Heavy rain is currently falling over the north of the South Island, and rain is expected to spread to most North Island places on Saturday.

“The trough bringing wet weather to these places over the next day or two is quite complex, and MetService’s Severe Weather Forecasters are keeping a close eye on it,” commented MetService Weather Ambassador Bob McDavitt.

“For northern and central New Zealand on Saturday, there is reasonable uncertainty over the timing and location of possible heavy rainfall.  Some places are likely to see short periods of high-intensity rainfall, others could see big 24-hour rainfall totals from steady falls, and yet others are likely to have very little rain.  It will be important to keep checking MetService’s Severe Weather Warnings and Watches as the day progresses, through the MetService website or the news media.”

McDavitt added that high rainfall intensity can cause surface flooding even if the total rainfall doesn’t amount to a huge number.  “And the rain may fall in several episodes rather than in one long period.  Now is a good time to clear the gutters of autumn leaves in preparation for this onslaught of rain.”
