Meteorological Observations




On the 20th another spell of westerly weather commenced. Pressures were very low in the South from the 21st to the
23rd. Strong westerly winds prevailed, and on the 23rd gale force was reached in many places from Nelson and Marlborough
northward. By the 24th the last of the deep westerly depressions had passed. Barometers rose, and strong south-westerly
winds to gales prevailed until the 26th, when they began to decrease as an anticyclone approached from the west. The
centre of the latter crossed the Dominion on the 29th, and on the 30th pressure was again falling. There was much snow
on the ranges from the 22nd to the 25th, and numerous hail and thunderstorms occurred. Some flooding was experienced
in Otago. On the 23rd a number of small tornadoes were reported from the western side of the North Island, each doing
considerable damage over a short and narrow path.
