While northern climates get a significant amount of extreme winter weather, it can affect regions throughout North America. Before winter weather strikes, review and revise your crisis communication plan. Determine the length of time for specific actions as detailed in the plan. Set a timeline for the order in which actions need to be put into effect. Establish protocols to test all procedures and equipment on a regular basis. Periodically test the readiness of your mass notification system. Communicate regularly with the public about extreme winter weather preparedness and issue appropriate safety recommendations
