Post by: Rwood on February 15, 2012, 06:41:49 AM
June 1977:   During June pressures were near normal over New Zealand but higher to the north and south of the country. There was a greater frequency of easterly winds, and two spells of cold southerlies from the 3rd-9th and 20th-22nd. Conditions were cloudier and wetter than average over the major part of the country with the exception of some areas in Central Otago and Southland. On the 28th, winds gusting to probably more than 100 knots caused major damage to ski huts on Mt Ruapehu.

Rainfall: Rainfall was above normal over most of the country, the only areas below normal being parts of Westland, most of Otago, and Southland. Many areas in both islands were above normal by more than 50%, and in Poverty Bay, Hawkes Bay and parts of central Canterbury more than 150% above. Some areas of Central Otago and Southland recorded less than 50% of their normal. A severe thunderstorm early on the 4th brought heavy rain to the Wellington area. Almost 47mmm fell at Kelburn in less than 4½ hours. On the 20th-21st, heavy rain around Gisborne caused widespread flooding and slips and many homes were evacuated. A fall of 156mm was recorded in Gisborne in 24 hours, the highest for June since 1894 and the highest in any month since 1910. 218mm fell from 9am on the 20th to 9am on the 22nd. During this period heavy falls were also recorded in Auckland, Waikato and Bay of Plenty, with many places affected by flooding and slips. On the 26th-28th, gales and heavy rain in both islands caused flooding and damage in many areas. During this time heavy falls of snow were reported in the South Canterbury back country, with rivers running high and widespread flooding. On the 29th large hailstones at Pahiatua damaged crops and property.
