Seasonal precipitation predictions in Desert Locust winter/spring breeding areas (December 2021 – May 2022)


Due to the recent intensification of La Niña, dry conditions are expected to continue in the Horn of Africa that will restrict current breeding by Desert Locust. Drier than normal conditions expected in the winter breeding areas along both sides of the Red Sea and Gulf of Aden will limit breeding from now until March except for slightly wetter conditions over the northern Red Sea in December. In the spring breeding areas, early rains could occur in the interior of the Arabian Peninsula during February followed by slightly wetter conditions there as well as in southwest Iran and Pakistan during April and May. In East Africa, slightly wetter than normal conditions could develop in March and April, coinciding with the Long Rains season.
