yes, big flooding here in our valley now
77mm or so here so far

Wind is quickly ramping up here now

Looks like great barrier could be in the firing line for a decent thunderstorm.

Meanwhile very gusty and very from the south. Don't often get heavy gusty rain from the south.

SW wind change has now made it to Gt Barrier

Starting to get a bit cool now, temp dropping a bit now down to 12.7°C and still dropping....

Flash flood here with 10mm in 30 mins all as runoff. Water in places I've never seen.

34mm for this event here. I see the Coromandel's Pinnacles recorded 119 mm for May 11-12, similar to the 123mm recorded at MS's Farewell Spit site on May 10-11 (compared to 62mm at Nelson Aero).

Probably not quite as severe as some of the storms we've had in recent months, but it looks like most North Island places received around 40mm or more over the last 2 days.
