Official storm warning for the Northern Rivers
UPDATE, 3.30pm: THE Bureau of Meteorology has issued a severe weather warning for parts of the Northern Rivers this afternoon.
Its website states: "Thunderstorm activity has temporarily eased, however further severe thunderstorms are still possible within the warning area during the next several hours which have the potential to produce damaging wind gusts and large hailstones."
Locations that may be affected include Casino, Coraki and Evans Head.
At 1.40pm, Coffs Harbour Airport recorded a 113km/h wind gust from a fast moving thunderstorm.
UPDATE 12pm: THE North Coast Storm Chasers have warned of the possibility of thunderstorms on their Facebook page.
"An approaching southerly wind change is causing the atmosphere to become unstable, with plenty of moisture around and decent steering winds in the upper atmosphere," Antonio Parancin from NCSC said.
"Unlike the past few days where storms stuck to the ranges and did not move much, today the storms will quickly march towards the E/NE and make it on the coast.
"If we get enough heating before the southerly change comes through Ballina/Lismore around 4-5pm we could be looking at storms becoming severe, especially on and east of the ranges and especially around Lismore, Ballina, Byron.
"It's almost perfect timing for a southerly, however because we have quite a bit of cloud cover there is that chance that we might just not be able to get the heating that is required for thunderstorms to become severe or decent, however it is very likely that we will see storms its still a question to ask if they will become severe.
"If you see some sunshine before storms and the temperatures reach or exceed about 27-29ºC there is a decent chance you will see a severe storm.
"So the purple areas is WHAT COULD happen if all the right conditions come into play, we will definitely see storms that's a promise that I can make this time."
