Weather: Warning as West Coast faces more heavy rain, gales

Heavy rain and havoc is back on the way for the beleaguered West Coast.

An active front brings a burst of heavy rain this Sunday night and Monday morning as a Tasman Sea low connects with the remains of ex-Cyclone Trevor.

"This front brings a period of rain or showers to most places, which will be heavy for a time in western areas," MetService warns on Facebook.

"A severe weather warning has been issued for a period of heavy rain in Westland, which was badly affected by flooding last week. A heavy rain watch is in place for the remainder of the West Coast and Nelson."

The rain will strike a region still struggling to recover from the last deluge. The West Coast town of Haast is still without power, days after the region was pummelled by record rainfall.

Weather Watch says that following the recent deluge slips will be more likely and rivers may rise faster.

Gale force winds are also expected to strike some regions.

"Following the passage of the front, a period of westerly gales is forecast in the far south," MetService warns.

"There is moderate confidence of northerly winds reaching severe gale strength in exposed parts of Fiordland, Westland, northern parts of Southland, inland Otago, and southern Canterbury High Country."
