People in the path of severe storms and flood threats will receive clearer, localised warnings as the NSW SES adopts a new alert system.
The change comes as NSW approaches a storm season threatening to be wetter than usual, Emergency Services Minister Steph Cooke says.
"The annual increased frequency of storms, strong winds and rain will coincide with a third consecutive La Nina, which means communities right across the state will remain on high alert," she told reporters on Thursday.
