SES preparing for wild weekend weather
THE Richmond-Tweed SES will have all hands on deck this weekend with another up to 90mm of rain predicted to hit the Northern Rivers on Sunday.
The Bureau of Meteorology says there is a 95% chance of rain of between 30 to 90mm.
Winds north to northeasterly 25 to 35 km/h increasing to 40 km/h before turning northwesterly 15 to 20 km/h during the evening are forecast.
Coming on the back of the recent flooding earlier this month, there are concerns of more damage.
But it is expected to be a fast-moving event which by Monday will have moved out of the region, eventually giving way to sunny skies mid-week.
SES region controller Andrew McPhee said the warning order had triggered a protocol to ensure it had extra staff on call.
"At the moment we're looking at the rain starting on Saturday, so we would certainly be having additional staff available over the weekend," Mr McPhee said.
"We're not tracking it at the moment as a severe as event as (the previous ECL on June 4) but that doesn't mean we're not taking it seriously.
"The picture from the BOM is it's not expected to impact the entire coast as last week's did, and it will be a shorter duration.
"But these systems are pretty dynamic."
"We obviously do our preparation for the worst case scenario. An East Coast Low is inherently unpredictable, it's a dynamic system - it could have an impact anywhere along NSW."
Mr McPhee also said any intense rainfall event into already wet catchments was a concern.
"We've been tracking the system for a couple of days already and our flood intel guys are looking at where the potential hotspots are should the current regime of rainfall eventuate," he said.
"If it falls over a very short period of time as it did last time we expect to see greater runoff because the catchment is already pre-loaded.
"High intensity rainfall falling over a short period of time (also) has the potential to cause flash flooding."
