A former New Zealand climate scientist working in California compares tropical cyclone Sandy to the Wahine storm.
Sandy made landfall on the east coast of the United States about 8pm local time on Monday.
Jim Salinger, who is based at Stanford University, told Morning Report that an active cold front from the north will combine with the hurricane, causing a weatherbomb south of New York City.
He said the Wahine storm that struck Wellington in 1968 killing 51 people started in a similar way, when an active cold front from the Tasman sea combined with tropical cyclone Giselle over Wellington.
The Wahine storm affected most of New Zealand, causing high winds, flooding and landslides.
