Bureau of Meteorology Removes 'Black' Warning Scale Amid Severe Storms. Jeremy Zakis discusses how the Bureau of Meteorology (BOM) launched a confusing new website during one of the Eastern Coast's worst storm seasons. They controversially removed the color "black" from the weather radar scale, which previously denoted the most severe weather, including heavy hail and flooding. When a major Queensland storm hit with only "red" warnings, people were unprepared, resulting in extensive property damage. Meanwhile, Queensland is facing highly unstable conditions, including rare reported water spouts and a tornado watch along the coastline.
