Big Changes Ahead - North Dakota Blizzard - Winter Storm Rating Scale

I had a Category 5 dinner Sunday (Filipino food). This morning I woke up to a minor Category 3 headache. Maybe it's the seasons shifting gears?

We rank hurricanes and tornadoes on a scale from 1-5, why not winter storms? NOAA is testing an experimental WSSI scale (Winter Storm Severity Index) that has 5 levels. The forecast for much of North Dakota is "extreme" (Category 5) conditions from snow, ice and wind. "Life saving actions will be needed, extreme disruptions to daily life." Keep that in mind if your travels take you west in the coming days.
