WEEKLY AFRICAN WEATHER HAZARDS ASSESSMENT STATEMENT APRIL 3 - 9, 2003 DISCUSSION: 1) Long-term dryness continues across southern Mauritania resulting in poor pasture conditions and low water levels. New reports this week indicate that similar conditions exist in northern Senegal. Farmers are struggling as cattle are being moved southward towards The Gambia. The seasonal rains should start around the first of July. 2) Dryness throughout recent years has resulted in poor pasture conditions and low water supplies across north-central Ethiopia, and adjacent portions of Eritrea and Djibouti. However, seasonal rainfall has started across central Ethiopia and in more isolated events across the eastern pasture lands. The drought hazard has been scaled back in the east and south, but below normal conditions continue to exist in portions of southern Eritrea, Djibouti, eastern and central Ethiopia, Somalia, and northern Kenya. 3) Below normal rainfall totals in Guinea have resulted in low reservoir levels, which aid in the generation of hydro-electric power. Improvement is expected during the middle to end of this month. 4) Saturated conditions along the boarder of Mozambique and Tanzania and the eastern coast of Madagascar could lead to isolated areas of flooding as heavy rains are forecast to continue over the next several days. Flood prone areas should be monitored closely as convective showers could bring weekly totals greater than 100 mm. 5) Poor rains throughout portions of Botswana, South Africa, Mozambique, and Zimbabwe has resulted in lower than normal crop yields for much of the highlighted region. Rain-free days over the next month should actually help farmers as they begin to harvest the surviving crops. A hydrological assessment will be performed for the upcoming dry season as winter wheat will need irrigation and for the availability of drinking water. 6) Significant rainfall has fallen over Tanzania and southern Kenya, which should help alleviate some of the short term dry conditions. However, the area highlighted should continue to be monitored closely as the most recent forecast rains have not verified. Numerical models also indicate that the rains for the upcoming week will be below normal. Author: Kevin B Laws
