About the Kurunegala–Ella road
The fastest road we know from Kurunegala to Ella is 189 km, about 5 h 10 min, via Digana, Badulla.
Main roads on it: Kandy-Mahiyanganaya Road (50 km), Badulla-Mahiyanganaya Road (33 km), Kandy-Kurunegala Road (22 km).
We show 3 roads between them, fastest first.

Past NBRI bulletins
Most often listed on this road, in the 41 NBRI bulletins we have passed on since Sun 20 Sept: Thumpane (22), Udadumbara (19), Medadumbara (12).
A record of past bulletins, not a forecast. Not being listed doesn’t mean safe.
Steep terrain
About 20 km of it runs through steep terrain (slopes over 30° beside the road). The longest stretch is between Hunnasgiriya and Ududumbara.
Terrain beside the road, from a satellite elevation model: not the road’s gradient and not a landslide hazard rating.
How to read this
- Not an official service. NBRI’s warnings are passed on as issued.
- Rain levels compare each division with its own satellite record since 2000. Satellites can miss heavy local downpours.
- Gauge sources: Department of Meteorology and Irrigation Department gauge readings, passed on as published. Met gauge sites are approximate. Compared with each division's own satellite record since 2000. This is not a warning and does not replace NBRI's levels. Satellites can miss heavy local downpours, so it never means a road is safe. Satellite data up to 10 Nov, 04:30. Checked Tue 10 Nov, 10:20.

Rivers and basins come from our own map of Sri Lanka’s river network. Flow direction, where shown, is worked out from the height of the land. This is orientation only, not a flood warning.
The area draining to a crossing is worked out from a terrain model (about 90 m cells) and is approximate. The rain over it is the satellite average for that same area, against its own record since 2000. Areas under about 150 km² are smaller than the satellite can see, so they show no rain.
River levels are the Irrigation Department’s own readings at its gauge, against its own thresholds. This is not a flood warning: flood warnings come from the Irrigation Department and DMC.

Satellite estimate
- Last 3 days: among the wettest 5% of 3-day periods since 2000 in Kurunegala, Weerambugedara, Polgahawela, Homagama +10.
Rain outlook (computer model) · Next day: Chance of a rare wet day
- Next day: a chance of a wet day of the kind that comes about 1–2 days a month in Kurunegala, Weerambugedara, Polgahawela, Narammala +9 (the wettest 5% of days there; several times the usual chance). (10 Nov, 05:30 to 11 Nov, 05:30)
- Next 3 days: a chance of a wet day of the kind that comes about 1–2 days a month in Kurunegala, Weerambugedara, Polgahawela, Narammala +13 (the wettest 5% of days there; several times the usual chance). (10 Nov, 05:30 to 13 Nov, 05:30)
- "Not signalled" never means dry or safe. This is a computer model, not a warning, and it never changes NBRI's levels. Like the satellite, it reads hill-country rain low and can miss heavy local downpours.
- ECMWF ensemble forecast (open data, CC BY 4.0), run 9 Nov, 17:30, compared with each division's own satellite record.

Rivers and basins come from our own map of Sri Lanka’s river network. Flow direction, where shown, is worked out from the height of the land. This is orientation only, not a flood warning.
The area draining to a crossing is worked out from a terrain model (about 90 m cells) and is approximate. The rain over it is the satellite average for that same area, against its own record since 2000. Areas under about 150 km² are smaller than the satellite can see, so they show no rain.
River levels are the Irrigation Department’s own readings at its gauge, against its own thresholds. This is not a flood warning: flood warnings come from the Irrigation Department and DMC.
