Southern Papua New Guinea is currently experiencing the La Nina weather pattern and will be experiencing more rainfall in the coming months.
National Weather Service Acting Director Jimmy Gomoga told PNGFM News, the provinces that will be affected include Western, Gulf, Central, NCD, Milne Bay and Northern Provinces.
Gomoga said La Nina is an extreme phase of a naturally occurring climate cycle when the ocean surface temperatures is cooler than normal in the Eastern and Central Pacific Ocean creating low-pressure zones that contribute to increased rainfall.
He added that the affected region will also be experiencing severe thunderstorms and lightning.
Meanwhile he also warned people of the dangers associated with the rainy season including flooding and slippery road conditions as well as falling trees and power poles.
