Coverage shows valid readings received out of the expected 15-minute observations. Gaps may understate rainfall and are not treated as dry weather.

Water fills show relative rainfall, not flood risk. Hourly cards use rainfall intensity; 24 hours uses recorded wet-day percentiles; longer totals use estimated seasonal pace for the elapsed period. Grey means there is insufficient coverage or history for a comparison.
