Severe Weather Warning: Heavy Rainfall says BOM – widespread along the coast and inland

Source: Bureau of Meteorology – issued at 5:00 pm Wednesday, 6 April

We’ve already got heavy rain across the Hawkesbury and the latest BOM weather update reinforces the wide geographical spread of the rainfall – see map below for the rainfall area.

The alert covers us in the Hawkesbury, with a warning for people in Sydney Metropolitan, Illawarra, South Coast and parts of Hunter, Central Tablelands and Southern Tablelands Forecast Districts.

HEAVY RAINFALL which may lead to FLASH FLOODING is forecast to develop about the Illawarra and parts of the South Coast and Southern Tablelands districts from this evening.

Rainfall will also extend into the Metropolitan and parts of the Central Tablelands and Hunter districts early Thursday morning. Six-hourly rainfall totals between 60 to 100 mm are likely, reaching up to 140 mm over coastal areas.

What’s causing the heavy rain:

A strong upper trough and embedded low is amplifying over central NSW. A coastal trough is forecast to deepen in response to this upper weather system and will remain slow-moving, producing areas of heavy rainfall. This coastal trough is forecast to weaken during Friday morning

At the moment a Flood Watch – but not a Flood Warning – is current for parts of southern and central New South Wales. For more details, please visit www.bom.gov.au/nsw/warnings.

Locations which may be affected by the heavy rain include Bega, Batemans Bay, Nowra, Goulburn, Wollongong, Sydney, Katoomba and Gosford.
