipei, Taoyuan and Hsinchu counties experienced power lost due to the typhoon damage, although power has been restored to most households by 5pm on Sunday (Sep. 4).
China and South Korea bracing for impact
Forecasts now expect the typhoon to head further north-east over the next few days, with above-average sea surface temperatures helping to sustain and strengthen it, NASA wrote.
China's State Flood Control and Drought Relief Headquarters expects Typhoon Hinnamnor to brush the coast in the Zhejiang and Jiangsu province, according to state news agency Xinhua.
It has set emergency response teams to these areas in anticipation of typhoon response and relief work.
The Korean Meteorological Administration expects Hinnamnor to approach the Korean peninsula as early as Monday morning, Sep. 5, with wind speeds of up to 54ms, or around 190kmh.
It has warned that Typhoon Hinnamnor could be one of the most destructive typhoons ever to hit the country, Bloomberg wrote.
South China Morning Post reported Woo Jin Kyu, a weather analyst from the Korean Meteorological Administration, saying:
“We’ve never encountered a typhoon with this level of atmospheric pressure before, which is extremely worrisome because the degree of damage may be beyond our expectation.”
The Korean Herald reported that weather advisories were issued in the southern parts of Korea, including cities of Gwangju, Busan, Daegu and Ulsan on Sep. 4.
An advisory was issued for Jeju Island on Sep. 3.
