BOM reported a strong high pressure system over the southern Tasman Sea and a broad trough over Queensland are combining to produce a humid easterly airflow and widespread rain over eastern NSW. A trough has been forecast to deepen along the northern NSW coast during January 5 under the influence of an approaching upper level feature that will produce heavy rainfall in the Hunter and Mid North Coast districts.

A severe weather warning was issued for northern and southern parts of NSW, including the Mid North Coast, Hunter, Illawarra, South Coast, Southern Tablelands and Snowy Mountains.

Many famous beaches across the state have been closed due to dangerous surf conditions. Tamarama area also reported high pollution levels caused by heavy rainfalls and overflowing storm water. 1 person died in flood-related incident near Seymour on January 4, according to media reports.
