Northlanders are being told to brace for heavy rain across a 16-hour timeframe.

MetService has issued a heavy rain watch for the region, spanning 6am tomorrow through to 10pm.

“A front preceded by a strong, moist northerly flow moves east across the country on Friday and Saturday morning, bringing heavy rain and gales to many areas.”

Between 80mm and 100mm of rain was forecast, with peak rates of 20 to 30mm an hour on Friday afternoon and evening.

“Streams and rivers may rise rapidly. Surface flooding, slips, and difficult driving conditions [are] possible,” MetService said.

The national forecaster said the chance of upgrading to a red warning – reserved for the most extreme weather events – was low.

A red warning indicates people need to take immediate action to protect themselves, property and animals from the impact of weather.

MetService encouraged people to clear drains and gutters before the heavy rain.

“Avoid low-lying areas and drive cautiously.”

On Saturday morning, the front pushes off to the east. Behind it, northwesterly winds drag in showers to western areas for the remainder of the weekend. The east of both islands will remain drier.
