Riverine and flash flooding information for areas between Barossa Creek and Islet Rivulet, including Humphries Rivulet and surrounding minor waterways.

Understand your flood risk and get ready

Parts of Glenorchy city and suburb and Montrose are at risk of flooding from

Barossa Creek
Humphries Rivulet
Islet Rivulet and
minor waterways in between.

The area is a floodplain, which means it is a high-risk area for flooding.

It is important you understand what a flood can look like in your area so you can be prepared. You are likely to have a flood that causes significant damage in the area at least once 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.

Glenorchy and Montrose are prone to flash flooding, depending on how rain falls across Kunanyi/ Mount Wellington. This means there can be little warning before waterways flood. There can also be stormwater run-off in other places if there is heavy rain. This can be difficult to predict.

Flooding may isolate parts of Glenorchy for up to 6 hours but is more likely to be for just a few hours. You should prepare for isolation plus power or telecommunications outages.

Some roads around Glenorchy and Montrose may flood. Traffic is likely to be congested. Travel may be difficult or impossible. If you are safe at home or somewhere else you are at the time, it is usually best you stay there until the flooding goes down. If you need to leave during a flood, make sure your route is safe. If your home could become flooded, it is a good idea to think about

where you would go, and
how you could get there.

您有洪水风险吗？

Past flooding events around Glenorchy include:

May 2018 – The Southern Tasmanian Extreme Weather Event caused flooding around Hobart. There was 236mm of rain on Kunanyi/ Mount Wellington.
April 1960 – About 200mm of rain fell over 3 days causing damage across Hobart.
June 1947 – Two separate flooding events impacted Glenorchy and Montrose.

What should I do to prepare?

Check the map to see whether your home or business is at risk of being flooded. If it is, you should have a plan for leaving during a flood event. For example, you might go to nearby family or friends who are not at risk of flooding. During a flood event, go to TasALERT.com or listen to ABC local radio to find out about evacuation centres or other places to shelter.
Check if you can safely get to your home, work, or school during a flood. If you need to leave during a flood, make sure your route is safe or leave early before floodwaters rise.
Prepare your home or business to minimise possible flood damage.
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 have a business in the area, you should have a plan that covers flooding – see www.business.tas.gov.au.

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

如果您住在低洼地区或靠近水道，您的房屋可能会被淹没。即使您的家是安全的，您也可能需要绕过洪水地区，或者您的道路通行可能会受到阻碍。切勿驾车进入或进入洪水区域。道路和桥梁可能被冲毁或不安全。请避免在洪水期间出行。.

了解该怎么做可以拯救你的生命并帮助保护你的财产。制定家庭应急计划是准备工作的最佳方法之一。决定天气和降雨触发条件，以便知道何时采取行动。.

澳大利亚气象局天气预报、警告和观测

Whenever 大雨 is expected in an area, the Bureau issues

a Flood Watch
Severe Weather Warning and/or
Thunderstorm Warning for heavy rainfall that may lead to flash flooding.

The time between the warning and heavy rain falling can vary from an hour to 24 hours or more. It is best to act on the warnings from the Bureau of Meteorology rather than wait for local flooding alerts.

Tracking Rainfall on Kunanyi/ Mount Wellington can help predict flooding around Glenorchy and Montrose.

这 Mt Koonya Radar is useful to see when and where heavy rainfall is falling.

理解警告和关键信息

Keep aware of what is happening. Check forecasts, observations and warnings regularly.

Flood levels around Glenorchy city and suburb

how heavy it is
how long the rain lasts
how wet the ground is beforehand
how full dams are, and
where the rain falls.

Minor flooding may impact

some low-lying areas, around Grove Road,
some sections of the intercity cycleway and foreshore areas at high tide.

While most people will be safe at home until flood waters go down, those around Grove Road, Glenorchy CBD and south of Barossa Creek can move away from flooding towards the Showgrounds and Dowsings Point if needed.
Those north of Barossa Creek and south of Islet Rivulet are likely to be isolated for some hours until flood waters go down. Listen to ABC local radio or go to TasALERT.com for advice on where to go if you need to leave your home.

Unless there is an emergency or you are not safe where you are, you should shelter where you are during a flooding event. Floods around Hobart rarely last more than a few hours. Traffic is likely to be very congested. Listen to ABC local radio or go to 塔斯警报 for advice.

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。.

Check your plan regularly and test that everyone in the household understands what would need to happen in a flood.

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
– insurance papers
– passports and
– birth certificates

定期测试收音机和手电筒里的电池。.

3. Reduce your risk from flooding where you can

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. Connect with others

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。.

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

Avoid travelling during and after storms

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.
