A remarkable rainfall event in Scone, NSW, has sparked hope and discussion among farmers and meteorologists alike. In just two hours, Scone shattered its annual rainfall record, with an astonishing 102.6mm recorded at the airport gauge. However, this intense storm, while welcome, has left many questioning its impact on the region's ongoing drought.
A Record-Breaking Downpour
The Bureau of Meteorology's (BOM) data revealed that the Yarrandi Bridge gauge recorded an impressive 108.4mm in the same 24-hour period, with some private gauges indicating even higher totals, nearing 150mm. Senior Meteorologist Ilana Cherny confirmed that most of this rainfall occurred within a mere two-hour window, setting a new annual record for the Scone airport station, which has been collecting data for over three decades.
Patchy Relief
But here's where it gets controversial: the storm's impact was highly localized. While Scone airport received a deluge, less than 5km away in the town itself, rainfall was significantly lower, ranging from 15-25mm in the same four-hour period. Villages nearby, such as Parkville and Aberdeen, recorded less than 10mm, highlighting the patchy nature of the storm's coverage.
The BOM also observed extreme weather conditions, with wind gusts reaching 96km/h at the Scone airport site.
A Single Storm's Limitations
Farmer and agronomist Ross Watson, whose property seemed to be at the storm's epicenter, emphasized that despite the record-breaking rainfall, it would not immediately alleviate the dry conditions. He explained that while his property received close to 150mm, many others in the region received far less, emphasizing the variability of the storm's coverage.
The Hunter region has been experiencing a prolonged period of dry weather, impacting pasture growth and livestock numbers. While the conditions are not as severe as those faced by farmers in the southern and western parts of NSW, who have been relying on trucked-in feed and water for months, the region's farmers are still feeling the strain.
In August last year, parts of Scone were under flood evacuation orders, but since then, the rain has been scarce, with Mr. Watson describing it as if "the taps had turned off."
His Saturday night rainfall was equivalent to the total rain recorded since spring, highlighting the significance of this event. However, he cautioned that a single storm would not be enough to turn the season around.
"Many might think I'm lucky, out of drought now, but they might not realize that their smaller, more effective rainfall has provided a deeper moisture reserve for their plants."
Mr. Watson explained that the intensity of the rain meant much of it ran off, especially with bare paddocks in the district, leading to potential soil erosion. He emphasized the need for gentle, soaking rain over multiple days to truly make a difference.
"We need another 75-100mm before winter to turn this around."
And this is the part most people miss: it's not just about the total rainfall, but also about the timing and intensity. Effective rainfall is key to ensuring the water reaches the root zone, where plants can access it.
So, while this storm has brought much-needed relief, it's a reminder that weather events can be highly variable and that a single storm, no matter how intense, may not be enough to break a drought.
What are your thoughts on the impact of weather events on agriculture? Do you think this storm will be a turning point for the region's farmers, or is more needed to truly recover from the drought? We'd love to hear your insights in the comments below!
