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.
Daily-history gaps are unknown, not dry: suspect or incomplete observations are not plotted. Event subtotals restart after a gap and are not complete storm totals. Original observations remain stored.
Choose a layer to see recorded events alongside the chart.
Explore recorded river changes and compare events after drier or wetter weeks.
Comparisons use complete past observations, including events with little rise. Ground wetness is estimated from preceding rainfall.
