South Australia braces down for strong winds, heavy rainfall and isolated thunderstorms this evening. A low pressure system residing over the Bight is due to move on shore this afternoon and evening, causing conditions to worsen. Exposed coastal locations across the Yorke and Eyre Peninsula's in addition to Kangaroo Island and Neptune Island have already clocked max gusts upward of 60 km/h this earlier this afternoon, but are bracing for strengthening gusts. The strongest winds are expected along western quadrants of this system and have the potential to steer gusts near 100 km/h over parts of Kangaroo Island, the Yorke Peninsula, Lower Eyre Peninsula and the Fleurieu Peninsula during the late afternoon and evening. Further inland, winds are expected to be lighter, but gusts of 60- 80 km/h are still a chance over the Eastern Eyre Peninsula, Mt Lofty Ranges and metropolitan Adelaide. Embedded thunderstorms are a significant risk with this system, likely scattered among showers and cloud. These storms are most likely to extend from Kangaroo Island to the Flinders and far southern parts of the North East Pastoral and Murraylands where small hail is a chance. The heaviest rainfall looks to be confined to the coastal fringe of the Upper and Lower South East where 20-40mm has the potential to accumulate. The Bureau of Meteorology has issued a severe weather warning, alerting for damaging winds and heavy rainfall.
