Update, 5pm: LOCAL emergency services workers and volunteers have been run off their feet as the south-west battles a "one in 10 year" rain event. Allansford community members will provide sandbags to residents as a "precaution" following flash flooding with more rain forecast tonight. Allansford Recreation Reserve member Eddie White said he was "concerned" the Hopkins River and Emu Creek could overflow and cause flash funding on Thursday night. "If they both come up like they did in 2011, we will need the sand bags," Mr White said. "I don't know how many houses will take it. I imagine a lot of the low-lying houses will." He said Warrnambool City Council had provided the sand and bags, with volunteers helping to prepare the bags from 5pm at the recreation reserve. "If I can get five or 20 people there tonight we shouldn't have to be there at two in the morning," Mr White said. Footage on Thursday afternoon shows a raging Hopkins Falls. Bureau of Meterology senior forecaster Tom Delamotte described the downpour as a one-in-10-year event for Warrnambool. "The rainfall total over a nine-hour period was at a rate you only see once every 10 years," he said. Mr Delamotte said the weather was expected to start to clear on Friday. The Bureau of Meterology has issued flood warnings for Casterton. Minor flooding may develop at Casterton during Thursday afternoon. Further rises around the minor flood level are expected on Friday. In the 24 hours to 9am Thursday, widespread rainfall totals of 30-35 mm have been recorded in the Glenelg catchment. A further 20-30 mm of rain is forecast for the remainder of Thursday. The Glenelg River at Casterton is currently at 3.56 metres and rising and may reach the minor flood level - 3.80 metres - Thursday afternoon. Further rises are possible on Friday with the arrival of the flood waters from Dergholm. A low pressure system near the southwest coast of Victoria will move gradually eastwards across Bass Strait today and Friday. Damaging westerly winds, averaging 50 to 60 km/h with peak gusts of 90 to 100 km/h, are expected to develop about the southwest and the central ranges this afternoon, extending to the central coast and southwest Gippsland later tonight. While showers will continue over Victoria, particularly over the eastern ranges and the southwest, the risk of heavy rainfall which may lead to flash flooding has eased and the warning for heavy rainfall has been cancelled. SES advises that all community members should: Warrnambool Police have been busy staffing the Police Operations Centre in support of today's flood response with the SES. "Looks like the rain is here to stay today folks. Please avoid the roads if you can and be vigilant of the conditions. Stay safe," police posted on social media. Earlier, 10.50am: AN ALLANSFORD resident whose rental property has flooded for the second time in two weeks following heavy rain says street drainage needs to improve. Ziegler Parade resident Carol McKenna and husband Owen found flood waters had surrounded the home during heavy rain late Wednesday. Emergency services, including Warrnambool SES and Allansford CFA, worked through the night to pump water from the street and affected properties. "The flood waters were all the way around the house," Ms McKenna said. "It was past our house and maybe four or five houses down as well." It's the second time in less than two weeks the street has flooded, affecting the McKenna's home twice. "We are really disappointed with the council that they haven't done anything as yet," Ms McKenna said. "It could happen again with the weather we are expecting. We had sandbags around the back, around the front door and along the guttering." Warrnambool City Council said staff worked through the night to check drains. EARLIER: Emergency services worked through the night to respond to multiple floods as heavy rain hit the Warrnambool district. State Emergency Services responded to 12 calls for assistance in Warrnambool and eight in Port Fairy, mostly for flooding issues. SES Warrnambool controller Giorgio Palmeri said there were "several floods" overnight. "The one that took the majority of our time and crews was in Allansford, where several premises were affected by flood in the front yards," Mr Palmeri said. "There was no damage to property, we were able to work with the Allansford CFA and pump water from the front of those premises away. "There were some obstructions in the drains that council is working on." He said multiple crews worked from 11pm on Wednesday until about 7am on Thursday morning. The Bureau of Meteorology has recorded 55.6 millimetres of rain falling in Warrnambool since 9am on Wednesday. Mr Palmeri said crews were responding to flooding that had reached inside a home in Yangery on Thursday morning. "There is more rain coming. People should make sure they are careful, try not to drive through flood waters as always, stay away from trees and secure things around the house," he said. Crews also responded to flooding at Woolsthrope, Mailors Flat and Monterey Court in Warrnambool near Russells Creek overnight. Dennington resident Naomi Harvey woke to flooding on Farmham Road on Thursday and kept the family home. "I took the kids down 7.30am and said I don't think 'we are going to school today'," Ms Harvey said. "I just don't feel confident driving across flood waters. You can't seen underneath flood water. It's a wise decision." Have you signed up to The Standard's daily newsletter and breaking news emails?
