• Last 24 hours: among the wettest 5% of 24-hour periods since 2000 in Thanamalvila.
• Last 3 days: among the wettest 10% of 3-day periods since 2000 in Thanamalvila, Haldummulla, Haputale, Welimada.
• Last 7 days: among the wettest 10% of 7-day periods since 2000 in Haldummulla, Haputale.
• 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, 02:30.

• NBRI's warning stays in force after rain eases.
• Department of Meteorology, Irrigation Department and NBRI automatic gauge readings, passed on as published. Met gauge sites are approximate.

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, Sooriyawewa, Lunugamvehera, Thanamalvila +4 (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, Sooriyawewa, Lunugamvehera, Thanamalvila +4 (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.
