STORM IS COMING: The entire Northern Rivers will be impacted

UPDATE, 4.10pm: THE latest weather update shows severe thunderstorms are still on the way, but we may be waiting an hour or longer.

The Bureau of Meteorology has reported severe thunderstorms likely producing large hailstones, heavy rainfall and damaging winds over the next several hours.

The bureau reports the affected areas on the Northern Rivers have widened to include the whole of the Northern Rivers, including Lismore, Casino, Kyogle and coastal cities up to the Queensland border.


UPDATE, 1.35pm: AN OFFICIAL severe thunderstorm warning has been issued for the Northern Rivers this afternoon.

The Bureau of Meteorology has reported that "severe thunderstorms are likely to produce large hailstones, heavy rainfall that may lead to flash flooding and damaging winds in the warning area over the next several hours".

Areas that may be affected include Casino, Kyogle, Lismore and other inland areas.

The State Emergency Service advises that people should:
• Move your car under cover or away from trees.
• Secure or put away loose items around your house, yard and balcony.
• Keep at least 8 metres away from fallen power lines or objects that may be energised, such as fences.
• Report fallen power lines to either Ausgrid on 131 388, or Endeavour Energy on 131 003 or Essential Energy on 132 080, as shown on your power bill.
• Keep clear of creeks and storm drains.
• Don't walk, ride your bike or drive through flood water.
• If you are trapped by flash flooding, seek refuge in the highest available place and ring 000 if you need rescue.
• Unplug computers and appliances.
• Avoid using the phone during the storm.
• Stay indoors away from windows, and keep children and pets indoors as well.
• For emergency help in floods and storms, ring the SES (NSW and ACT) on 132 500.

UPDATE, 11.55am: "STORM likely" is how the Bureau of Meteorology's Lismore forecast looks right now, but no warnings are in place.

Weatherzone, which uses BOM data, predicts a 90% chance of rain which is most likely to fall around 3pm.

There's also a lot of storm talk going around Facebook sites.

"Today will see the potential for storms to develop throughout the Northern Rivers district," Peter from the Tweed/Byron & Murwillumbah Weather and Information Exchange said.

"Some storms do have the potential to become severe throughout this afternoon.

"Main threats will be hail, possibly large, strong to damaging winds and heavy rainfall which may lead to localised flash flooding."

The storm chasers wrote on their page "we have a few things to take into consideration before we get too hyped about them (storms)".

They wrote that some cloud cover could delay storm development and the severity of the storm depended on a weak southerly change which pulled through overnight.

"It is currently sitting around the NSW/QLD border and is stalled," they wrote.

"Models suggest that NE winds ahead of the change will strengthen and push the southerly back south if not wash it out."

They wrote if this occurs there is a high chance of a severe storm particularly around Nimbin and Kyogle and there's a good chance of seeing some storms in other Northern Rivers areas.


ORIGINAL STORY: IF the predictions are anything to go by, the Northern Rivers is in for some interesting weather today.

The North Coast Storm Chasers have already predicted the possibility of supercells, bringing large hail stones, flash flooding and thunderstorms as a southerly change moving up the coast is set to see south east winds interact with the higher topography of the north coast to meet with warm northerly winds from Queensland, triggering severe storms.

The Chasers predicted Friday to have "absolutely smashing conditions that will assist with not only thunderstorms but even super-cells (destructive storms)".


Severe weather warning for damaging winds and hail

Destructive supercell could be headed to our region

It's already muggy outside.

At 7.30am the relative humidity in Ballina was at 90%, according to the Bureau of Meteorology, while in Lismore is was at 81%, Byron Bay 89% and Casino 67%.

Temperatures have already reached between 17-21 degrees Celsius in these areas, and are set to rise throughout the day.

The BoM explained that a low pressure trough, which currently lies over northeastern NSW (while the high pressure system is moving over the south and the northwest), will weaken during Saturday as the high moves over the Tasman Sea and strengthens a ridge to northeastern NSW.

The next cold front is expected to cross the state on Sunday and Monday.

The BoM have forecasted partly cloudy conditions for the rest of Friday, with an 80% chance of showers.

A thunderstorm is likely, the BoM said - mirroring the prediction of the NCSC.

Light winds are expected to become southeasterly 15 to 20 km/h in the middle of the day then become light again in the late afternoon.

Daytime maximum temperatures are expected to be in the mid to high 20s.

Saturday Forecast

Partly cloudy with an 80% chance of showers, most likely in the morning and afternoon.

The chance of a thunderstorm.

Light winds and overnight temperatures falling to around 17 with daytime temperatures reaching the mid 20s.

Sunday Forecast

Partly cloudy with a 30% chance of a shower.

Light winds becoming northerly 15 to 25 km/h during the day.

Overnight temperatures falling to around 14 with daytime temperatures reaching around 30.
