Conditions are ripe for thunderstorms to pop up during the afternoon in the middle of the North Island for the next few days.

“The right combination of ingredients is coming together”, commented MetService Weather Ambassador, Bob McDavitt. ” A moist easterly flow is likely to prevail over the North Island this week, and this is expected to combine with daytime heating of the ground and cooler than normal air aloft to trigger the sporadic outburst of intense afternoon showers over the inland high ground until Thursday.”

Mr. McDavitt added that, once brewed, these intense showers are likely to drift around and spread off the hills and across the plains in Hawke’s Bay and Bay of Plenty. “They will drift at the whim of converging sea breezes. If you hear thunder, seek shelter for the next hour or so, and be aware that runoff from nearby showers can briefly bring surface flooding.”

A MetService Severe Thunderstorm watch is now in force for central North Island for Monday afternoon and evening and more may be issued over the next few days.  These afternoon thunderstorms are likely to reach a peak in intensity on Tuesday, but further intense showers are possible on Wednesday and Thursday.  People in the area should check the latest MetService updates and plan accordingly.
