Jersey's emergency services will be practicing their response to a terrorist attack this week.
We're being assured 'Exercise Tempest' is a routine drill, and not in response to any specific threat.
Fire, Police and Ambulance will be involved in the major incident training on Wednesday (25 March).
It will start at La Collette at 9am and travel up to Fort Regent.
Islanders can expect too see a number of emergency service vehicles in the area.
Authorities say the purpose is 'to ensure Jersey’s emergency services can work together effectively during fast-moving, high-pressure incidents'.
