Weather in Perth: Bureau of Meteorology warns of huge rainfalls as Cyclones Odette and Seroja rage

0


Residents of Perth are urged to prepare for heavy rains as a rare weather event unfolds in the state’s north.

Huge falls are expected across the state following a tropical cyclone and a second tropical depression developing off the coast.

The Bureau of Meteorology has warned people between Onslow and Perth who should be on alert for heavy rain that could lead to flash floods and dangerous surf conditions.

While Perth is unlikely to be directly affected by the cyclone, it is expected to be marked by rainfall from this weekend.

Up to 15mm of rain is expected on Sunday, while a whopping 30mm could follow on Monday – which would be the wettest day since August.

While Perth recorded just 13mm of rain for the entire month of last April, the next wet spell could see that amount hit in just one day.

But WA’s Midwest and Gascoyne areas are expected to face the worst weather conditions, with the Bureau warning of heavy winds and rain.

The first hit is expected at Exmouth on Saturday evening, with a brief but possibly intense period of heavy rains and strong gusty winds – the result of a tropical low which is expected to intensify up to the category one named Cyclone Odette late today or early tomorrow.

Meanwhile, a second cyclone already named Cyclone Seroja is expected to cross the coast at category two or three intensity on Sunday evening or early Monday between Carnarvon and Jurien Bay.

The Bureau of Meteorology has warned that destructive winds with gusts of around 150 km / h and intense precipitation that could lead to flash floods are expected near the system as it moves along the coast.

Heavy rains and damaging winds are expected to continue inland across the wheat belt on Monday.

The speed at which Cyclone Seroja is expected to move means the worst conditions are expected to last for three to six hours.

Cyclones that form in April in the western region are generally more likely to move south outside the tropics, according to the BoM.
