Weeks after it was hit by a severe storm, Northland is in for another big deluge

But, forecasters say the system predicted to soak the region on Tuesday will prove more of a short, sharp hit.

MetService meteorologist Stephen Glassey says a low pressure system, currently located in the northern Tasman Sea off the coast of Australia, is expected to move eastward and on to the upper North Island.

He says exposed parts of Northland could receive between 70mm and 100mm over a period of hours on Tuesday morning.
