Global Alert System for cetacean stranding

Given the different parameters involved in issuing these alerts, I'm working on a color-coded worldwide Marine Animal Disturbance Alert system to make it simpler, more accurate and easier to follow. Inputs such as migration and habits need to be taken into consideration. Also, meteor airbursts of all energy outputs, heights and fireballs of all varieties need to be taken for what they are, diverse. Because this is relatively new, as in the last couple of years, new situations have come along that challenge what I want to portray in the alert issued, so this will be easier and more accurate. This new system will be shown like the example below (not the current situation) and will be presentable once software is involved. I gather this will change as it evolves. I will also issue dates to coincide with alert length, because cetaceans can come ashore many months after injury. This in itself can be confusing when events overlap.

Low - Green

Moderate - Orange

High - Yellow

Extremely High - Red
