要更详细地查看地图,, 查看塔斯马尼亚战略洪水地图.

Flooding from intense rainfall can cut the Tasman Highway in multiple places. This flooding could be

  • deep
  • impassable, and
  • potentially dangerous. 

The Highway may also be cut in places to the north and south of this plan.  Inland alternative routes are

  • also likely to be cut, and
  • can be more isolated and dangerous.

Flood can isolate communities and properties along the coast for a short time. Waterways in the area are short, so flooding is likely to be for hours rather than days after rain stops.

本指南中的地图显示了任何一年可能发生的%洪水级别。您一生中很可能会经历地图所示的洪水。塔斯马尼亚人需要为不经常发生的洪水事件以及他们可能经历的轻微洪水做好准备。.

Even if your home is not flooded you should prepare for

  • isolation
  • potential power and telecommunications outages.

The Tasman Highway may be cut in multiple places during a major flood event, depending on where the rain falls and how heavy it is. Travel in the area is likely to be difficult or impossible until roads are clear.

Floodwaters will likely isolate many areas along the East coast for a few hours at the most.  If you are safe at home or elsewhere, it is usually best you stay where you are until the flooding subsides. If you need to evacuate, you should leave early, before flood waters rise. Flood waters are likely to disperse quickly, once rain stops.

Check TasALERT.com or listen to ABC local radio for warnings and advice.

  • Bicheno area: ABC Northern Tasmania 89.7 FM or 91.7 FM
  • Swansea area: ABC Radio Hobart106.1FM or 936 AM
  • Triabunna area: ABC Radio Hobart 90.5FM or 936 AM

Note areas outside township areas may lack mobile internet access and local radio coverage

您有洪水风险吗?

East Coast Lows can often bring intense rain that sometimes leads to flooding in areas along Tasmania’s East Coast.  Significant local flooding events happened in 2016, 2011, 1974, 1969, 1923, 1922, 1914, 1911, 1876, 1972 and 1870

我应该怎么做?

  • 查看地图,了解您的住宅或商家是否可能发生洪水。.
  • 评估您的住宅或企业,并做好准备以最大程度地减少潜在的洪水损害。.
  • 洪水期间,检查您是否能够安全地到达家、工作地点或学校。.
  • Prepare a Home Emergency Plan. See 做好应急准备 – A guide for individuals and households to prepare for emergencies . 
  • 如果您可能被隔离并且必须获得服务,您可能需要提早撤离。.

澳大利亚气象局天气预报、警告和观测

该局发布 特大暴雨预警,恶劣天气预警和/或雷暴预警,可能导致山洪暴发 每当 大雨 警告和暴雨发生之间的时间可从一小时到 24 小时或更长时间不等。.

Whenever rain that may lead to flooding along the Swan River or Meredith River is expected, the Bureau will issue a Flood Watch – a “heads up” early advice of forecast weather that may lead to flooding. There are no formal warning levels for waterways in the area as the river systems are too short.

降水观测 at places such as

  • Bicheno
  • Friendly Beaches
  • Swansea, and
  • Lake Leake

can indicate possible flood risks. Given the very short warning times, it is best to act on the BoM warnings rather than wait for any flood alerts during rainfall.

Mt Koonya Radar is useful to be aware in real-time where heavy rain is falling for the areas south of Swansea.  Radar Rainfall estimates can also fill in gaps in areas where there are no rainfall stations. The North East of Tasmania is not well covered by BoM radar.

理解警告和关键信息

留意周围发生的事情。定期查看预报、观测和警报。.

 建议 (黄色): 事件已发生。无即时危险。请保持关注,以防情况发生变化。. 
观察并行动(橙色): 威胁级别有所提高。情况正在变化,您需要立即开始采取行动来保护您和您的家人
紧急警报(红色): 紧急警报是最高级别的警报。您可能面临危险,需要立即采取行动。任何耽搁都可能危及您的生命。. 
社区更新(蓝色): 关于特定事件或事件,受影响社区的具体信息和最新动态。.
事件(白色): an incident is the initial occurrence of an event before it becomes an emergency warning. As soon as an incident is reported, TasALERT published basic information including the type and location of incident.

洪水水位

While no two floods are the same, the following describes what you can expect at different flood levels around the area. Even if your property is not flooded, you need to think about access. Different levels of rainfall can cause flooding depending on its

  • intensity
  • duration
  • how wet the ground is beforehand, and
  • where the rain falls.

Minor flooding can impact low-lying agricultural land. Livestock and equipment near waterways should be moved. There may be low level flooding across some roads, particularly (from North to South):

  • Rosendale Road access to Apsley Gorge, parts of the Campground/ picnic area
  • Tasman Highway
    • South of the Lilla Villa Bridge
    • North of Lake Leake Road
    • South of Springvale Road
    • North of Meredith River
    • Near Sandy Creek, Mayfield Beach
    • Near Trehawke Creek (Buxton River area)
    • North of Lisdillon Rivulet
    • South of Little Swanport River
    • Near Ravensdale Rivulet
  • Lake Leake Road near Whelans Bridge
  • Coles Bay Road East of the Tasman Highway junction (Apsley River)
  • Glen Gala Road, Cranbrook
  • Grange Road, Cranbook
  • Some properties around Llandaff may flood, along with nearby property on Coles Bay Road. There are several low-lying properties along the Tasman Highway that are flood prone.

特大洪灾

Rainfall of about the following amounts will cause major flooding in the area.  This level of rainfall has a 2% chance of happening any given year (based on rainfall records at Swansea up to 2016).

  • 35mm in 1 hour
  • 45mm over 2 hours
  • 54mm over 3 hours
  • 77mm over 6 hours
  • 113mm over 12 hours

Key transport routes most likely to flood include (from north to south):

  • Tasman Highway, many places, but particularly
    • Between Bicheno and Apslawn
    • Extended areas around Cranbrook
    • Near the Cygnet River, south of Cranbrook
    • North of Lake Leake Rd
    • Around the Wye River, south of Crossins Road

    • Maria St
    • several properties on River Street, and
    • the Esplanade area, especially at high tide.
  • At Triabunna, the Esplanade area. This area is also prone to coastal inundation.

Storm water runoff (overland flow) can affect other properties after intense rainfall.

洪水之前

了解您的风险

塔斯马尼亚州经常发生洪水,可能造成广泛而重大的损失。在过去的 200 年里,塔斯马尼亚州有 78 人死于与洪水有关的事故。本指南旨在帮助您了解您所在地区的洪水风险。.

2. 准备您的家庭

制定涵盖风暴和洪水的应急计划

考虑一下在风暴或洪水来临时你会怎么做,这意味着你会有更好的准备,每个人都会更安全。制定一个你的家庭成员都明白的应急计划。有一些清单可以帮助你完善你的计划——请看 做好应急准备 – 个人和家庭应急准备指南。. 

定期检查您的计划,并让家中的每一位成员都模拟可能影响您家庭的洪水场景进行演练。.

准备一个应急包

准备好了

  • 电池供电的收音机和手电筒,备用电池
  • 重要信息,例如您的应急计划
  • 紧急电话号码列表
  • 食物和水
  • 急救箱
  • 橡胶或结实的皮革手套

视情况打包

  • 保暖衣物、结实的鞋子或靴子
  • 药品、眼镜或其他必需品
  • 手机和充电器
  • 宠物食品以及它们所需的其他任何物品
  • 照片和特别的纪念品
  • 重要文件,例如
    • 保险单据
    • 护照和
    • 出生证明

定期测试收音机和手电筒里的电池。.

3. 尽可能降低洪水风险

  • 在购买、维护或开发房产时,请考虑风暴、洪水和其他危险。.
  • 修剪或移除您家中、商铺上方或您物业附近电线上方的树木和树枝。.
  • 保持雨水槽和排水沟畅通。.

4. 与他人联系

认识你的邻居并参与社区活动。一个联系紧密的社区在紧急情况下更安全、更有韧性,并且有助于每个人在事后更好地恢复。检查家人和邻居是否安全,是否了解正在发生的情况。.

5. 保持更新

留意周围发生的事情。定期查看预报、观测和警报。. 

6. 确保安全

  • 看管好孩子。.
  • 为应对可能的电力、供水或网络中断做好准备。.
  • 检查您的应急包是否已准备好。.
  • 避开积水区域,如排水沟。. 永不 在洪水期间徒步、玩耍、骑车或驾车。您无法分辨水下有什么,也无法判断水深或水流速度。在仅 20 厘米的快速流动的水中,很容易被冲走并溺水。洪水可能很危险。.

当地面发生洪水时

  • 将家用物品放在高处以最大程度地减少可能的损坏。.
  • 如果安全的话,请关闭水电煤气。. 
  • 一种防止污水倒灌回家的好方法是将沙袋放入塑料袋中,然后用它们堵住马桶、覆盖排水管和水槽。.
  • 趁还能安全离开就走。.

如果您需要撤离

  • 遵循 SES / 塔斯马尼亚警方 的建议。.  
  • 带上你的应急包。. 
  • 去安全地点或避难中心与亲友会合。. 
  • 让别人知道你去了哪里。.

照顾好您的动物

在紧急情况下,您有责任照顾好您的动物。如果您有宠物和其他动物,在洪水或其他紧急情况下疏散需要更长的时间。在洪水可能上涨之前,将牲畜转移到易受洪水影响的地区。欲了解更多信息,请参阅

避免在风暴期间和风暴过后出行

  • 不要去观光。游客会延误紧急服务并造成事故。.

    • 路面积水
    • 受损的电力线
    • 山体滑坡
    • 损坏的道路
    • 倒下的树木或屋面板。.
  • 切勿冒险涉水。洪水中的大多数死亡和救援事件都与驾车涉水有关。.
  • 在未受洪水影响的路段,请慢行并打开车头灯。.
