Queensland is set to be hit with a month’s worth of rain in a week, while widespread storms will drench parts of New South Wales from tomorrow into the weekend.
The Sunshine Coast is preparing for 200mm rain in a single day, with severe thunderstorms set to bring heavy falls in the coming hours.
Flood watch warnings are in place for the coastal catchments south of Maryborough to the NSW border and southern inland catchments.
A marine wind warning is also in place Sunshine Coast, Moreton Bay and Gold Coast Waters.
Gold Coast and Brisbane are also expected to be hit with 100mm and 50mm of rain, respectively.
Severe storms are expected to last until the weekend as a surface trough moving eastward combines with an upper trough over NSW.
Sydney will cop a drenching from tomorrow, with widespread heavy rain set for parts of NSW.
Upwards of 60mm of rainfall is expected for both Saturday and Sunday, which could cause potential major flooding.
Coastal parts of the state are being warned of hazardous surf conditions, with NSW police urging people to avoid rock fishing, boating, and swimming on the Hunter Coast, Sydney Coast, Illawarra Coast, Batemans Coast and Eden Coast.
Keeping out of shallow water and ocean bars is also recommended for boats, with those already on the ocean urged to “change or delay their voyage”.
The wet weather is tipped to head inland to drought-affected areas as far south as Canberra and to the fire-ravaged areas on the South Coast of NSW and East Gippsland in Victoria.
The bureau has described this as a major weather event, which has the potential to put out some of the 60 fires still burning across the state.
