• HANNA will slowly move west northwestward over the Taiwan Strait while gradually weakening. It is forecast to make landfall over the coast of Guangdong or Fujian, China tomorrow morning or afternoon as a severe tropical storm. Rapid weakening will ensue as the tropical cyclone moves further inland over Guangdong, China. HANNA is forecast to become a remnant low on late Wednesday or Thursday.
Considering these developments, the public and disaster risk reduction and management offices concerned are advised to take all necessary measures to protect life and property. Persons living in areas identified to be highly or very highly susceptible to these hazards are advised to follow evacuation and other instructions from local officials.
