FARMER Sam Hyatt of Glenreagh has a method for predicting the weather.
"Whatever the man on the radio said the weather was going to be, I just said it would be the opposite," Mr Hyatt laughed.
"I tell you I reckon I was right just as often as he was."
However, as the Bureau of Meteorology predicted a low pressure system bringing over 300mm of rain this Friday for areas of the Clarence Valley, Mr Hyatt said it was exactly the sort of conditions that would lead to it.
"Years ago, it was always the cyclones that came down the coast that would bring the heavy dumps of rain," he said.
"Now it's the East Coast lows that really bring the big downpours, so if there's one out there I'd say we're in for some."
The predicted rain would be bad news for the farming community Mr Hyatt said, with the heavy rains likely to sour what was good grass cover.
"Conditions have been really good, we had a bit of flood rain that's put some moisture into the subsoil," he said.
"But with that sort of rain, it turns the grass into mush and just destroys it."
The one thing that Mr Hyatt was certain of was the uncertainty of recent weather.
"It's been very unpredictable, for much of last year we had very drought-like conditions where we had absolutely no water."
"Now we've had good rain and we're looking at too much.
"You just can't pick it."
The Bureau's modelling shows a low off the north-eastern coast of Australia moving south and starting to bring heavy rain from Thursday.
On Friday, their rain forecast predicts falls in the coastal areas of more than 300mm, which is more than double the mean rainfall for the area for February.
Heavy winds and large swells will accompany the rain front in coastal areas.
The rain will continue on Saturday, with predictions of between 25-50mm of rain for the area.
