A major state of emergency has been declared across Australia's Northern Territory as Tropical Cyclone Helena intensifies to a category three system, posing a severe threat to coastal communities.
Mass Evacuations Underway
Authorities have initiated large-scale evacuations in low-lying areas of Darwin and surrounding regions, with emergency services warning residents to prepare for destructive winds exceeding 170km/h. The cyclone is expected to make landfall within the next 24 hours, bringing catastrophic weather conditions.
Emergency Services on High Alert
Northern Territory Chief Minister Eva Lawler announced the emergency declaration during a press conference, stating: "This is a severe weather event that requires immediate action. We are mobilising all available resources to protect communities in the cyclone's path."
Emergency shelters have been established across the territory, with residents urged to secure properties and prepare emergency kits containing essential supplies.
Transport and Infrastructure Impacts
The developing situation has already caused significant disruption:
- Multiple flights in and out of Darwin International Airport have been cancelled
 - Schools and government buildings across the territory will remain closed
 - Emergency services are conducting door-to-door checks in vulnerable communities
 
The Bureau of Meteorology has warned of potential storm surges and flash flooding, particularly in coastal areas where tidal conditions may exacerbate the situation.
Community Response and Preparedness
Local residents are taking emergency warnings seriously, with supermarkets reporting increased demand for essential supplies including water, batteries, and non-perishable food items.
Emergency authorities advise residents to:
- Stay informed through official weather channels
 - Secure outdoor items and prepare properties
 - Have evacuation plans ready if living in flood-prone areas
 - Check on vulnerable neighbours and community members
