About the Bandarawela–Kurunegala road
The fastest road we know from Bandarawela to Kurunegala is 170 km, about 5 h 10 min, via Welimada, Gampola.
Main roads on it: Nuwara Eliya Road (51 km), Kandy-Kurunegala Road (22 km), Bandarawela-Welimada Road (20 km).
We show 3 roads between them, fastest first.
DS divisions on this road
It passes through 16 DS divisions in 4 districts, in travel order:
- Bandarawela
- Ella
- Haputale
- Welimada
- Nuwara Eliya
- Kothmale East
- Udapalatha
- Udunuwara

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 12 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, 07:30. Checked Tue 10 Nov, 13:10.

Heavy falls above 100mm are likely at some places in Western, Sabaragamuwa, Central and Uva provinces and in Galle and Matara districts. Strong gusty winds of 60–70 kmph and very rough sea conditions can be expected temporarily during thundershowers in the sea areas. Action Required: • Stop paddy and plantation work, outdoor sports and construction when storms approach. • Move into a substantial building or an enclosed hard-topped vehicle; do not shelter under trees, open huts, tents or bus halts. • Avoid open fields, hilltops, beaches, tanks, rivers and other water bodies. • Fishermen and small-boat operators should not go to sea and should return to shore early. • Avoid bathing, using wired phones and handling electrical appliances during thunder. • Avoid travelling on tree-lined roads and through flooded roads. • Follow flood warnings and landslide warnings. • Protect livestock, crops and property, and be ready to move to a safe shelter if advised. Damage Expected: • Widespread thunderstorms with frequent lightning, strong gusty winds and heavy rain. • Risk of injury or death for people in open areas such as paddy fields, plantations, playgrounds, beaches, and for people on boats. • Trees uprooted and damage to roofs of non-engineered houses, including tin and thatched roofs. • Localized flash floods and slope failures in vulnerable areas. • Power and communication interruptions and damage to electrical equipment. • Damage to crops, plantations and livestock. • Dangerous conditions for small fishing boats and craft. • Disruption to road, rail and air transport.

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 Embilipitiya, Welivitiya-Divithura, Karandeniya, Elpitiya +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 Bandarawela, Ella, Wellawaya, Thanamalvila +10 (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 Bandarawela, Ella, Wellawaya, Thanamalvila +14 (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.

Strong gusty winds of 60–70 kmph and very rough sea conditions can be expected temporarily during thundershowers in the sea areas. Action Required: • Stop paddy and plantation work, outdoor sports and construction when storms approach. • Move into a substantial building or an enclosed hard-topped vehicle; do not shelter under trees, open huts, tents or bus halts. • Avoid open fields, hilltops, beaches, tanks, rivers and other water bodies. • Fishermen and small-boat operators should not go to sea and should return to shore early. • Avoid bathing, using wired phones and handling electrical appliances during thunder. • Avoid travelling on tree-lined roads and through flooded roads. • Follow flood warnings and landslide warnings. • Protect livestock, crops and property, and be ready to move to a safe shelter if advised. Damage Expected: • Widespread thunderstorms with frequent lightning, strong gusty winds and heavy rain. • Risk of injury or death for people in open areas such as paddy fields, plantations, playgrounds, beaches, and for people on boats. • Trees uprooted and damage to roofs of non-engineered houses, including tin and thatched roofs. • Localized flash floods and slope failures in vulnerable areas. • Power and communication interruptions and damage to electrical equipment. • Damage to crops, plantations and livestock. • Dangerous conditions for small fishing boats and craft. • Disruption to road, rail and air transport. Issued 10 Nov, 12:45 · Valid until 11 Nov, 01:00.

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.
