Tropical Atmospheric River 13-17 Dec

Unread post by Razor »

Thought the upcoming week warrants a new thread. Significant flooding potential for large parts of NZ as the AK Covid bubble bursts. Going to be an interesting week

This December is already looking different to 2017 when sea temperatures were also very warm, December 2017 was a dry month for NZ.

MS as at Sunday morning:
Severe Weather Outlook
On Monday and Tuesday, a low pressure system is expected to move onto New Zealand from the Tasman Sea. The low should move slowly southeastwards over the country and deepen on Wednesday and Thursday, bringing significant rain and strong winds to many areas.

There is low confidence of heavy rain in the west of the North Island from Northland to Taranaki, including Coromandel Peninsula during Monday. During Tuesday and Wednesday, there is moderate confidence of warning amounts of rain for the north and west of the North Island from Northland to the ranges of Gisborne, and to Wellington, also northern Marlborough and Tasman. There is low confidence of rainfall accumulation meeting warning amounts in southern Marlborough, eastern Canterbury during Wednesday and early Thursday, as indicated on the chart.

In addition, there is low risk of severe northeasterly gales in exposed parts of Northland, Auckland and Coromandel Peninsula during Wednesday, and severe north to northeasterly gales in exposed parts of Gisborne during Wednesday and early Thursday.

Latest GFS seems to want to cross a low over the upper south Island mid week. Parts of our hood are still getting over the winter atmospheric river event... don't need another one!

The next one we can probably handle, its the three or four coming after that which will be the problem...

Heading down to Central Otago and Fiordland for a couple of weeks mid to late January. La Nina years are famous for brilliant weather down there. Hope I haven't just jinxed it

I think they only do that for US named TC's.

The BoM, Fiji Met and JMA usually carry on alphabetically from the last season, i.e. the BoM's last named TC was Odette off WA in April this year.

Around 17mm of warm rain here late yesterday, lawns and gardens are looking great. The Jakaranda trees are putting on a purple show around Mt Eden currently.
