Tasmania drying out after very wet October, wettest since 1947 in Hobart

Brett Dutschke

Tasmania is now drying out after a low-pressure system delivered flooding rain in the past week which contributed to much of the state having one of its wettest Octobers on record.

Hobart ended up having its wettest October in 74 years, receiving 160mm for the month, 99mm more than average. This was also city's third wettest October in 140 years of records.

Almost all locations in the state recorded more than their average monthly rainfall. Some of the most extreme rainfall occurred in the northeast where many places gained 200-to-500mm, two-to-four times their monthly average.

Mt Barrow amassed 509mm for the month, 370mm more than average, and one of the wettest spots in the state.

It ended up being the wettest October in 95 years of records at Bicheno (203mm, 147mm more than average), 68 years of records at Orford (230mm, 172mm more than average) and in 63 years for several centres, including Pioneer (239mm) and Lake Leake (198mm).

Westerly winds have delivered a few showers to the state's west on Sunday, while the east has become dry, allowing flooding to ease. High pressure will clear showers from the west early this week and keep the rest of the state dry.

However, just as in October, the dry spell will only be short-lived, rain likely to redevelop on Wednesday. But unlike October, this rain looks rather brief, clearing up on Thursday. This brief wet-then-dry pattern can be expected for the next week or so as front after front cross the Southern Ocean. These fronts will bring most of their rain to the west, leaving much of the east to pick up typically modest and brief rainfall.
