130mm of rain: Cyclone to bring three days of wild weather

WITH much of Queensland and parts of NSW in strife over major weather events we take a look to see what's in store for the Northern Rivers.

At the very least it'll be a good drenching of rain and at the worst it could be flash flooding, damaging winds, large hail and frequent "cloud to ground lightning".

The sodden and stormy conditions as a result of category three Cyclone Owen won't miss NSW, with warnings of "wild weather" continuing and the likelihood of heavy rain and thunderstorms across coastal areas, including the Northern Rivers, over the next few days.

The Bureau of Meteorology said a broad, slow moving low pressure system and associated trough over southwestern NSW was generating shower and thunderstorm activity throughout the state, however most of the activity is in the east ahead of the trough or near the low in the southwest.

Heavier showers and thunderstorms are expected to contract further east during today and Saturday, then to the northeast on Sunday.

Northern NSW Severe Weather forecasters said starting today we are entering a period where potential for Severe Thunderstorms is likely across parts of NE NSW.

They said conditions were "ripe" for severe storm development including supercells.

"Severe storms are likely to contain damaging wind gusts, large hail and heavy rainfall (flash flooding) not to mention large amounts of cloud to ground lightning.

"A few of these severe storms could become supercellular in which isolated destructive wind gusts and giant hail are possible. These should be far more isolated so the chances of being hit by one is lower."

BoM forecasts a very high chance of showers and thunderstorms from tonight through to Monday for the region.

Byron Bay and coastal areas could receive up to 20mm of rainfall tomorrow, 40mm on Sunday, and up to 50mm on Monday before conditions ease from Tuesday next week.

There's still good rainfall for inland locations with Lismore expecting up to 100mm from tomorrow to Monday and up to 80mm for Casino over these days.

Temperatures are also set to warm up and could reach 39C in Casino next Thursday.

"Thunderstorms by nature are very localised, quickly forming and moving over a location, so it is vital people remain aware of local conditions and closely monitor the warnings and radar from the Bureau of Meteorology" Forecaster Anita Pyne said.
