Federal forecasters said the updated alerts will apply to tornado and severe thunderstorm warnings only. Under the current system, meteorologists issue tornado and severe thunderstorm warnings to zones often dictated by different governmental and regional boundaries. However, when targeted warnings are issued, those will be issued to the National Public Alerting System (also known as Alert Ready). Recent changes include a new colour-coded weather alert system and the completion of a new “state-of-the-art” weather radar network. Ramsahai said it’s believed the number of alerts for tornado and severe thunderstorm warnings could drop by up to 70 per cent because of the improvements.
