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 10 Nov, 03:30.
Weather forecast (Department of Meteorology)
- No Department of Meteorology advisory is in force for Hambantota.
- Forecast issued 10 Nov, 05:30
- Showers or thundershowers will occur at times in the Northern province and in Trincomalee district.
- Showers or thundershowers will occur elsewhere in the island after 1.00 p.m.
- Heavy falls above 100mm are likely at some places in Western, Sabaragamuwa, Central and Uva provinces and in Galle and Matara districts.
- Covers Hambantota on this road: Showers may occur in the coastal areas of the Southern Province during the morning.
- 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 and in Galle, Matara and Kurunegala districts 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 Hambantota (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 Hambantota (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.
None of these changes NBRI’s level.

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.
