Rain threatening to flood SA

Widespread fall of 20-to-50 millimetres are set to drench much of South Australia during the next few days with potential for more than 50mm in parts, leading to some flooding.
Rain developed during Saturday and will become more widespread and increase during Sunday and Monday as a slow-moving low pressure trough taps into moisture from the northwest tropics.
All districts apart from those in the far south and far north are likely to be substantially affected with the heaviest falls likely north of Adelaide.
Almost all of the state is having a wetter than normal summer-to-date with parts of the north and west receiving more than three times their December-January average.
Adelaide is already having its wettest summer-to-date in 54 years and third wettest summer-to-date on record, gaining 134mm so far, about 90mm more than the December-January average.
In the Mid North where some of the heaviest falls are likely in the next few days, Snowtown is having its wettest summer-to-date in about 130 years of records. It has had 175mm so far, about 140mm more than average.
SA will begin to dry out during Monday and be almost totally dry on Tuesday and Wednesday with help from a high pressure system taking over but humidity will remain fairly high for a few days. This will maintain the risk of disease in the state's maturing grape crop as vintage nears.
