How to read this forecast
Each bar is the predicted Kp index for a 3-hour window. Color indicates storm level: cool blue (0-3) means quiet, amber (4) means mild storm, orange/red (5-6) means notable, deep red (7+) means severe.
If you're storm-sensitive, watch for days with several orange or red bars in a row. During those periods drink more water, cut caffeine, and avoid scheduling important decisions.
