As a result, people and businesses relying on NWS warnings directly, or all other known weather sources that simply distribute NWS tornado warnings, had NO NOTICE of the imminent life-threatening emergency before the tornado touched down.
Government cell phone alerting (wireless emergency alerts) would not have been triggered, outdoor sirens would not have been activated, and other emergency notifications from other agencies may not have been issued, as those notification methods depend upon National Weather Service warnings. Only those systems based on AccuWeather Warnings, including National Weather Service warnings but supplemented by the expertise of AccuWeather's Expert Storm Warning meteorologists, would have been activated.
More than 100 times every year, AccuWeather has been documented as providing more accurate, more advanced notifications of significant and extreme weather events that impact businesses and threaten the health, welfare and lives of individuals. AccuWeather has proven to be the most accurate source of weather forecasts and warnings.
This is an additional example of the many weather events where AccuWeather provided forecasts with proven Superior AccuracyTM and impact descriptions helping people, communities and businesses, to better prepare and stay safer.
