IGEBU iyo ICPAC oo digniin uga bixiyay roobab xooggan iyo halista daadadka Burundi
Xilliga 27 Oktoobar–3 Noofambar 2026 ayaa la tilmaamay mid halis ah, iyadoo roobab ka badan 200 mm la saadaalinayo qaybo ka mid ah gobollada Mugamba, Migwa, Kirimiro, Bweru iyo Buyogoma.
Institut Géographique du Burundi (IGEBU) iyo ICPAC ayaa saadaaliyay roobab ka sarreeya caadiga inta lagu jiro 27 Oktoobar–3 Noofambar 2026, iyagoo digniin uga bixiyay halista daadadka meelaha hooseeya, gaar ahaan Imbo iyo Bujumbura.
Saadaasha roobabka ee IGEBU iyo ICPAC
IGEBU waxay horraantii Agoosto soo saartay saadaasha roobabka xilliga Sebtembar–Diseembar 2026, taasoo muujisay suurtagalnimada badan ee roobab ka sarreeya caadiga Burundi oo dhan. Warqaddeeda toddobaadle ah ee 27 Oktoobar–3 Noofambar 2026 waxay saadaalisay roobab ka badan 200 mm qaybo ka mid ah Mugamba, Migwa, Kirimiro, Bweru iyo Buyogoma, iyo roobab 100 ilaa 200 mm dhulka kale. Saadaasha ICPAC ee isla xilligaas waxay xaqiijisay in roobab ka sarreeya caadiga la filayo Burundi iyo dalalka deriska ah.
Meelaha halista ugu badan iyo saameynta la filayo
Roobabka la filayo waxay khatar weyn ku yihiin meelaha hooseeya ee daadadka u nugul, gaar ahaan Imbo oo ay ku jirto Bujumbura, halkaas oo magaaloobidda iyo qulqulka biyaha oo xaddidan ay kordhin karaan daadadka dusha. Roobabka xooggan ee Mirwa waxay keeni karaan biyo qulqula oo u soo jeeda bannaanka Imbo, taasoo kordhin karta heerka webiyada iyo halista daadadka webiga. Saameynta la filayo waxaa ka mid ah daadad guryo, waddooyin iyo kaabayaal dadweyne, dhul beereed oo biyo qaata, iyo barakaca qoysas nugul.
Khataraha caafimaadka iyo baahida la socodka joogtada ah
Carrada qoyan ee jiirada sare waxay kicin kartaa dhul-go'yo, kuwaas oo xannibi kara marinnada biyaha oo sii xumeeya daadadka hoose. Daadadku waxay wasakheyn karaan ilaha biyaha oo kordhin karaan halista cudurrada biyaha laga qaado, sida daacuunka iyo cudurrada shubanka, iyadoo uu socdo cudurka daacuunka. IGEBU iyo ICPAC waxay xuseen in la socodka joogtada ah ee saadaasha qaranka iyo tan gobolka uu muhiim u yahay si loo hagaajiyo bartilmaameedka juqraafi ee diyaargarowga waqtiga leh.
IGEBU and ICPAC forecasts point to heavy rain in Mugamba, Migwa, Kirimiro, Bweru and Buyogoma, with low-lying Imbo areas and Bujumbura flagged as priorities.
Burundi's national forecaster and a regional climate centre expect above-normal rainfall from 27 October to 3 November 2026, with flooding possible in low-lying areas, including parts of Bujumbura and the Imbo region.
What the national and regional forecasts show
The Institut Géographique du Burundi (IGEBU) released a seasonal forecast for September–December 2026 in late August, indicating an increased likelihood of above-average rainfall across Burundi. Its weekly bulletin valid from 27 October to 3 November 2026 forecasts more than 200 mm in parts of Mugamba, Migwa, Kirimiro, Bweru and Buyogoma, and 100 to 200 mm elsewhere. ICPAC's regional forecast for the same period also indicates above-normal rainfall in Burundi and neighbouring countries.
Where the risk is concentrated
IGEBU expects above-normal rainfall in all natural regions and flags an explicit risk of flooding in low-lying areas. The main concerns are the high-rainfall zones it identified and low-altitude areas, particularly flood-prone parts of Imbo and Bujumbura. Heavy rain on the sloping Mirwa region may send surface runoff toward the Imbo plains, raising river levels and the risk of riverine flooding downstream.
Anticipated impacts and the need for monitoring
Possible impacts include flooding of homes, roads and public infrastructure, inundation of farmland, disruption of transport and access to essential services, and displacement of vulnerable households. Saturated soils on steep slopes may trigger landslides, and flooding may contaminate water sources, raising the risk of cholera and diarrhoeal diseases amid an ongoing cholera epidemic. In Bujumbura, intense rain may overwhelm drainage systems. Continued monitoring of national and regional forecasts is needed to refine targeting and support timely preparedness.
