Perth set for downpour as ex-tropical Cyclone heads south
Perth could see five times its monthly average rainfall in one day when the remnants of ex-tropical Cyclone Joyce arrive in the metro area after tracking south from the Kimberley.
The cyclone was downgraded to a tropical low on Saturday, but the Bureau of Meteorology warned the system was still bringing damaging winds and the risk of flooding.
BOM duty forecaster Pete Clegg said Perth residents could be in for a surprise.
“Five to 10 millimetres would be the average amount of rainfall that we’d get out of a cold front in Perth.
“You’re talking of getting 30 to 50 millimetres — obviously a fair bit more than that — and definitely not what you’d [ordinarily] get in summer, like you’re seeing today, a nice sunny clear day,” Mr Clegg said. The popular Karijini National Park near Tom Price has remained closed after rangers moved people out of the campsites and Karijini Eco Retreat on Friday.
Deluge could reach south of Perth
Perth could see heavy rain from late Sunday through to tommorow morning.
“It’s still a little bit uncertain exactly how much we’ll get, because as far as the track of the low as it comes down through the South West Land Division it may push offshore, in which case those heavier falls could remain to the north-west of us,” Mr Clegg said.
“But certainly it looks likely that we’ll see at least more rainfall than you’d expect for an average January day.
