How we know

Rain here

Last 3 days: Not unusual · Amber · Warm Weather Advisory; Amber · Advisory for Severe Lightning

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, 16:30.

Weather forecast (Department of Meteorology) · Amber · Warm Weather Advisory; Amber · Advisory for Severe Lightning

Amber · Warm Weather Advisory. For Northern, North-Central, Eastern, North-Western provinces and Monaragala and Hambantota districts.. Heat index, the temperature felt on human body is likely to increase up to ‘Caution level’ at some places in Northern, North-Central, Eastern and North-Western provinces and in Monaragala and Hambantota districts during the daytime. The Heat Index Forecast is calculated by using relative humidity and maximum temperature and this is the condition that is felt on your body. This is not the forecast of maximum temperature. It is generated by the Department of Meteorology for the next day period and prepared by using global numerical weather prediction model data. Effect of the heat index on human body is mentioned in the above table and it is prepared on the advice of the Ministry of Health and Indigenous Medical Services. Issued 9 Oct, 16:00 · Valid until 11 Oct, 00:00.
Amber · Advisory for Severe Lightning. For Western, Sabaragamuwa, Central, Uva, North-western, Southern provinces and Anuradhapura, Mannar districts.. Thundershowers accompanied with severe lightning are likely to occur at several places in Western, Sabaragamuwa, Central, Uva, North-western and Southern provinces and Anuradhapura and Mannar districts. There may be temporary localized strong winds during thundershowers. General public is kindly requested to take adequate precautions to minimize damages caused by lightning activity. Issued 9 Oct, 11:00 · Valid until 10 Oct, 01:00.
Forecast issued 9 Oct, 14:00
Showers or thundershowers will occur in the most part of the island after 1.00 p.m.
Covers Moneragala on this road: 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.
Covers Moneragala on this road: 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.

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.

River basins this division lies in

Gal Oya basin

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.

Irrigation Department gauges on these rivers

Padiyathalawa, an Irrigation Department gauge 15.5 km downstream (158 km² upstream): 2.2 mm in the 24 hours to 9 Oct, 08:30 (Light); 0 mm in the 3 hours to 9 Oct, 21:10.
River level 0.07 m · Below Alert · steady over about 3 hours (Department’s thresholds: Alert 4, minor flood 4.5, major flood 6 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.
