黃色暴雨警告信號通常在香港天文台識別大雨即將來臨時發出。此信號表明已經出現或將要出現大雨。值得注意的是，根據情況變化，警告信號可能在發出後不久或持續一段時間。黃色暴雨警告信號旨在提醒公眾注意可能導致交通擁堵和其他影響的大雨。香港天文台會根據降雨量的預測和實際情況，判斷何時發出和取消不同的暴雨警告信號，以保障市民的安全。
此外，在暴雨警告信號生效期間，建議留意防暴雨措施和隨時關注天氣更新。對於校園、企業和活動策劃者，應該密切關注警告信號的變化，以安排相應的應對措施，如延遲或取消課堂、活動或工作。當接獲黃色暴雨警告信號時，公眾應該保持警惕，避開可能受到影響的區域，並且遵循當地當局的建議和指示。
What are the criteria and thresholds for issuing a yellow rainstorm warning signal in Hong Kong?
在香港，發出黃色暴雨警告信號是基於特定的標準和門檻。根據香港天文台的政策，黃色暴雨警告信號通常表示預料有大雨，每小時可能達30毫米。這可能會導致一般性的水浸情況，民眾應該保持警惕 28。
觸發黃色暴雨警告的門檻是相對較低的，通常意味著短時間內可能會有暴雨天氣 29。這項警告能夠提醒公眾和相關機構做好應對措施，以應對可能導致交通混亂和水浸的情況。
此外，香港天文台在設定警告信號時還會根據風險水平和天氣預測準確性等因素進行考量 27。因此，當預測到大雨並且達到特定標準時，就可能會發出黃色暴雨警告信號，提醒市民注意可能出現的降雨情況 32。
總的來說，香港實行的黃色暴雨警告信號制度旨在在有需要時提供預警，以保障市民的安全和公共秩序。當天氣情況可能導致暴雨時，這些警告信號能夠幫助市民做好應對準備，減少可能造成的影響。
How does the Hong Kong Observatory determine when to upgrade a yellow rainstorm warning to a higher level warning?
The Hong Kong Observatory issues different levels of warnings based on weather conditions. The upgrade from a yellow rainstorm warning to a higher level warning, such as an amber or red rainstorm warning, depends on the intensity and persistence of the rainfall. When heavy rain is expected to continue, the Observatory may consider raising the warning level to ensure public safety.
According to the Hong Kong Observatory, a yellow rainstorm warning is issued when the observed or forecast rainfall intensity reaches or is expected to reach 30 millimeters per hour. If the rainfall intensifies further and poses a higher risk of flooding or other weather-related hazards, the Observatory may upgrade the warning to an amber or red rainstorm warning 36.
The decision to upgrade a warning is based on ongoing weather observations, such as rainfall intensity, wind speed, and other meteorological factors. Meteorologists at the Observatory closely monitor these parameters to assess the changing weather conditions and determine the appropriate warning level.
Therefore, the Hong Kong Observatory will typically issue an upgrade to a higher level warning, such as an amber rainstorm warning, when the rainfall intensity increases significantly and the risk of adverse weather impacts rises. By following these procedures, the Observatory aims to provide timely and accurate warnings to help the public prepare and stay safe during severe weather events.
What actions should residents take when a yellow rainstorm warning signal is issued in Hong Kong?
When a yellow rainstorm warning signal is issued in Hong Kong, residents should be prepared to take appropriate actions to ensure their safety. Here are the steps that residents can follow:
Stay Informed: Keep yourself updated with the latest weather updates and warnings issued by the Hong Kong Observatory 40.
Avoid Outdoor Activities: It is advisable to stay indoors and avoid going outside unless absolutely necessary when the yellow rainstorm warning signal is in effect.
Secure Loose Objects: Secure or bring indoors any loose objects outside your home that could be blown away by strong winds accompanying the rainstorm 39.
Check on Vulnerable Individuals: Make sure to check on elderly family members, children, or individuals with special needs to ensure their safety during the rainstorm.
Stay Away from Flooded Areas: Avoid walking or driving through flooded areas as they can be dangerous due to hidden hazards like open manholes or debris.
Prepare Emergency Kit: Have an emergency kit ready with essential items such as food, water, flashlight, and a first aid kit in case of power outages or emergencies 41.
By following these guidelines and staying alert, residents can better protect themselves and their families when a yellow rainstorm
