Strong winds continue to buffet South Australia today following the heaviest rain in more than a year in some parts of the state. A deep low pressure system centred west of Tasmania is directing vigorous winds, blustery showers and thunderstorms into the state's southern districts today. A severe weather warning was issued for damaging winds in central parts of the state this morning, including Adelaide and the Mount Lofty Ranges. Wind gusts earlier today reached 92km/h at Neptune Island, 82km/h at Mount Crawford and 72km/h at Port Lincoln. Showers and thunderstorms on Monday and last night brought more than 50mm of rainfall to some areas during the 24 hours to 9am today. The heaviest falls were in the Adelaide Hills, where Lobethal's 53mm was its heaviest rain in 14 months and the most for July in 19 years. Mount Barker saw its heaviest so far this year, with 34mm. Adelaide's 13mm was the city's heaviest rain in two months and brings the running monthly total to 64mm. If Adelaide reaches the long-term average of 78mm by the end of July, this will be its first wetter than average month since March. The recent rain has been a welcome change from last month, which was Adelaide's second driest June on record, with a meagre 8.6mm reaching the gauge. Conditions will ease across South Australia from tomorrow as the low moves across Tasmania and into the Tasman Sea. This calmer weather will lead to a cold night tomorrow, producing widespread frost across the state on Thursday morning.
