<\/figure>\n\n\n\nTo see the maps in more detail, see the Tasmanian Strategic Flood Maps<\/a>.<\/p>\n\n\n\n Storms often affect the D\u2019Entrecasteaux 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:<\/p>\n\n\n\n In both cases flooding is more likely with storm surge at high tides.<\/p>\n\n\n\n All waterways in the area are short, and so river gauges cannot provide sufficient warning. Flash flooding can impact:<\/p>\n\n\n\n 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.<\/p>\n\n\n\n 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:<\/p>\n\n\n\n Coastal erosion can also impact some areas. This is more likely during storm\/ flood events.<\/p>\n\n\n\n See the Tasmanian Strategic Flood Maps<\/a> 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\/<\/a>. SES is currently adding riverine flood maps to TasALERT risk-ready. <\/p>\n\n\n\n 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.<\/p>\n\n\n\n Go to tasalert.com or listen to ABC local radio 936AM for warnings and advice.<\/strong><\/p>\n\n\n\n Aside from Snug river mouth and Adventure Bay near Captain Cook\u2019s 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.<\/p>\n\n\n\n Floods like the one shown in the map will occur again. No two floods are the same.<\/p>\n\n\n\n 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.<\/p>\n\n\n\n Never drive into or enter flood waters. Roads and bridges may be washed out or unsafe. Avoid travel during floods.<\/strong><\/p>\n\n\n\n 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 Get Ready for Emergencies<\/a> \u2013 A guide for individuals and households to prepare for emergencies. Decide on weather and rainfall triggers for when to act.<\/p>\n\n\n\n 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.<\/p>\n\n\n\n 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.<\/p>\n\n\n\n Check Rainfall Observations <\/strong>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.<\/p>\n\n\n\n The Mt Koonya Radar<\/a> 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.<\/p>\n\n\n\n Keep aware of what is happening around you. Check forecasts, observations and warnings regularly.<\/p>\n\n\n\n\n
