Many thanks DT-NZ for your efforts with the photos.

I am no expert on diagnosing tornado strength from damage but earlier comments about F0 to maybe F1 seem to be about right??

Looks like today's event has passed by with no grief (or none that we've heard about yet). The whole thing was not nearly as active as yesterday's event. We've had about 600 lightning strikes last 12 hours whereas there were several thousand yesterday. Also the indiviual cells strengths on the radar were less today.

Cheers,

Paul

saw a flash outside (im in auckland) from the corner of my eye a few minutes ago. not sure if it was lightning or not.

Some lightning strikes near our West Coast over the past hour from shower activity that is moving onto Auckland now.

Paul Mallinson · Unread post by **Paul Mallinson** » Sun 05/07/2009 21:57

Yes it was. There is a narrow but rather intense line of showers wnw to ese extending onshore into the Auckland area - part of a hook on the bottom end of the frontal band that moved across Northland this evening. Looks like some small hail in it too.

that cell has intensified and is now looking fairly good. hopefully it doesnt go to far SW, as id enjoy a nighttime thunderstorm tonight!

jamie · Unread post by **jamie** » Sun 05/07/2009 23:04

i would enjoy a good night time thunderstorm too, considering i missed the last one $\:D/$ .. not sure if i can possibly stay up any longer though. I havnt had any sleep in 40 hours and only 4 hours in the last 63 hours

Those Photos of Kaitaia hospital show a weather station on the roof!, anyone know who's it is and if there is data recorded from it? would be very interesting to see that

David · Unread post by **David** » Mon 06/07/2009 08:19

That rain area gave 12mm here after 11pm last night, heavy at times, with 6mm in an hour. Ground is very wet now.

The AWS on the roof of Kaitaia Hospital is a MetService one. The maximun recorded wind gust from that AWS was 47 knots between midday and 1pm on Saturday.

surprised it was not more, but it might have only got the edge of it

Pleasant morning here so far, light winds, sunny 15C. Cb tops off to the W/SW.

I wonder if those readings aren't taken roughly on the hour, rather than the peak gust during that hour?

Niwa's Kaitaia Ews site, which is just less than 2km S of Kaitaia Hospital, shows NW gusts increased to 22 knots at 12pm, 23 knots at 1pm and then 42 knots at 2pm, before dropping back down again. Similarly, Kaitaia Aero, which about 6km N of Kaitaia Hospital, shows gusts to 22 knots at 12pm, 26 knots at 1pm, but only 30 knots at 2pm.

Just got a good wee shower here after what started off as a pleasant morn.

The peak wind gust from the Kaitaia Hospital AWS is the maximum wind gust recorded throughout the whole hour.

Hmm... interesting! Thanks. Would have to go with Brian's comment then.

Is that a stevenson screen there too on top of Kaitaia hospital? (I'd be thinking it'd be giving less than desirable observations...)
