Sydneysiders are being warned to prepare for the wild, rainy weather that is expected to cause flooding in the city and elsewhere in New South Wales.

The Meteorology Department on Monday issued a flood alert and a severe weather alert with a low-pressure system that will likely clear heavy rains in coastal areas starting Wednesday morning.

Sudden floods, damaging winds and dangerous surfing conditions are expected. Anita Pyne, an analyst at the Bureau, said the strongest falls are likely to occur in Sydney and Illawarra districts, but the northern part of the South Coast, Central Coast and Blue Mountains can also be hit hard.

Most of the storm will end in a period of six to 12 hours from Wednesday morning.

Sydney and Illawarra are expected to receive up to 100 millimeters of rainfall with localized totals that can exceed 200mm, Pyne said in a statement.

The NSW SES warns that the Upper and Lower Nepean Rivers, the Hawkesbury River, the Colo River and the Georges and Woronora Rivers may experience moderate small floods.

The central coast, northern Sydney and southern Sydney can expect localized floods, such as the Upper Coxs River, the Macdonald River, the Parramatta River and the Illawarra Coast, which also provide for riverine flooding.

The SES has issued a warning to those living in potentially affected low lying areas to prepare for sandbag door flooding, ensuring gutters and sewers are free of debris and preparing for a possible evacuation.
