Winter Alerts 11/12
INDIANAPOLIS (WISH) — Winter Weather Preparedness Week rolls on Tuesday in Indiana.
One of the key focuses of the week is understanding the differences between winter alerts from the National Weather Service.
As a reminder, wind chill watches and warnings have been reworded to extreme cold watches, cold weather advisories, and extreme cold warnings. Below is a list of all the different types of winter alerts:
Watch/Advisory/Warning Process
When there is a chance of a winter storm, a watch will be issued from 2-4 days out. This signals the area to be prepared for hazardous winter weather.
A winter weather advisory goes in place when impacts are expected, but not to the level of a warning being issued. Alerts for these types of advisories are typically issued from 12-36 hours before the impacts start. In this advisory, a forecast that contains from 2-5 inches of snow, less than a quarter-inch of ice, less than 2 inches of sleet, blowing snow, or a combination of these will trigger this alert.
