Kim Westcott from Weatherzone said over the next several hours storm conditions are expected to intensify.

“There is currently a severe weather warning for the Mid North Coast of NSW which includes all of the Port Macquarie-Hastings region,” Ms Westcott said.

“With the severe warning thunderstorms are likely to produce large hailstones and damaging winds right across the region and people are advised to stay indoors.

“The weather warning is a result of a low pressure system which is building and will stay around for the next few days.”

The warning includes Port Macquarie, the Camden Haven, Wauchope, Taree, Armidale, Sawtell, Coffs Harbour and Dorrigo.

Ms Westcott said this weather activity was fairly typical for this time of the year.

“As we look to the seven day forecast we can expect to see more storm conditions coming on Friday with wind from the west and rain from the south,” she said.

“On and off showers are likely for the rest of the week and then these storm conditions should ease over the weekend but will resurface again early to mid next week.

“That said people can possibly expect rain over the weekend as well.”

The NSW State Emergency Service (SES) have also advised people to move cars under cover or away from trees and secure or put away loose items around the house, yard and balcony. 

They also said people should keep at least eight metres away from fallen power lines or objects that may be energised, such as fences if they come across them.

Report fallen power lines to Essential Energy on 132 080 and for emergency help in a flood or storm contact the SES on 132 500.
