Flood Watch – Hawkesbury, Lower Nepean and Colo Rivers set for minor to moderate flooding – BOM

Released 10.37am by Bureau of Meteorology

This is a BOM Flood Watch rather than a specific Flood Warning, so it’s a keep-an-eye on it situation at the moment. In our area, catchments likely to be affected include: Upper Nepean River moderate to major flooding Hawkesbury and Lower Nepean Rivers minor to moderate flooding Colo River minor to moderate flooding Macdonald River – no warning yet What’s happening? A slow moving coastal trough lies off the northern NSW coast. Later on Tuesday a low pressure system will form within this trough before moving towards central parts of the NSW Coast and deepening into an East Coast Low. Heavy to torrential rain is likely to the south of the low affecting Sydney, Illawarra and the South Coast from later on Tuesday. Catchments remain wet, with many NSW dams near capacity. A Severe Weather Warning for heavy to locally intense rainfall has been issued for Greater Sydney, Central Coast, Illawarra and South Coast and parts of adjacent districts. The weather system is expected to cause riverine flooding for the parts of the Mid North Coast today and extend further south to the Central Coast, Sydney, Illawarra and South Coast catchments from later on Tuesday. Flood classes (minor, moderate, major) are only defined for catchments where the Bureau provides a flood warning service.

Flood Warnings will be issued if Minor Flood Level is expected to be exceeded at key sites along the main rivers for which the Bureau of Meteorology provides a flood warning service. Severe Weather Warnings will be issued or updated if very heavy rain is forecast or observed.
