The Hong Kong Observatory stated yesterday that it began offering a nine-day weather forecast service on April 1st, extending the forecast period from seven to nine days. This spans two weekends, allowing citizens to grasp weather changes earlier and plan their activities and preparations in advance.
According to the information provided, the ability to enhance weather forecasting capabilities and extend the forecast period is attributed to technological advancements and increased reliability in numerical weather prediction models. Data shows that the average accuracy rate of the Hong Kong Observatory's weather forecasts is now 90% for the first to third days, 85% for the fourth to seventh days, and approximately 80% for the newly added eighth to ninth days.
