Residents of river catchment areas in the southwest corner of WA have been warned of potential flooding during a cold front expected to strike on Monday.
The Bureau of Meteorology has warned that flooding could occur on the Swan, Murray, Avon and Harvey rivers while issuing a severe weather warning from Geraldton to Esperance.
Heavy rain is expected to hit Monday evening as the storm passes through the lower western and southwestern districts, with a 30mm downpour expected before Tuesday.
Some areas along the Darling Range could display totals of up to 50-60mm.
The downpour could lead to rapid and sudden flooding in low-lying areas as well as river flooding and the forced closure of many main and secondary roads.
The storm at the start of the week could also cause widespread destructive winds averaging 60 to 70 km / h with maximum gusts to around 120 km / h – as well as unusually high tides and damaging waves.
The most dangerous winds are expected to develop around 2 p.m. southwest of a line from Bunbury to Bremer Bay – and could cause significant damage to homes or property.
“This front is expected to be windier than a typical front and is likely to produce the type of weather you only see about twice a year in southwest WA,” a spokesperson said.
The Department of Fire and Emergency Services has issued an official “Flood Watch” – warning people to prepare emergency kits with food and water, to fill fuel tanks, to move water. ‘equipment and livestock if they are near flood waters and monitor water levels.
People are also advised not to walk, swim, kayak, or play in flood waters – and not to park or camp next to rivers.
“Obey road closure signs and do not drive in water of unknown depth and current,” a spokeswoman said.
The flood warning comes after the southern WAW recorded its wettest July in decades, with rains throughout the southwest well above the year’s average.
From Claremont to Rockingham, the streets turned into mini-rivers as continuous cold fronts swept through the state.
Perth’s July record for precipitation is 425.1mm, recorded in 1958. This year’s deluge exceeded 212.80mm.
The supply to the Perth metro dam has already exceeded water levels last month, reaching 305.70 gigaliters and in cash. The entire month of June recorded 272.42 GL of water, according to the Water Corporation.
