Lismore and the Northern Rivers can breathe a collective sigh of relief as both the BOM and the NSW SES released positive weather news this afternoon.

The Bureau of Meteorology has cancelled the Severe Weather Warning which was forecast for the Northern Rivers, due to the previous risk of heavy rainfall deteriorating.

Despite this, the chance of isolated thunderstorms exists, with potential isolated heavy falls throughout Friday evening and Saturday for much of the North Coast of NSW. There is also the potential for minor flooding still for Wilsons River.

Superintendent (Supt) Joanna Jones stated, "We've had some improved news from the BOM today. They're saying that the weather system that you are seeing off the coast will move easterly and so we should see some reprieve from the rainfall as the weekend approaches."

Supt Jones said the larger falls of 240 to 270mm occurred in areas above Murwillumbah which did not have a large impact on river rises.

Many people would have received a text message from the SES very early this morning or saw it when you woke, Supt Jones said this was part of the Australian Early Warning System which is coming online at the end of the month.

"The reason we're doing that is because the community told us that we needed more timely and effective communication with them. So, when that severe weather warning for heavy rain, which could have led to flash flooding was broadcast, those text messages went out to alert the community that had been predicted by the BOM."

With a third La Nina now forecast this spring and summer, Supt Jones said this is a sign of what will be occurring in the future.

"We aim to inform the community in a timely manner and sometimes that will be early in the morning when we do get those predictions from the BOM."

While there were no evacuations from the effects of this weather system, Commander Richmond Police District Superintendent Scott Tanner said he gave the order to move sixty-six people in the forty-four motorhomes at the Lismore Caravan Park as a precautionary measure to Casino.

"As the Local Emergency Operation Controller, I've got overall responsibility for the safety and well-being of people and I think with what we were predicting yesterday certainly could have caused some issues if that CBD area had been impacted by flash flooding."

"At this stage we are in discussion with those residents and Resilience NSW about where is going to be the best place for those people to remain. I'm very conscious of the fact that I don't want to be evacuating them every couple of weeks because that's not good for anyone."

The weekend weather is for a possible shower tomorrow (Saturday) with 0-1mm predicted and a mostly sunny Sunday. Temperatures will be in around the mid-twenties.
