WEEKLY AFRICAN WEATHER HAZARDS ASSESSMENT NOVEMBER 14, 2002 DISCUSSION: 1) An organized convective system is currently located to the northeast of Madagascar and is forecast to move west-southwestward during the next week. This storm has a strong potential to affect northern Madagascar, where locally heavy rains could be produced. Forecast models are not yet decided upon whether the storm will continue moving to the west, impacting Tanzania or Mozambique, or begin moving to the south, skirting the eastern Madagascar coast. Currently, the later forecast is more likely, but nothing can be ruled out. 2) A low pressure system will produce locally heavy rainfall, possibly exceeding 50 mm, over parts of northern Morocco and northwestern Algeria during November 14-16. Strong winds may accompany the heavier squalls, and local small-scale flooding may occur. Toward the end of the week around November 19, another system may affect the area and bring locally heavy rains to northwestern Morocco. 3) As shown from adequate river and reservoir levels in the upper Senegal Basin and favorable irrigation for recently resown crops, hydrological dryness has eased throughout much of Senegal. These moderate conditions are due to semi-sustained rainfall that occurred throughout parts of Senegal in August. However; rains were not as favorable throughout southern agricultural areas of Mauritania. Hydrological drought remains in this area and will not be relaxed until rains begin during next year's monsoon season. 4) Southern coastal areas of Cote d'Ivoire have received beneficial rainfall during the past few weeks and additional precipitation is expected during the next seven days. Soil moisture indices also show that the region's hydrological conditions are improving, but improvement further north has been slower to occur. Here, climatological dryness has set in, and little additional rainfall is forecast during the next weeks. Major hydrological problems are not expected to continue throughout the remainder of the year. 5) Severe hydrological drought continues regionally throughout parts of central and northern Ethiopia due to late-starting and sporadic rainfall during the previous seasons. Rainfall was lighter than normal toward southwestern Ethiopia as well, though conditions are not as severe as further northeast. Author: Timothy Love
