Outside NBRI’s warning area
NBRI issues no landslide warnings for the districts this road crosses, so the bulletin says nothing about it. This is not a guarantee that the road is safe or open.

Last 3 days: Not unusual
- Rain over the last 7 days has not been unusual for the divisions on this route.
- 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 9 Oct, 15:30.
Weather forecast (Department of Meteorology)
- No Department of Meteorology advisory is in force.
- Forecast issued 9 Oct, 14:00
- Showers or thundershowers will occur in the most part of the island after 1.00 p.m.
- Fairly heavy falls above 75 mm are likely at some places in Western, Sabaragamuwa, Central, Uva, North-Western and Southern provinces.
- The general public is kindly requested to take adequate precautions to minimize damage caused by temporary localized strong winds and lightning during thundershowers.
- Misty conditions can be expected at some places in Western, Sabaragamuwa, Central and Uva provinces during the early hours of the morning.
- A forecast never lowers or replaces the NBRI landslide warning above.
- Forecast and advisories by the Department of Meteorology, Sri Lanka, as issued. LankaWatch is not an official service.
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 279 (the wettest 5% of days there; several times the usual chance). (10 Oct, 05:30 to 11 Oct, 05:30)
- Next 3 days: a chance of a wet day of the kind that comes about 1–2 days a month in 279 (the wettest 5% of days there; several times the usual chance). (10 Oct, 05:30 to 13 Oct, 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 Oct, 05:30, compared with each division's own satellite record.
None of these changes NBRI’s level.

Satellite rain over these basins
Rain over these basins in the last 7 days has not been unusual against each basin’s own record. That never means safe.
A whole-basin satellite average against that basin’s own record since 2000, not the area upstream of any one point. Satellites under-read hill rain. Not a warning.

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.
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.
