Weather: Heavy rain, warmer temperatures expected from Tuesday

A wet week is on the way after much of the country finally enjoyed some sunshine this weekend.

Rain will hit the west of the country on Tuesday and could continue through Friday, with heavy rain warnings in place for some areas, according to the MetService.

MetService meteorologist Peter Little said we currently have a high over the country.

“It gives generally stable weather for most places and allows for those generally frigid conditions where there hasn’t been a lot of wind and fairly clear skies overnight,” said

* More hours of sunshine than you think despite record rainfall
* Clear skies before the supermoon
* Severe weather claims affect insurance giant IAG’s results
* Cold start as not a single weather station is above 10C this morning

However, the high would move east allowing a northeasterly wind flow to spread across New Zealand early next week, he said.

“It’s ahead of a low pressure trough over the Tasman Sea,” he said.

“It looks like the rain is going to continue in some places through the end of the week, especially in the center of the country,” Little said.

Heavy rain warnings for the Tasman District west of Motueka, Buller and Westland for most of Tuesday.

MetService also put in place heavy rain watches on Tuesday for the top of the South Island, including the Marlborough Sounds and Richmond Range, Nelson and the Tasman district from east Motueka.

Areas already soaked by rain should prepare for possible surface slides and clear drains of blockages that could cause flooding, Little said.

“There’s definitely more choppy weather along the way, which isn’t ideal given that a lot of the places where the rain is expected to fall are places that have already had a lot of rain this winter and haven’t really had the chance to dry out.”

Temperatures are also expected to rise after no weather station rose above 10C on Saturday morning.

Frosts reached Auckland and Northland on Friday and Saturday morning.

Particularly cold temperatures hit the South Island on Saturday with Timaru at -2C, Queenstown at -3C and Blenheim at -3C.

MetService forecast a wet week for Auckland, with rain expected to intensify from Wednesday. Temperatures will warm up, with highs of 18-19C expected later in the week.

Wellington is also likely to see rainfall in the second half of the week, with strong northerly winds expected. Low temperatures are expected to be around 12°C and high temperatures of around 15-17°C are expected.

Temperatures will rise in Christchurch this week after a cold weekend, according to MetService.

Lows will be around 7-9C and highs could reach 20C by the end of the week. Rain is expected to hit the city on Tuesday and continue through Thursday, but should ease by next weekend.
