UPDATE, 1pm: WEATHER experts have acknowledged there is a "lot of uncertainty" about the weather event that will hit the Northern Rivers over the next few days.
Weatherwatch meteorologist Anthony Cornelius said the weather system had an "unusual pattern".
"I'm calling this a hybrid low - but there's a case to say that it's just an East Coast Low too," he posted on his Facebook page.
"But I feel there's some tropical characteristics to this hence calling it a hybrid.
"In a nutshell - yes there's the potential this system could be fairly nasty, but we'll have to wait and see where things settle (so don't panic yet)."
