Australian Bureau of Meteorology (BOM) has issued new severe weather warnings for parts of southern Australia today, January 12, 2015.
After a week of severe bushfires, South Australia has been hit particularly hard by heavy rain which started affecting the country on Thursday, January 8, 2015. On January 9, BOM warned the state may see its heaviest statewide rainfall totals for a single event since 1974 and added fire danger ratings will continue to ease due to lower forecast temperatures and increasing humidity.
In their latest severe weather warning issued 04:49 UTC today (15:49 EDT) for Victoria, BOM said a low pressure trough will enter western Victoria on Tuesday morning, January 13, and move only slowly eastwards into central districts by Tuesday evening as an associated low pressure system deepens and moves over western Bass Strait.
Heavy rain and thunderstorms which may lead to flash flooding are forecast for parts of the Mallee, Wimmera, Northern Country, North Central, North East, South West and Central forecast districts on Tuesday.
Heavy rainfall is likely to develop over western districts during the morning and extend into central districts by midday then contracting to the northeast during the afternoon before easing by the evening.
The State Emergency Service (SES) advises that rainfall run-off into waterways in recent fire affected areas may contain debris such as soil, ash, trees and rocks. People in fire affected areas should also be alert to the potential for landslide and debris across roads.
BOM is predicting overnight falls of up to 20 mm in the Adelaide metropolitan area and falls of between 30 and 35 mm in the Mount Lofty Ranges.
A severe thunderstorm warning for heavy rainfall was issued for people in the Flinders and North East Pastoral districts of South Australia at 08:18 UTC (18:48 CDT):

At Leigh Creek Airport, 55 mm was recorded between 3:15 pm and 6 pm this afternoon (local time), with 30 mm in 45 minutes.
