Significant tropical-rain event 22-25 Jan

[iomkiwi]

Can someone tell me if it is raining up in the North Island? Radar is inconclusive....

Not at Present!

[iomkiwi]

Its the warm front thats the heavy rainfall producer and I reckon once thats through the event is over.

Looks like that is pretty much what has happened up here.

Issued at: 8:26am Sunday 23 January 2011

A trough of low pressure lies over the North Island. A low of subtropical origin lying north of New Zealand at 8am is moving southwards and should move onto Northland this evening. A broad sheet of rain associated with both these systems covers the North Island, with heavy rain expected in many northern and central areas. See latest Severe Weather Warning and Watch for more detail.

Maybe that's why the new warnings have come out?

Heavy rain back on at Kaukapakapa

[Manukau heads obs]

M/S have caught up with the fact the rain has eased in the north now

Heavy rain is easing about Northland, Auckland and Coromandel Peninsula this morning, but further significant heavy rain is likely today and early Monday in regions from Waikato down to Whanganui and the central North Island high country, and across the Bay of Plenty to Gisborne and Hawkes Bay.

just had another5-10mm of rain added in 10 minutes!

[NZstorm]

Met Service should have had a better handle on the situation this morning as it was obvious the warm front was about to clear the north.

Yeah, the rain had pretty much cleared Northland before they put the warnings out. I doubt we'll even see another 20mm here

[NZstorm]

Now that we are into the warm sector the rainfall options are drizzle or convective showers. Not too sure about the convection but brief heavy showers still possible I guess, more particularly if there is any heating.

[Philip Duncan]

Reports coming in to WW of the sun coming out in Northland NZStorm - that could help with convection

amazing to walk outside...19C inside with a low DP, 22C outside with 100% humidity !

[bmo]

Sun is coming out here in Kaukapakapa the winds have increased in speed rapidly and have begun to kill a few branches of the trees!

19? what a cold house No condensation on windows here with the temperature change, maybe because it was warmer inside all along...

[tgsnoopy]

No condensation on the house windows here, 22.8 in 21.2 out at present. But I note glass in structures outside do have some condensation on them. Rain has now eased and the wind is picking up.

[Avalanche]

Why has the metservice not got rain warnings out for the wellington region yet? latest sate images show that cloud coming right over the top of us here and its been raining most of the morning now have 10mm so far to me its just getting started with alot of cloud still heading our way.

[bmo]

The centre is right on top of me!!

[Michael]

Gday Avalanche - I see MS are keeping a watch open for the Wairarapa (not sure about WLG), we have had 11.6mm today (since 9am) and 16mm overnight. Others will know more detail, but I don't think that the rainfall rates and amounts meet warning criteria and/or are sufficient to issue a warning at this stage for the Lower NI. Upper NI areas have been receiving in excess of 20mm per hour......

[Avalanche]

thanks shepards valley you could be right still seeing some heavy rain bands heading your an my way its the prolonged rain im more thinking of tho . The low is very slowly moving south which means it could stick around for a while longer than i thought.

[NZstorm]

Some nice rainfall tallys in the BOP, Kawerau showing 222mm, Rotorua 161mm. And I see Hamilton got 110mm.

[Avalanche]

Wow thats some big totals there still raining too. Still raining here Wellington 13mm now

[Michael]

According to Island bay weather been no rain since 9am,cold their max so far only 12.9c.
