Afternoon heating and convergence zones are creating large cloud build ups across parts of the upper North Island reports WeatherWatch.co.nz.

Readers are reporting large clouds over Thames, Auckland and in the Bay of Islands.

Manuela Hornell told us via our Facebook page that “heavy, heavy rain drops” were falling in Opua, Bay of Islands, while Andy Harwood reported “good looking” cloud build ups north west of Thames.

In Auckland a large line of black clouds has formed out west and is slowly drifting towards the CBD and North Shore.  WeatherWatch.co.nz forecasters say there is a moderate chance of another funnel cloud forming this afternoon but points out it is rare to have them two days in a row.

We also predict the chance of a heavy, localised, afternoon heat shower.

We’re keen to hear from people who have seen large cloud build ups, or experienced heavy drops of rain today – post a comment below or sign up to our Facebook page.
