I. Introduction This dekadal climate early warning bulletin n°79 is done through the exploitation of spatial data collected from major international centres involved in day-to-day climate science, notably: the International Research Institute for Climate and Society (IRI) of the University of Columbia (USA); the National Oceanic and Atmospheric Administration (NOAA, USA); AccuWeather (American Weather Forecasting Agency, USA); the African Centre of Meteorological Applications for Development (ACMAD); Spatial data from 1979 to 2018, relating to Ocean Surface Temperature (OST) in the Atlantic and Pacific, El- Niño/La Nina episode intensities in the Pacific, rainfall and temperature from local stations. To this end, NOCC would like to express its gratitude to all these international Institutions as well as the DMN for the good will demonstrated in sharing the data. This bulletin highlights the historical climatic conditions from 1979 to 2018, as well as the climatic forecasts for all the five Agro ecological zones of Cameroon, for the period from 1st to 10th May 2021. This early warning brief further underscores the risks, threats and potential impacts expected in the different socio-economic development sectors of Cameroon. It also makes an assessment of the forecasts made for the previous dekad from 21st to 30th April 202 1. This dekad from 1st to 10th May 2021 will be characterized by the action of the Harmattan in the Sudano-Sahelian zone and the influence of the Monsoon over the rest of the national territory.

II. Forecast Summary II.1. For Temperatures II.1.1. Maximum Temperatures The following localities have a high probability of experiencing an increase in average maximum temperatures compared to historical averages for the same period from 1979 to 2018. They include: - Tibati and Mbakaou, in the Adamawa Region; - Mbalmayo, Yaounde, Eseka, Akonolinga, Obala, Mbandjock, Nanga Eboko, Monatele, Bafia, Nkoteng and Ngoro, in the Centre Region; - Yokadouma, Doume, Batouri, Mindourou, Lomie, Bertoua, Mintoum, Mbalam, Abong-Mbang, Ngoyla and Belabo, in the East Region; - Munkep, Furu Awa and Ako, in the North ; NB1: This dekad from the 1st to 10th May 2021 will be marked by significant risks of heat waves (number of successive days with temperatures above 30°C) in many localities in the (, Dembo, , Pita, Lagdo, Rey-Bouba, Tcholliré, Poli and ), Far North Region (Makary, Kousseri, Waza, Mora, Maga, Bogo, Maroua, Mindif, Kaele, Gamboura and Yagoua). II.1.2. Minimum Temperatures The following localities have a high probability of experiencing a decrease in minimum temperatures compared to the historical mean for the same period from 1979 to 2018. They include: - Gamboura, Maroua, Mora and Waza, in the Far North Region; - Poli, Touboro and Tchollire, in the North Region; - Ngaou Mbol, Kognoli, Kongolo, Yimbere, Ngaoundal, Ngaoundere, Tignere and Meiganga, in the Adamawa Region; - Betare-Oya and Garoua-Boulai, in the East Region; - Lolodorf, in the South Region; - , , , and , in the West Region; - Nkambe, Bali, Ndop, Fundong, Bamenda and Santa in the North West Region. NB2: This dekad from 1st to 10th May 2021 will be marked by an increase in the number of days with cold nights in some localities of the Far North (Waza, Maroua and Mora), North (Poli, Touboro and Tchollire), Adamawa (Yimbere, Ngaou Mbol, Kognoli, Kongolo, Ngaoundal, Ngaoundere, Tignere and Meiganga), East (Mbitom, Betare-Oya and Garoua-Boulai), the South (Lolodorf), the West (Dschang, Bazou, Bafoussam, Mbouda and Bafang) and the North West (Nkambe, Bali, Ndop, Fundong, Bamenda and Santa) regions.

II.2. For Precipitation The period from 1st to 10th May 2021 will be marked by a general increase in rainfall amounts in the Guinean High Savannah Zone. However, it will be more significant in the eastern and western parts of the zone. In addition, an increase in rainfall amounts will also be registered in the Bimodal Rainfall Forest Zone as well as in the Monomodal Rainfall Forest Zone. However, a general decrease in rainfall amounts will be registered in the Highlands Zone.

NB3: This dekad, from 1st to 10th May 2021 corresponds to

- the continuation of the short rainy season in the Bimodal rainfall forest zone (Centre, South and East regions);

- the continuation of the rainy season in the Highlands zone (West and North West regions) and in the Monomodal rainfall forest zone (Littoral and

South West regions).

-the extension of the dry season in the Sudano-Sahelian zone (Far North and North regions).

st th NB 4: This dekad from 1 to 10 May 2021 is favourable for the continuation of sowing in the Guinean High Savannah Zone, Adamawa Region.
