Storms often affect the D’Entrecasteaux Channel area, bringing heavy rain and damaging winds. Stormwater runoff and flash flooding can affect many areas during a severe storm. Areas that are prone to flooding from rivers (riverine flooding) are:

• Snug – low lying areas to the South of Snug River downstream of the Channel Hwy, mainly near the Esplanade North, Pybus St & Gillies St
• Adventure Bay – near Captain Cooks Creek.

In both cases flooding is more likely with storm surge at high tides.

All waterways in the area are short, and so river gauges cannot provide sufficient warning. Flash flooding can impact:

• Roadways at low-lying river crossings, including the Channel Highway for short periods in some places, the Huon Highway near Sandfly and Sandfly Road
• 6 properties in Margate near Margate Rivulet or North West Bay Rivulet
• Several shacks near the mouth of Captain Cooks Creek at Adventure Bay, Bruny Island.

Some properties may become isolated for short periods due to flooding across roads. Debris can also be washed across roads, blocking access for longer times.

There are some low-lying shoreline areas that are at risk of coastal inundation.  Coastal flooding is more likely during storm events at high tide. Areas at most risk include:

• the Esplanade Dru Point, Margate and Barretta waterfront areas
• Snug foreshore
• Lower Snug/ Old Station Rd, Conningham
• Bruny Island Main Rd near Great Bay and the Isthmus
• Adventure Bay near Captain Cooks Creek
• Dennes Point Nebraska Beach, and some areas of the Bruny Island Main Road near Great Bay and the Isthmus.

Coastal erosion can also impact some areas. This is more likely during storm/ flood events.

See the Tasmanian Strategic Flood Maps to view the flood maps in more detail. To check if your property is at risk of coastal inundation or erosion see alert.tas.gov.au/get-ready/risk-ready/. SES is currently adding riverine flood maps to TasALERT risk-ready.

The maps in this guide show the level of flooding from rivers or coastal inundation that has at least a 1% chance of happening any year (climate up to 2016). You are likely to experience flooding such as that shown in the maps in your lifetime. Tasmanians need to prepare for flood events that may not happen often as well as the minor flooding they may have experienced. Even if your home is not flooded, you should be prepared for isolation plus potential power and telecommunications outages. Depending on where the rain falls and how heavy it is, other access roads may also be impassable. Travel in the area is likely to be difficult or impossible until roads are clear.  If you are safe at home or elsewhere, it is usually best you stay where you are until the flooding subsides, unless there is an emergency. If you need to evacuate, you should leave early, before flood waters rise.

您有洪水风险吗？

Aside from Snug river mouth and Adventure Bay near Captain Cook’s Creek, riverine flooding is not a concern for most areas around the Channel, but there is a long history of severe storms bringing heavy rain.  Severe storms causing storm water run-off and flooding issues happened, for example, in 1872, 1881, 1954, 1954, 1960, 1973, 1983, 1995, 1996, 2004, 205, 2010, 2011, 2015 and 2018.

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 – 个人和家庭应急准备指南。. 
• If you may be isolated and you must have access to services, you may need to evacuate early. Think about what you might need to take.

Floods like the one shown in the map will occur again. No two floods are the same.

If you live in a low-lying area or near a watercourse, your house may flood. Even if your home is safe, you may need to detour around flooded areas or your road access may be cut. Unless there are landslips, trees down or debris over roads, most areas are likely to only be isolated for a few hours.

Never drive into or enter flood waters. Roads and bridges may be washed out or unsafe. Avoid travel during floods.

Knowing what to do can save your life and help protect your property. Having a Home Emergency Plan is one of the best ways to prepare. See 做好应急准备 – A guide for individuals and households to prepare for emergencies. Decide on weather and rainfall triggers for when to act.

澳大利亚气象局天气预报、警告和观测

The Bureau issues a Flood Warning, Severe Weather Warning and/or Thunderstorm Warning for heavy rainfall that may lead to flash flooding whenever heavy rain is expected in an area. The time between the warning and heavy rain occurring can vary from an hour to 24 hours or more.

There are no river level flood warnings for any rivers in the area – the short catchment means river gauge information would not provide enough warning time.

Check 降水观测 at Mt Wellington / kunanyi, Margate, Dennes Point and other nearby rain gauges. Given the very short warning times, it is best to act on the predictive BoM warnings rather than wait for any flood alerts during rainfall.

这 Mt Koonya Radar is useful to be aware in real-time where heavy rainfall is falling.  Radar Rainfall estimates can also fill in gaps in areas where there are no rainfall stations.

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 and how wet the ground is beforehand and where the rain falls. Flooding is more likely at high tides around coastal areas. Weather systems producing heavy rain can also cause storm surge, coastal inundation and coastal erosion.

轻度洪水

Minor flooding can affect

• Some minor road river crossings
• Agricultural land on river flats
• Riverside parklands. Coastal parkland areas might also be affected at high tide.
• This level of flooding has about a 10% or more chance of happening any year.

中度洪水

A moderate flooding event can inundate riverside parklands and low-lying backyards and streets. Some homes and other buildings may start to be affected, particularly

• Brookfield near Margate and a couple of properties along Margate Rivulet
• Low-lying areas near Snug River mouth
• Some other low-lying areas near the coast and waterways

This level of flooding has about a 2-5% chance of happening any year.

Storm water, water and sewerage systems may be impacted.

特大洪灾

Major flooding with a 1% chance of happening could impact:

• Many properties around the mouth of the Snug River
• Some properties near Captain Cooks Creek, Adventure Bay, Bruny Island
• Some properties along North West Bay Rivulet and Margate Rivulet
• May mean some areas of Channel Highway and Bruny Island Main Road may be cut for a short time. Some areas may be isolated.
• At high tide there may be some extra areas also at risk of coastal inundation, such as:
• Margate Dru Point/ Esplanade and Barretta
• Snug foreshore, including areas around the Oval to the caravan park
• Lower Snug/ Conningham near Snug Creek and Old Station Road
• Kettering Marina/ Ferry Road area
• Woodbridge foreshore
• On Bruny Island, Dennes Point, various areas along Nebraska Beach
• Adventure Bay especially around Captain Cooks Rivulet
• Some sections of Bruny Island Main Road near Great Bay, the Isthmus and Alonnah.

了解风险，做好准备，尽可能降低风险，与他人联系，保持警惕，并安全行事。.

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

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。.

于

5. Keep up to date

留意周围发生的事情。定期查看预报、观测和警报。. 

• 塔斯警报 
• 您当地的ABC广播电台 或
• 这 气象局 网站.

6. Act Safe

• 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

• RSPCA 应急动物准备指南
• Huon Valley Council’s advice on preparing an emergency pet plan
• 这 初级生产者农场防洪准备工具包.

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。.
• 注意诸如
  • 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。.

之后

• 请继续收听 ABC 本地广播电台的最新消息、道路重新开放信息、社区会议等。.
• 如果您离开了家，在紧急事务管理署（SES）或塔斯马尼亚警方告知您可以安全返回之前，请勿回家。.
• 注意道路危险，例如路面上的泥土或碎屑、损坏的道路/桥梁以及正在进行清理和维修的工作人员。.

如果您的房屋遭到损坏

• 在检查损坏时，请留在地面。注意倒下的树木、碎玻璃、松动的屋顶或其他危险。.
• 穿结实的靴子、手套和防护服。. 
• 在受洪水影响的建筑物内部，请使用手电筒，切勿使用火柴或蜡烛。. 
• 饮用水必须煮沸，直到被告知自来水安全为止。.
• 在经过持证电工或燃气技师安全检测前，请勿开启电源或燃气。.
• 如果您的房屋受损，需要住到别处，请带上您的应急包和宠物。
• 如果安全，请拍摄任何损坏的照片并联系您的保险公司。.
• 看管好孩子。.
• 检查邻居是否安好。.

免责声明

The maps show potential flooding risks from consistent levels of rainfall across catchments, such as a 1% Annual Exceedance Probability (AEP).  In flooding events, rainfall is likely to be more inconsistent across a catchment, so these flood maps should be considered indicative only.  The mapped areas of flood risk show higher probability of inundation. Other areas have lower probability of flooding, but in severe and rare events (rarer than 1%AEP), other lower areas may be also at risk of inundation.
