Is Kirulapone flooding?

Kirulapone, Colombo

Kirulapone flood risk right now: No estimate right now. This is an estimate from rain and official warnings, because no river gauge is close enough to use.

Flood estimate

No estimate right now

We cannot estimate Kirulapone right now: the nearest river gauge has no usable reading.

Details

How this estimate works

· Starts from the river gauge's own level and forecast, the same as the gauge page.
· Heavy rain here (50 mm in 6 hours or 100 mm in 24 hours) raises it by one step, never more.
· Your own street level, if you set one, and official warnings can raise it further.
· It never says flooding is happening: only a measurement can show that.

Rain map

It is around high tide now. Canals drain slowest for the next hour or so. Next high tide around 3:03 pm.

Sea level at the Kelani mouth is rising (reading 12:30 am). Canal levels: CUrW / SLLDC (pub.curwsl.org)

How water drains here

Water here drains south through the Kirulapone and Wellawatta canals and the Dehiwala canal straight to the sea. These canals rise and fall with the tide, so heavy rain at high tide drains slowly. The Kelani gauge does not decide flooding here.

No river gauge decides flooding here (the water goes to the sea, not the Kelani), so this page reads official warnings only. Rain and tide are shown as context.
