Are more tropical cyclones coming?

Keep the brollies handy there is a chance a tropical cyclone is heading our way.

WeatherWatch.co.nz head forecaster Philip Duncan says storms are brewing north of country and there's a chance they could be edging towards New Zealand in the coming weeks.

He says they will have more of an update on Thursday.

At the moment tropical cyclones are likely to form around the Solomon Sea, Coral Sea and also the Pacific between northern New Zealand and Fiji.

There is some threat to New Zealand even if confidence levels are currently low at around 25 per cent, Duncan said.

The biggest of the storms looked to be the one furthest from New Zealand, up around the Solomon Sea.

Duncan said data WeatherWatch.co.nz trusted from various global computer models suggested this cyclone has "severe" potential being in such ideal conditions.

"The lows that may form closer to New Zealand look significantly weaker but still have the potential for some severe weather, but perhaps more importantly may bring some rain to dry areas," Duncan said.

He said despite the three previous cyclone threats in the New Zealand area so far this year, all have been stopped due to high pressure before reaching the country.

"High pressure looks to dominate in our area still, maybe for the rest of March, but there are some cracks showing in this solid belt of pressure and is why we've seen some soaking rains in recent days - so anything is possible," Duncan said.

WeatherWatch.co.nz reports have stressed March was the peak of the South Pacific cyclone season so it was very normal to see tropical storms north of the country at this time.
