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.

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.
Sediakan Pelan Kecemasan Rumah. Lihat Bersedia untuk Kecemasan – Panduan untuk individu dan isi rumah bersiap sedia menghadapi kecemasan.
If you have a business in the area, you should have a plan that covers flooding – see www.business.tas.gov.au.

Banjir seperti yang ditunjukkan dalam peta atau lebih teruk akan berlaku lagi. Tiada dua banjir yang sama.

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

Mengetahui apa yang perlu dilakukan boleh menyelamatkan nyawa anda dan membantu melindungi harta benda anda. Mempunyai Pelan Kecemasan Rumah adalah salah satu cara terbaik untuk bersiap sedia. Tentukan pemicu cuaca dan hujan untuk masa bertindak.

Bureau of Meteorology Forecasts, Warnings, and Observations

Whenever heavy rain 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.

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

Sebelum banjir

Ketahui risiko anda

Banjir sering berlaku di Tasmania dan boleh menyebabkan kerosakan yang meluas dan ketara. Dalam tempoh 200 tahun kebelakangan ini, terdapat 78 kematian berkaitan banjir di Tasmania. Panduan ini adalah untuk membantu anda memahami risiko banjir di kawasan anda.

2. Sediakan rumah anda

Miliki pelan kecemasan yang meliputi taufan dan banjir

Berfikir tentang apa yang akan anda lakukan semasa ribut atau banjir bermakna anda lebih bersedia dan semua orang lebih selamat. Miliki pelan kecemasan yang difahami oleh semua orang dalam isi rumah anda. Terdapat senarai semak untuk membantu anda memikirkan pelan anda – lihat Bersedia untuk Kecemasan – Panduan untuk individu dan isi rumah bersiap sedia menghadapi kecemasan.

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

Sediakan Kit Kecemasan

Sedia untuk Pergi

Radio berkuasa bateri dan lampu suluh, bateri ganti

Maklumat penting, seperti pelan kecemasan anda

Senarai nombor kecemasan

Makanan dan air

Peti pertolongan cemas

Sarung tangan getah atau kulit asli yang kukuh

3. Kurangkan risiko anda daripada banjir di mana anda boleh

Pertimbangkan tentang ribut, banjir dan bahaya lain semasa membeli, menyelenggara atau membangunkan hartanah.
Potong atau alih pokok dan dahan yang menjulur ke atas rumah, perniagaan anda atau berdekatan talian elektrik di kawasan anda.
Pastikan saluran air dan perparitan anda bersih.

4. Berhubung dengan orang lain

Kenali jiran anda dan libatkan diri dalam komuniti anda. Komuniti yang saling berhubung adalah komuniti yang lebih selamat dan lebih berdaya tahan semasa kecemasan dan dapat membantu semua orang pulih dengan lebih baik selepas itu. Periksa sama ada keluarga dan jiran selamat dan sedar tentang apa yang berlaku.

Semasa

5. Sentiasa terkini

Sentiasa peka dengan apa yang berlaku di sekeliling anda. Periksa ramalan, pemerhatian dan amaran dengan kerap.

6. Bertindak Selamat

Mengawasi kanak-kanak.
Bersiap sedia untuk kemungkinan gangguan bekalan elektrik, air atau internet.
Pastikan peti kecemasan anda bersedia untuk digunakan.
Jauhi kawasan yang dinaiki air seperti longkang. JANGAN SESEKALI berjalan, bermain, menunggang atau memandu dalam air banjir. Anda tidak selalu dapat melihat apa yang ada di bawah air atau betapa dalamnya atau derasnya air itu. Sangat mudah untuk dihanyutkan dan lemas dalam air yang bergerak pantas sedalam 20sm. Air banjir boleh berbahaya.

Bila rumah anda mungkin dinaiki air

Letakkan barangan isi rumah di tempat yang tinggi untuk meminimumkan kerosakan yang mungkin berlaku.
Padamkan bekalan elektrik dan gas jika selamat untuk berbuat demikian.
Cara yang baik untuk menghentikan aliran kumbahan masuk semula ke rumah anda ialah dengan meletakkan beg pasir di dalam beg plastik dan menggunakannya untuk menyumbat tandas serta menutup longkang dan singki.
Pergi selagi anda boleh keluar dengan selamat.

Jika anda perlu berpindah

Ikuti nasihat dari SES / Polis Tasmania.
Ambil kit kecemasan anda.
Pergi ke tempat rakan atau keluarga yang lebih selamat atau pusat pemindahan.
Beritahu orang lain ke mana anda telah pergi.

Jaga haiwan peliharaan anda

Anda bertanggungjawab terhadap haiwan anda semasa kecemasan. Sekiranya anda mempunyai haiwan peliharaan dan haiwan lain, anda akan mengambil masa lebih lama untuk berpindah sekiranya berlaku banjir atau kecemasan lain. Pindahkan ternakan dari kawasan yang terdedah kepada banjir **jauh sebelum** paras air banjir mungkin naik. Untuk maklumat lanjut, sila lihat

Elakkan perjalanan semasa dan selepas ribut

Jangan melancong. Pelancong melambatkan perkhidmatan kecemasan dan menyebabkan kemalangan.
Berhati-hatilah terhadap bahaya seperti
- air di atas jalan
- talian elektrik rosak
- tanah runtuh
- jalan rosak
- pokok tumbang atau bumbung besi.
Jangan memandu melalui air banjir. Kebanyakan kematian dan penyelamatan dalam banjir disebabkan oleh orang yang memandu melalui air banjir.
Pandu perlahan dan pasang lampu hadapan anda di jalan yang tidak dinaiki banjir.

Selepas

Terus ikuti perkembangan terkini dari ABC Local Radio, pembukaan semula jalan, mesyuarat komuniti, dll.
Jika anda meninggalkan rumah anda, jangan pulang ke rumah sehingga SES atau Polis Tasmania memberitahu anda selamat untuk berbuat demikian.
Berhati-hatilah terhadap bahaya jalan raya, seperti lumpur atau serpihan di jalan, jalan/jambatan yang rosak dan kru yang sedang bekerja membersihkan dan membaiki.

Jika rumah anda rosak

Tinggal di aras tanah semasa memeriksa kerosakan. Berhati-hatilah dengan pokok tumbang, kaca pecah, bumbung yang longgar atau bahaya lain.
Pakai but kuat, sarung tangan dan pakaian pelindung.
Gunakan lampu suluh, jangan gunakan mancis atau lilin di dalam bangunan yang dinaiki banjir.
Rebus semua air minuman sehingga anda diberitahu air paip selamat semula.
Jangan hidupkan bekalan elektrik atau gas sehingga ia diuji oleh juruelektrik atau pemasang gas bertauliah bagi memastikan keselamatan.
Jika rumah anda rosak dan anda perlu menginap di tempat lain, bawa bersama kit kecemasan dan haiwan peliharaan anda
Ambil gambar kerosakan jika selamat untuk anda berbuat demikian dan hubungi syarikat insurans anda.
Mengawasi kanak-kanak.
Periksa jiran dalam keadaan baik.

Penafian

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.
