Mount Isa has registered an astounding 318.6 millimetres of rain this February, setting a new all-time record for the month and significantly outpacing previous highs.
A Month of Persistent Rain
Rainfall was a frequent occurrence throughout the month, with measurable precipitation on 17 out of 24 recorded days. The town also experienced a notable period of 12 consecutive days of rain, contributing to the overall high total.
Among these events, one particular night saw more than 40mm of rain fall, adding to the intense conditions. A senior meteorologist from the Bureau of Meteorology has officially confirmed that this truly is the wettest February on record for Mount Isa.
The heavy and consistent rainfall is primarily attributed to a low-pressure system that has been situated over the south-eastern parts of the Northern Territory. Further storms are forecast for the region, indicating the wet conditions may continue.
Significant Local Impacts
The increased water levels have led to periodical closures of crossings in Mount Isa, particularly those affected by the Leichhardt River. Mount Isa City Mayor Peta MacRae acknowledged the rainfall as a significant event, highlighting that the region had largely avoided widespread rain and flooding earlier in the season. "This rainfall is a significant event for Mount Isa," Mayor MacRae commented.
Crucially, both Lake Moondarra and Lake Julius, which are vital for supplying water to the town, have reached 100 percent capacity. This addresses long-standing concerns about water availability and secures the town's water supply for the year ahead.
