Details of Tropical Cyclone Seroja at 2:00 am AWST:
Intensity: Category 2, sustained winds near the centre of 110 kilometres per hour with wind gusts to 155 kilometres per hour.

Location: within 55 kilometres of 22.4 degrees South 109.6 degrees East, estimated to be 500 kilometres west northwest of Carnarvon and 750 kilometres northwest of Kalbarri.

Movement: southeast at 24 kilometres per hour.

Tropical Cyclone Seroja is moving towards the southeast and approaching the west coast of WA.

Seroja is expected to intensify a little during Sunday, possibly reaching Severe Category 3 intensity as it accelerates southeastwards towards the coast. It is then forecast to weaken back to Category 2 before it crosses the coast.

The cyclone should 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 Minilya Roadhouse and Kalbarri during Sunday afternoon, then extend further south towards Lancelin and inland into the southern Gascoyne and the Central Wheatbelt during Sunday evening and early on Monday morning.

DESTRUCTIVE WINDS with gusts to 150 kilometres per hour are forecast to occur close 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 on Sunday, tending to as early as dusk further south near Geraldton. The most likely time for onset of gales winds is mid to late Sunday afternoon near Denham, and during Sunday evening or overnight near Kalbarri and 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.
