FLOOD WATCH For the Mount Lofty Ranges district. Issued at 4:08 pm CST on Tuesday 8 July 2014 By the Bureau of Meteorology, South Australia. This Flood Watch is a heads up for possible future flooding and is NOT a Flood Warning. Weather Situation: A complex low pressure system with multiple centres and associated fronts will move across the south of the State during tonight and Wednesday. The first front is expected to affect the Mount Lofty Ranges in the next few hours, followed by a second front and low centre on Wednesday morning, and a third low centre Wednesday night. Another frontal system and rain band is expected on Friday. Rainfall : Showers and possible thunderstorms are forecast to develop across the Mount Lofty Ranges during the next several hours, then continue overnight and during Wednesday. Showers are likely to become frequent and locally heavy, particularly overnight and during Wednesday morning. Cumulative rainfall totals from Tuesday evening to midnight Wednesday in the Mount Lofty Ranges district are forecast to be in the range of roughly 25 to 60 mm, with possible localised higher falls. Flood Risk : As a result of recent rainfall up to 45 mm which fell between last Friday and Sunday morning, catchments in the Mount Lofty Ranges are quite wet, and therefore with the forecast rain, creek and river rises are expected. If rainfall intensity and totals turn out to be at the higher end of the forecast range, there is a risk of minor flooding in the middle and lower Torrens and upper and middle Onkaparinga catchments during Wednesday and also a risk of flooding in the Angus and Bremer catchments. People living or working close to rivers or creeks should monitor the latest weather forecasts and warnings and be prepared should flooding develop. Weather Forecast: For the latest weather forecast see bom.gov.au/sa/ Next Issue: This Flood Watch will be reissued by 4 pm Wednesday 9 July 2014.
