Tropical Cyclone Map Sat April 10 pm

Tropical Cyclone Seroja is beginning to take a more south southeasterly track as it curves around towards the coast

 Seroja is expected to intensify overnight, possibly reaching Severe Category 3 as it starts its southeastwards track towards the coast. During Sunday the system will accelerate towards the coast, and should weaken back to Category 2 before it crosses the coast.

 The cyclone should gradually weaken as it moves inland on Monday but is still likely to be causing gusty winds east and north of the track, and heavy rain close to the track, as it crosses over the south of the state.


Gales with gusts to 100 kilometres per hour are likely to develop in an area between Cape Cuvier and Kalbarri during Sunday afternoon, then extend further south towards Lancelin and inland into the southern Gascoyne and the Central Wheatbelt late Sunday and early on Monday morning.


Destructive winds with gusts to 150 kilometres per hour are forecast to occur closer to the centre of Seroja as it moves across the coast and into adjacent inland parts. The most likely area to experience destructive wind gusts is on the coast between Geraldton and Denham. People near Denham may see gales as early as midday, tending to as early as dusk further south near Geraldton. The most likely time for onset of gales winds is mid to late afternoon near Denham, and during the evening or overnight near Geraldton.

Seroja will be moving fast, so weather conditions will deteriorate rapidly as it approaches.

Heavy to intense rainfall and flash flooding are likely close to the track of Seroja during Sunday and Monday.

 Abnormally high tides could cause minor inundation at the coast between Coral Bay and Lancelin, increasing to serious flooding in the Denham and Shark Bay region and near Kalbarri. Dangerous surf and beach erosion is expected between Denham and Geraldton.

The forecast path shown above is the Bureau's best estimate of the cyclone's future movement and intensity. There is always some uncertainty associated with tropical cyclone forecasting and the grey zone indicates the range of likely tracks of the cyclone centre.

Due to the uncertainty in the future movement, the indicated winds will almost certainly extend to regions outside the rings on this map. The extent of the warning and watch zones reflects this.
