THE Bureau of Meteorology issued a severe weather warning for the Mid North Coast this afternoon.
A slow moving low pressure trough off NSW coast and an upper cold pool will continue to generate heavy rain locally tonight and Thursday.
Conditions are expected to ease on Thursday but heavy rain could cause flash flooding.
On Tuesday night 35.8mm of rain fell on Coffs Harbour in the space of six hours prior to midnight.
The rain on the ranges, river valleys and water catchment areas was not as heavy which meant that there was no escalation of flood watches on the Bellinger and Orara Rivers to actual flood warnings.
Heavy rain could change that situation and the Bureau of Meteorology is keeping on eye on a storm front that has been building 30km east of Coffs Harbour that is capable of bringing heavy rainfall overnight.
