A severe storm brought torrential rain to parts of Western Australia today. Moist and unstable air, feeding into a trough, triggered scattered storms throughout eastern and interior parts of Western Australia. Warburton was drenched with up to 5mm in 10 minutes after lunchtime. A total of 67mm was recorded in about 4 hours, which is almost twice their monthly average. Warburton could possibly break its 1946 record of 78mm in 24 hours if storms continue this afternoon.
