General Situation:

The trough of low pressure over the northern part of southern China will move southwards gradually. Showery activity will increase over the coast of Guangdong in the next couple of days. Besides, Tropical Cyclone Linfa will move towards the vicinity of Luzon to Taiwan in the next few days. However, under the influence of another Tropical Cyclone Chan-hom further east, there are still uncertainties over the moving track of Linfa.

  2. "9-day Weather Forecast" provides general indications of the trends in weather for the coming 9 days. For detailed description of today's weather forecast, please refer to "Local Weather Forecast".
  3. The accuracy of forecast generally decreases with forecast period. The average accuracy of weather forecast for the next one to three days, four to seven days, and eight to nine days are about 90%, 85% and 80% respectively.
  4. The accuracy of forecast also varies for different weather systems in different seasons. Generally speaking, weather in spring and summer such as fog, tropical cyclone and severe convective weather is more changeable, resulting in higher uncertainty of forecast.
