@Naiyana4 Yes there no unhealthy level of SO2 in Hawaï right now: https://www.hawaiiso2network.com/ Which means that the SO2 concentration is below 0.10 ppm (part per million) 0.1 ppm is close to 300μg/m3 At 9:00 UTC Windy showed less than 100μg/m3, so this level was unhealthy. But at 12:00UTC, the figure raised to 400μg/m3 (With modified colors) Quite strange
