SUMMARY FOR THE MONTH OF FEBRUARY, 1917.

With the exception of some places along the northern portion of Cook Strait and a few scattered stations in the South Island, the total rainfall was everywhere above the average, the greatest excess being in the northern and southernmost districts.

The two chief causes of excessive rains were both extra-tropical cyclones. One which ruled during the first few days of the month moved from the north-west down towards the West Coast of the South Island, and passed in the South on the 5th.

The other passed in the Northern districts on the 21st, and was followed by a “secondary” centre, which was effective until the 25th. The latter disturbance was responsible for extremely heavy rain and flooded rivers in the Northern and East Coast districts of the North Island. Some of the northern stations recorded over 5 in. on three consecutive days—viz., 21st, 22nd, and 23rd.

About the 16th a small anticyclone prevailed, and on the 21st and 22nd anticyclonic pressure ruled in and southwards of Cook Strait; otherwise atmospheric pressure was generally below normal, and in consequence dull skies were the rule.
