The Bureau of Meteorology issued a severe thunderstorm warning including heavy rainfall, large hailstones and damaging winds for for people in the Northern Rivers, Northern Tablelands and parts of the Mid North Coast and North West Slopes and Plains Forecast Districts just after 11pm last night.

The lightning lit up the sky from behind a thick blanket of storm clouds from about midnight with the region also receiving significant rainfall.

The rainfall will come as a relief for some farmers and agricultural producers in the Valley with a recent heatwave and number of dry days sorely affecting cattle and crops.

For others the storm brings fear of further damaging winds and devastating hailstorms such as the one that hit Carnham Valley and other parts of the Western and North-Western reaches of the Valley last week.
