From Fox Weather:
On a day with many dangerous severe storms in the forecast, critical information on Kansas City‘s highway traffic system has faded to black, leaving thousands of drivers in the dark.
A cyberattack forced the city’s traffic information system, known as KC Scout, to take immediate action Thursday and shut down all its systems as a protective measure. As a result, real-time cameras and information boards are currently not functioning on Saturday when all modes of severe weather, including potentially strong tornadoes and large hail, will be possible. Flash and river flooding are also likely, which could inundate some city roads.
