How the score is calculated
The score starts at 8. It adds points from recorded affected, deaths, displaced and casualty counts, plus terms found in the story title, event type or status. For each count, only its highest matching band is used.
- Affected people
- 1–999: +5 · 1,000–9,999: +12 · 10,000–99,999: +20 · 100,000–999,999: +28 · 1 million+: +35
- Deaths
- 1–9: +8 · 10–99: +14 · 100–999: +22 · 1,000+: +30
- Displaced people
- 1–9,999: +6 · 10,000–99,999: +12 · 100,000+: +18
- Casualties
- 100 or more: +8
- Story wording
- +10 for terms such as catastrophe, famine, war, conflict, major earthquake, mass casualty or critical. Otherwise, +5 for active, ongoing, emergency, outbreak, cyclone or hurricane.
Score bands: Watch 0–24 · Moderate 25–49 · High 50–74 · Critical 75–100. Scores are capped at 100. Missing or unparseable figures add no points.

Situation
Heavy rains on 2 August in an IDP camp in Bama LGA partially damaged or destroyed at least 475 shelters, affecting some 2,481 IDPs. The rains, which lasted four hours the day before, left areas of the camp submerged in water. Food stocks and non-food items such as mats, children’s learning materials and clothing were also damaged or destroyed. Humanitarian partners conducted a rapid assessment on 3 August, as well as relocated 96 shelters to dry land and deployed 20 trucks of sand to reinforce shelters and fill sandbags to hold back the flood waters. The Nigerian Hydrological Services Agency warned that severe flooding would affect most parts of the country throughout August and September. Partners have been prepositioning food and other items to mitigate the effects of the rainy season in Borno, Adamawa and Yobe states. Several camps, such as the one flooded in Bama town, started as spontaneous settlements in flood-prone areas. Humanitarian partners are advocating for land to be allocated to relocate some of these camps. ( OCHA, 11 Aug 2020 ) On 5-6 September, heavy rain and associated flooding affected Kano State (northern Nigeria), leading to fatalities, displaced people and damage. Media report that 2 people died and more than 5,000 houses were destroyed in Danbatta Area, 2 fatalities and over 200 damaged houses occurred in Rogo Area. Flooding was reported across more than 20 Local Government Areas of Kano State, and a number of people have been displaced. Recent flooding across Jigawa, Kano, Kebbi and Sokoto States in northern Nigeria have caused around 30 fatalities and damage to thousands of homes and crop fields. Moderate to heavy rain is forecast over central and northern Nigeria on 7-8 September. ( ECHO, 8 Sep 2020 )
