SA ends autumn with a drenching

Rob Sharpe, Saturday May 31, 2014 - 11:15 EST

South Australia will see rain ease back today after an overnight soaking that targeted the Flinders Ranges.

A low pressure system slowly moving across SA brought heavy rain and storms overnight. The wettest location was Hawker, which amassed 41mm. This was its wettest May 24 hour total in 14 years. The ranges as a whole saw totals generally of 20-40mm.

In the south, Port Lincoln recorded its wettest May day in 19 years of records for the second time this month with 29mm. The coastal town has now set a new benchmark for its wettest May with 89mm.

Today, the band of rain will continue edging further south, focussing on and near the Mt Lofty Ranges and Yorke Peninsula. This afternoon isolated thunderstorms will develop north of the rain band across the east of the state and into the Eastern Eyre Peninsula. Storms should only produce isolated totals over 10mm.

From tomorrow South Australia will be much drier as a high pressure system starts to take over the weather pattern. It should be at least two weeks before a bout of heavy rainfall spreads across the state.

Thankfully for farmers, almost the entire state picked up near or above average rainfall through autumn. This will hold many in good stead as a drier than usual winter is likely to kick off tomorrow. The reason for this is that El Nino is likely to take hold in the Pacific and the Indian Ocean Dipole should be in either a neutral or positive phase. These two climate drivers both tend to bring drier than usual winters in South Australia.
