Though not entirely a tekkie technology, PAGASA’s Yellow, Orange (previously Green but changed due to confusion and complaints from the thinking and highly-critical public – everyone was accustomed of knowing that Green means Go just like in the traffic lights) and Red – definitely could save lives.
That monsoon or “Habagat” struck the Philippines by surprise and caught everyone flat-footed! Floods brought destruction to both properties and lives thus was similarly compared to be worst than the “Ondoy” floods of 2009. August 7 was the start of a week-long rain that submerged the whole of Metro Manila declaring a State of Calamity on every city!
Be sure to know these colors by heart and sight!
