A COASTAL low pressure cell developing over northern NSW has flood recovery officials looking closely at weather forecasts.
Clarence Valley Council deputy general manager Des Schroder said the forecast for the region worsened throughout yesteray.
"In the morning the forecast was for some rain, but close to the coast and no chance of flooding," he said.
"By lunchtime we were looking at the system coming further inland onto the ranges and 200mm of rain by Friday."
The Bureau of Meteorology's forecast for the region for the next week is cloudy and showers developing into general rain by the weekend.
Tabulam resident and retired meteorologist Steve Symonds said showers would increase to rain as a low pressure system continued to build off the coast, bringing possible wind gusts up to 50kmh until Thursday.
"This is normal type of weather for this time of year as the south- east trade winds push moisture through," he said.
Weatherzone predicted Thursday would bring with it the biggest rainfall, with a 90% chance of between 40mm and 80mm.
Temperatures should hover in the mid-20s for the rest if the week until things start to heat up at the weekend, with a top of 30 degrees predicted for Saturday.
So far this month Grafton has had 95.3mm of rain, creeping up to the long term February average of 147.8mm. The wettest day so far this month, February 2, filled the rain gauge with 49mm of water.
