A “one in 20 to 50-year” rainfall event has battered Broome, with destructive winds and a deluge of rain soaking the famous tourist town and leaving parts underwater. Incredible footage has emerged of locals taking in the wet season event on Sunday, with 179.4mm of rain falling on the Kimberley town by 8.30pm. Photographs taken in Chinatown show a yellow Suzuki Swift being trapped in the flooding, while one child kayaked past the swings and slide at a playground. Mangrove Cricket Club posted a video of two men throwing their fishing lines, beers in hand, into red running waters in the street, captioning the video “fishing competition happening in town”. There have also been unconfirmed reports the town was hit by a tornado. A severe weather warning has been issued, with Broome, Derby, Bidyadanga, Cape Leveque, Cockatoo Island, Fitzroy Crossing, Kalumburu, Kuri Bay, Lombadina, Mitchell Plateau, Troughton Island and Mount Barnett under alert. “People in the north of WA may experience this type of weather each year at this time but heavy rain may cause damage to property and make road conditions hazardous,” the Department of Fire and Emergency Services said. “Take care in areas that have been flooded and be careful driving on gravel roads as surfaces will be slippery and muddy, and vehicles could become bogged.” The Bureau of Meteorology has warned of an active monsoon trough, which extends across the Kimberley. “A developing tropical low near the WA/NT border will move into the southeast Kimberley today and become slow-moving across the southern Kimberley or adjacent North Interior on Monday,” the authority said. Bureau of Meteorology duty forecaster Angeline Prasad said it was a “one in 20 to 50-year” rainfall event for the region. Ms Prasad said Broome received 66mm of rain in 30 minutes, and then 80mm in one hour in the early afternoon, which she said was a large amount of rainfall in a small amount of time and caused the flash flooding. “So a bulk of the 140mm fell within the hour, so around 1pm we did see those intense falls over Broome,” she said. The State Emergency Service has responded to seven calls for help, mostly for water ingress and flooding. Some roof damage has also been reported.
