Tropical Cyclone Sean

Tropical Cyclone Sean is currently affecting Western Australia, having recently strengthened to a Category 3 storm. As of January 2025, it has been downgraded from Category 4 and is expected to weaken further as it moves over cooler waters. Heavy rainfall has been recorded, especially in Karratha, causing local flooding and prompting emergency alerts.

Formation of Cyclone Sean
Cyclone Sean developed on January 20, 2025, starting as a tropical disturbance and rapidly intensifying to Category 4. Key factors contributing to its formation included warm sea surface temperatures, a low-pressure system, and minimal vertical wind shear.

Causes of Tropical Cyclones

  • Warm Sea Surface Temperatures: Cyclones form in waters above 27°C.
  • Low-Pressure Area: A low-pressure zone is crucial for cyclone formation.
  • Coriolis Force: This causes the storm to rotate and organize.
  • Minimal Vertical Wind Shear: Stable wind conditions help the cyclone grow.
     

Structure of a Tropical Cyclone

  • Eye: The calm center with low pressure.
  • Eyewall: The area of strongest winds and heaviest rain.
  • Moisture and Updrafts: Warm air rising from the ocean forms clouds and drives the storm.
     

Effects of Tropical Cyclone Sean

  • Record Rainfall:
    Karratha recorded 274 mm of rain in 24 hours, the highest on record.
    Intense rainfall led to localized flooding.
  • Flood Risks:
    Flash floods were reported, triggering emergency alerts along the Pilbara Coast.
    Roads and homes were affected, but the cyclone did not make direct landfall, preventing major damage.
  • Community Disruptions:
    Emergency services carried out water rescues and dealt with power outages.
    Roads, including the North West Coastal Highway, were partially affected.
