The short-lived storm cell hit the Central Australian town shortly after 3:30pm on Monday, with the Bureau of Meteorology (BOM) recording a wind gust of 96km/h at 3:44pm. The BOM said a surface trough coinciding with a warm and unstable air mass in southern parts of the Northern Territory had resulted in severe thunderstorms.
Trees were pushed onto roads, powerlines and roofs by the intense winds. The Alice Springs Hilton DoubleTree was among the properties that suffered significant damage, with its ceiling damaged, images show.
Power and Water Corporation said in a statement on Monday afternoon that about 9,000 properties had lost power due to damage caused by the sudden storm cell. Crews were assessing the damage and working to restore services as quickly and safely as possible. The communities of Arumbera, Burt Plain, Ilparpa, Simpson, Hermannsburg, Hugh, Namatjira and Wallace Rockhole were also affected. The corporation reminded people to stay away from fallen trees and powerlines and to always assume powerlines are live.
NT Emergency Services (NTES) reported receiving 33 calls for assistance by 5pm. NTES's Adam White told reporters that there were reports of multiple trees down and damage from hail and winds, describing the storm as very short-lived but intense. He urged residents to remain vigilant in the coming days and to check SecureNT for updates.
This was the second storm to hit Alice Springs in less than a week. The BOM said two storm cells were moving east over parts of the Simpson and Lasseter deserts and were likely to persist through the early evening.
