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.

×Rain here
Last 24 hours: Unusual here (3 days a month)
- Last 24 hours: among the wettest 10% of 24-hour periods since 2000 in 10.
- 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, 16:30.
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: Not signalled
- Next day: unusually heavy rain is not signalled for the divisions on this road. (10 Oct, 05:30 to 11 Oct, 05:30)
- Next 3 days: unusually heavy rain is not signalled for the divisions on this road. (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.

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.

Irrigation Department gauges on these rivers
- Siyambalanduwa, an Irrigation Department gauge 14 km upstream (291 km² upstream): at least 7.3 mm in the 24 hours to 9 Oct, 08:30 (2 hourly readings missing); 1.3 mm in the 3 hours to 9 Oct, 20:02.
River level 0.57 m · Below Alert · rising over about 3 hours (Department’s thresholds: Alert 4.5, minor flood 6, major flood 7 m)
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.
