Australia: Adverse weather forecast across far southern parts of Western Australia through at least April 28

Event

Heavy rainfall and strong winds are forecast to continue across far southern areas of Western Australia through at least April 28. A cold front in Central Wheat Belt District is forecast to continue to track southeast April 27. Severe thunderstorms in the Goldfields are likely to extend into the South East Coastal and Eucla districts over the coming hours.

The Australian Bureau of Meteorology (BoM) has issued a severe thunderstorm warning for heavy rainfall and damaging winds for parts of Goldfields, Eucla, and South East Coastal districts. Strong wind warnings are in place over the Esperance and Eucla coasts April 27 and over the Leeuwin, Albany, Esperance, and Eucla coasts April 28.

Hazardous Conditions
Sustained heavy rainfall could trigger flooding in low-lying communities near rivers, streams, and creeks. Urban flooding is also possible in developed areas with easily overwhelmed stormwater drainage systems. Sites located downstream from large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall. Landslides are possible in hilly or mountainous areas, especially where the soil has become saturated by heavy rainfall.

Authorities could issue mandatory evacuation orders for flood-prone communities over the coming days. Disruptions to electricity and telecommunications services are possible where significant flooding or landslides impact utility networks.

Transport
The severe weather will likely contribute to transport disruptions throughout the region. Traffic and commercial trucking delays might occur along regional highways. Flooding downpours could inundate some low-lying roads in areas with poor drainage. Strong winds might also pose a hazard to high-profile vehicles. Hazardous weather conditions might cause flight delays and cancellations at airports in the affected region.

Advice

Monitor local media for updated emergency and weather information. Seek updated information on weather and road conditions before driving or routing shipments through areas where severe weather is forecast. Plan accordingly for potential delivery delays if routing shipments by truck through the affected area. Do not attempt to drive through flooded areas. Charge battery-powered devices in the case of prolonged electricity outages.
