Alert line
Warning line
Danger line
NORMAL
Alert threshold යට — routine monitoring.
ALERT
First threshold — forecasts/upstream rain watch.
WARNING
Significant rise — local guidance අනුව prepare.
DANGER
Highest threshold — DMC/local authority instructions follow.
මෙයින් අදහස් වන්නේ
Water level metres — gauge point river height, street flood depth නොවේ.
NORMAL = alert threshold යට. ALERT = first threshold — monitoring, public danger necessarily නොවේ.
WARNING/DANGER station-specific. One river WARNING another river same risk නොවේ.
Remarks/timestamps upstream feed. History unavailable නම් sparklines degrade gracefully.
අප claim නොකරන දේ
Gauges preparedness input එකක් — DMC bulletins/local warnings replace නොකරයි.
