Storm bringing 'giant hail, destructive winds, heavy rain'
THE Bureau of Meteorology has issued a Severe Thunderstorm Warning for parts of the Northern Rivers for heavy rainfall, damaging, locally destructive winds and large, possibly giant hailstones.
"Severe thunderstorms are likely to produce heavy rainfall that may lead to flash flooding, damaging, locally destructive winds and large, possibly giant hailstones in the warning area over the next several hours," the bureau warned.
The forecast for the wider Northern Rivers is a chance of a thunderstorm, possibly severe and a medium chance of showers along with winds 20-30km/h.
North Coast Storm Chasers said: "Severe thunderstorms south of Grafton are moving NNE and contain large hail (verified by external source)".
Tomorrow there is a high chance of showers and a chance of a thunderstorm predicted.
BoM's weather situation reads: "A weak high pressure system over the northern Tasman Sea extends a ridge to the north coast while a trough over central parts of NSW will continue to move to the northeast of the state."
"This pattern is drawing hot air from central Australia into inland New South Wales, leading to heatwave conditions in some areas.
"The low pressure trough will shift further northeast before stalling and weakening about the northern slopes on Friday and Saturday. Shower and storm activity is expected to be generated by the trough over the next couple of days, though cooler conditions are expected in its wake."
Temperatures reached 37C today in Lismore and tomorrow is also set to bring hot temperatures to the region.
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.

* 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.
