黃色暴雨警告信號通常在香港天文台預測到有可能出現大雨的時候發出。當預料有大雨即將來臨或正在降下時,天文台會發出黃色暴雨警告信號,提醒居民做好應對準備。在暴雨警告系統中,黃色信號是最低級別的信號,表明預期的降雨量可能會對市民生活造成一定程度的干擾。

透過當地氣象局的預警系統,如有可能的大雨情況,居民可以提前做好應對措施,例如確保房屋排水系統暢通,避免外出等。此外,當接到黃色暴雨警告信號時,市民應保持警惕,留意局部水浸及交通阻塞的可能性。

若想瞭解更多有關暴雨警告系統的詳細資訊,可以查閱香港天文台或相關政府網站上提供的相關資料。香港具有完善的天氣預警系統,幫助市民應對不同級別的極端天氣情況。

What are the criteria for issuing a yellow rainstorm warning signal in Hong Kong?

黃色暴雨警告信號通常在香港出現時,代表預料或降下激烈雨勢,絕大部分地區可能會有明顯積水。當天氣狀況有機會引致交通中斷或影響日常活動時,政府通常會考慮發出黃色暴雨警告信號。

根據香港天文台的資訊 28,黃色暴雨警告信號是基於下列一些標準來發出:

  • 預測降雨量總數大於或等於70毫米,直至警告被撤銷。
  • 已經出現嚴重破壞的天氣條件或降雨情況,但降雨量未達到紅色暴雨警告信號的條件。

在發出該警告信號後,市民應該保持警覺,並注意可能對日常活動帶來的影響。建議減少外出活動,特別是在交通繁忙的時段。同時,隨時留意機構發佈的最新消息和指引,以確保個人安全。

若需要進一步了解有關雨量警告信號的更多信息,可查閱香港政府教育局之相關資訊 27

How does the Hong Kong Observatory determine the intensity of rainfall to issue a yellow rainstorm warning signal?

根據香港天文台的標準,黃色暴雨警告信號是根據實際或預期降雨強度來發出的。這個信號意味著短時間內降雨量已達每小時五毫米或預期可能達到相同水平 33。預測和監測降雨強度是決定發出各個暴雨警告信號的重要因素。香港天文台的SWIRLS系統(短期局部強降雨預報系統)用於預測強降雨 31

最近的相關新聞和情況

根據報導,近期香港可能發生強風暴雨,以至可能引發黃色暴雨警告信號 36。另外,香港天文台在面對熱帶風暴和颱風時,還會發出相應的警告,如T3警告信號 34

同時,你還可以參考更多有關天氣極端情況的資訊,如氣象組織的Severe Weather Information Centre 3.0,該中心提供有關極端和高影響天氣的權威警報和信息 35

總的來說,香港天文台在決定發出黃色暴雨警告信號時,主要考慮降雨強度和預測情況。密切關注天氣預報和局部強降雨預報系統的信息,以便及時應對可能的風暴和暴雨情況。

What actions should individuals take when a yellow rainstorm warning signal is issued in Hong Kong?

當香港發出黃色暴雨警告信號時,個人應該採取以下行動以確保安全:

  1. 留在室內: 避免外出活動,尋找安全的室內空間避雨。關好窗戶和門,以防雨水滲入室內。

  2. 關注天氣資訊: 收聽廣播或關注天氣相關的消息,以便隨時了解最新情況和指引。

  3. 緊密監控水勢: 如果住在易受水災影響的地區,應該密切關注周圍水勢的變化,做好應對準備。

  4. 避免靠近淹水道路: 避免靠近河流、下水道、淹水路段等危險區域,以免受到水災影響。

  5. 準備應急包: 準備一些必要的應急物品,如飲用水、食物、藥品、手電筒等,以應對可能出現的情況。

  6. 遵循當地指引: 遵循當地政府和相關機構的指引,如有疏散或其他特別措施,應盡快執行以確保個人安全。

在接到黃色暴雨警告信號後,個人應該保持警惕,儘量遠離危險區域,做好應對準備以應對可能出現的極端天氣情況。 38
