A deep low pressure system and an associated trough have triggered record rainfalls in the South West district of Victoria overnight. The system left 71.2mm at Portland making it their highest 24 hour total in June since at least 1982. This total was also the highest 24 hour rain out of any month since January 2011, and better resembled monthly totals experienced through the autumn months. Cape Nelson had its wettest June day since at least 1996, with 53mm falling to 9am. Warrnambool also had their wettest June day since 2005 gaining a notable 30mm overnight and their highest daily total out of any month since October last year. Showers may continue this afternoon for the South West district, although contracting east and south. Tomorrow, cloud will be a major feature with a few isolated showers about southern areas. This pattern is expected to continue throughout the start of the working week.
