AUTHORITIES say another thunderstorm warning for the Northern Rivers is imminent, following a severe storm which battered Casino overnight.
Roofs collapsed and trees came crashing down, as a short burst of thunderstorms and damaging winds hit the region on Saturday, from 11pm.
About 250 residents in Rappville, Whiporie and areas south of Grafton, remain without power on Sunday, as Essential Energy continue repairs to damaged power lines.
A Bureau of Meteorology spokesperson said a severe weather warning for the entire Northern Rivers region, from Kempsey to the NSW-Qld border is likely to be issued today, following last night's storm activity at Casino.
"There was a trough moving through the area, with a high amount of moisture and an unstable environment, and all those factors contributed to the severe thunderstorm," he said.
After surges of gale winds, lightening and rain at Casino, SES, NSW Police and the Rural Fire Service removed dangerous debris from the roads.
Rappville Rd, Ellangowan Rd and Summerland Way were cut off by several large fallen trees, ripped from their roots.
Properties were also damaged.
A mill in Rappville lost its roof and Jill Francis of Tallowwood Rd, reported that a damaged roof inside her rental property broke during the storm.
