Solid start

Simple, quick and effective forecasts. It’d be nice to have the flag scales as a reference and support metric measurements, though.

Response from developer

I have been considering adding an additional function for the user to establish what they want the WBGT ranges to be…give flexibility. As it stands, the flag conditions are as follows: WBGT 79.9 and Below - No Flag WBGT 80 to 84.9 - Green Flag WBGT 85 to 87.4 - Yellow Flag WBGT 87.5 to 89.9 - Red Flag WBGT 90 and Greater - Black Flag Thank you for your feedback! Jim
