He said although Taranaki had a lot of rain overnight and this morning, the forecast was looking better.
Ferris said about 300 lightning strikes hit the central North Island this afternoon.

Sewage overflows have been reported at pump stations in New Plymouth and public health warning signs are going up at beaches after the rain.
The district council has closed Calvert Road in Moturoa, Brougham Street in the city and Egmont Road between Katere Road and Henwood roads due to flooding.
It has also closed the Huatoki Plaza and Puke Ariki underpass due to rising water levels.
Mayor of New Plymouth Neil Holdom warned residents to steer clear of contaminated beaches, rivers and streams.
Holdom said the city's emergency response team had been mobilised and public health warning signs had gone up at contaminated areas.
The city's wastewater treatment plant was working at full capacity but coping well, he said.
A flight from Wellington to Hamilton was diverted to Auckland today after a suspected lighting strike.
An Air New Zealand spokesperson said the aircraft was being assessed by engineers in Auckland.
Passengers were put onto another flight from Auckland to Hamilton.
The airline said lightning strikes were not uncommon and pilots were trained for the scenario.
The council has mobilised its emergency response team and has crews on the ground clearing drains and removing debris.
The Transport Agency says a slip is being cleared from State Highway 3 at Tangahoe south of Hawera.
One lane is flooded at the intersection of SH3 and Dudley Road south of Inglewood and a 30km/h speed limit is in place.
Flooding is also causing distruption in Egmont Village and further south on SH3 at Kākaramea.
On State Highway 45, flooding was reported at multiple locations between Ōkato and Opunake.

MetService says rainfall this heavy can cause surface flooding and flash flooding, especially about low-lying areas such as streams, rivers or narrow valleys, and may also lead to slips.
The upper South Island are not likely to escape the wet weather, with the Kaikōura Coast and Takaka Hill and Arthur Range areas under a heavy rain watch.
