Global Weather Hazards Summary, May 12 - 18, 2017
Recent seasonal rainfall helps partially alleviate abnormal dryness in East Africa
Despite rainfall during early March, significant long-term moisture deficits remain throughout central and eastern Madagascar due to very poor rains earlier in the season.
Inconsistent rainfall since late December have led to moisture deficits and deteriorating ground conditions across many parts of western Angola.
Below-average rainfall accumulations since late February have resulted in moisture deficits, which have already negatively impacted agricultural and pastoral activities in many parts of southern South Sudan, Kenya, Ethiopia, southern Somalia, and northern Tanzania.
The onset of heavy rains last week resulted in flooding in parts of Kenya. Continued rains may trigger additional floods and elevate river levels.
Several consecutive weeks of below-average rainfall has led to early season moisture deficits in parts of Ghana.
Shabelle river levels have been rising since late April, creating a high risk for flooding along the middle and lower portions of the basin. Additional seasonal rainfall next week is expected to sustain the risk.
