Update 4.30pm: NORTH Coast towns have avoided major damage as a severe storm passes through the region.
Richmond-Tweed State Emergency Service regional controller Mark Somers said volunteers have responded to nine jobs across the region since the storm hit.
The most recent of which he said were SES volunteers are working with contractors at Bailey St, Rappville to respond to a number of trees threatening to fall in the area.
If needed, Mr Somers said volunteers from the Woodburn unit may be deployed to assist the MacLean, where volunteers are responding to about 60 call outs.
Based on the latest weather information, Mr Somers expected the storm to ease soon and described the weather as a "typical storm for this time of year".
The Lismore SES unit are reporting water over the road in parts of Lismore.
They said there were reports of water over the road at the Dawson / Zadoc Streets roundabout.
They said the situation was caused by flash flooding in the basin area (ovals in front of the square) and usually receded quickly.
There are also reports of water on Wyrallah Road at the intersection with Esmonde Street in East Lismore.
The SES advise you should avoid driving in these areas.

Original story 11am: WEATHER forecasters say it will be another big day for storms, and have warned people to stay away from lightning after reports of "close calls" yesterday.
Antonio Parancin, a weather forecaster from North Coast Storm Chasers, said today's conditions were "almost a direct copy of yesterday's conditions".
"Thunderstorms are expected to develop after lunch and then quickly strengthen into severe storms that may become supercells and track in a general NE direction," he posted on Facebook
"This is exactly what happened yesterday when a severe supercell tracked from south of Yamba all the way through Ballina and Byron Bay delivering giant hailstones and destructive winds.
"Today my personal hot spot for severe activity is from Coffs to Casino to Ballina to Byron and all surround areas."
Severe thunderstorms that develop today are likely to contain:
- Damaging / destructive winds
- Large to giant hailstones
- Intense rainfall and reduced visibility
- Flash flooding
- Frequent lightning
- Green in clouds (hail present).
Mr Parancin said the storms would not take long to fire up and gain strength.
"Some things to mention: Do not park you car under a tree because if a branch snaps and hits your car it will be worse than if hail had affected it, instead bring out the doona if you must," he wrote on Facebook.
"Do not stand outside when active lightning is occurring, yesterday we had many reports of very close calls, you don't want to be barbecued."
