At the moment there are quite a lot of rain echoes showing up on our radar network. However, when looking at the observations there is currently no rainfall reaching any or our raingauges. (however, not for long)

How's our rapidly deepening low doing?

This loop shows infra red satellite images, where high cloud appears as red. South of the jet stream (the smooth line of cloud) and east of southern Tasmania is the start of our incipient low. As the loop progresses this blob of cloud rapidly increases in size. By the end of the loop it lies just west of the bottom of Fiordland, and a circulation is...

Where's the bomb at?

The 'bomb low', which means a rapidly deepening low pressure centre, is currently in a juvenile phase out in the Tasman. It sits under the polar exit of a jet stream, which enables the rapid deepening. This, combined with a strong boundary between warm and cold air, give it the energy required to start to rotate and deepen into a bomb low.

Although the low centre is...

HEADS UP - 'Bomb' Low

If a low which undergoes explosive cyclogenesis, meaning it deepens very rapidly is a short time, exceeding a certain amount in 24 hours it can be defined as a 'bomb' low.

There is a low approaching New Zealand on Wednesday which meets this criteria and it is expected to bring damaging winds to exposed parts of the South Island and lower North Island, and extremely...

50th Walsh Memorial Flying School, Matamata

16km from Hobbiton, 40km from Hamilton and a very long way from our offices in Wellington. Built by American troops in the second world war, this grass-strip runway sees little action these days, except for occasional gliding events and model aircraft meets. That is apart for two weeks in January every year, when it suddenly becomes the busiest...
