ExtremeJanuary 1980 South Island Weather Bomb ( 1980-01-16 )

100 years

South Island

Multi HazardMulti Hazard at South Island
Duration:   3  days - From the 16th till the 18th of January.
Comments:

CauseAn unusually deep depression developed just east of Otago. The deepening rate of the low was 1.6 bergeron, putting it well within the definition of a “bomb”. Northwesterlies brought moist, tropical air onto New Zealand and the subsequent strong baroclinicity, along with increasing shear vorticity, were major contributors to the development of the low. The strong upward motion field and the strong onshore southerly winds that resulted led to a different distribution of rainfall than in the 1978 event.

Stock DamageStock losses were estimated at 15,000-17,000 by the Ministry of Agriculture and Fisheries.

Heavy RainHeavy Rain
Comments:

CommentFlood-producing rains occurred within a 24-hour period from 2pm on the 16th to 2pm on the 17th.

CommentThe rain was largely distributed in resonse to orographic stimulation. The heaviest rains occurred in the Catlins Ranges of the Otago-Southland border as well as in the Pomahaka, Waikaka and Waikaia catchments. The rainfalls in the Pomahaka, Waikaia and Waikaka catchments were higher than in the 1978 event by about 25 mm. This also affected the headwaters of the Taieri River more than in 1978.

CommentThe area where the maximum 24-hour falls exceeded a 50 year return period for this event was slightly smaller than and displaced a little towards the southwest of the 1978, 1980 and 1984 events.

FloodingFlooding
Comments:

CommentParts of Otago and Southland experienced extremely severe flooding for the second time in 15 months (similar event in October 1878).

CommentFlooding was caused by the rain persisting with a moderate to heavy intensity over a period of some 20 hours at each site. The Clutha and Mataura Rivers received heavy rain only in the lower parts of their catchments but their tributaries the Waikaia, Waikaka and Pomohaka experienced floods similar to those in 1978.

Total DamageDamage from the floods was $11.00 million (2004) ($12,669,100 2008 dollars).

Insurance PaymentInsurance industry payouts totalled $2,300,000 ($10,066,200 2008 dollars).
