5.14am: THE Bureau of Meteorology has issued a new severe weather warning for the Northern Rivers even as a flood warning issued yesterday is about to expire.
In the new warning, issued this morning, the Bureau warns the weather station at Cape Byron has today already recorded wind speeds averaging around 74km/h while the Yamba station had recorded winds averaging around 69km/h.
The severe weather was being caused by a deep low off the Queensland coast which, through the remainder of the morning, was expected to cause damaging winds around the region this morning averaging around 70km/h but gusting up to 90km/h.
The good news was the low pressure system was moving slowly away from the south Queensland coast while a high system moving over central NSW meant the winds were expected to ease this afternoon.
A flood watch on the Wilsons River at Lismore is expected to expire at 6am although rain is expected to continue through the day, particularly along the coastal strip. The Bureau predicts the rain will ease further tomorrow before disappearing entirely on Thursday.
Top temperatures today were expected to range between 19 and 20 degrees Celcius.
