Before you go

About the Ohiya (Horton Plains)–Kurunegala road
The fastest road we know from Ohiya (Horton Plains) to Kurunegala is 160 km, about 4 h 50 min, via Pussellawa.
Main roads on it: Nuwara Eliya Road (51 km), Kandy-Kurunegala Road (22 km), Blackpool-Ambewela Road (13 km).
We show 3 roads between them, fastest first.
DS divisions on this road
It passes through 14 DS divisions in 4 districts, in travel order:

Past NBRI bulletins
Most often listed on this road, in the 41 NBRI bulletins we have passed on since Sun 20 Sept: Yatinuwara (27), Thumpane (22), Udunuwara (20).
A record of past bulletins, not a forecast. Not being listed doesn’t mean safe.
Steep terrain
About 10 km of it runs through steep terrain (slopes over 30° beside the road). The longest stretch is near Kothmale.
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, 05:30. Checked Tue 10 Nov, 10:50.

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.
