Thunderstorms hit parts of NSW as bushfires rage

Rain not expected to extinguish all 70 fires raging across the state, and firefighters fear lightning could spark further blazes

The state's fire danger ratings were expected to improve somewhat on Sunday as showers offered firefighters some reprieve.
