Persistently belowaverage rainfall since August over several 1 bimodal areas of Côte d’Ivoire, Ghana, Togo, Benin, and Nigeria has led to an increase in moisture deficits and a degradation of ground conditions, resulting in drought. 3 2 4 2. Below-average rainfall since August has led to increased moisture deficits throughout several provinces in southern South Sudan and northern Uganda. Dry conditions stretch into Lake Victoria regions of western Kenya. 3. Poorly distributed rainfall has resulted in drought, which has severely impacted ground conditions and already led to livestock death across parts of north-central eastern Ethiopia. 5 Source: FEWS NET/NOAA 4. Heavy rains over the last 2 weeks have led to swelling rivers in Somalia and Southern Ethiopia. The Shabelle River and the Jubba River are forecast to be near or above flood stage. Flood risk is high for the middle and lower reaches of the Shabelle and moderate for the lower portions of the Jubba River. Additional forecast rain threatens to exacerbate the situation, maintaining the risk for river and flash flooding. 5. Erratic and poorly distributed rainfall over the past month has led to early-season moisture deficits in the sugarcane growing region of South Africa. Vegetation indices reveal that ground conditions are already degrading. FEWS NET is a USAID-funded activity.

Weather Hazards Summary October 30 - November 5, 2015 Central Asia Weather Hazards 1. A heavy snow hazard is posted over the highest elevations of Kyrgyzstan and Tajikistan as more heavy snow is forecast over the regions during the next week. Temperatures Below-normal temperatures (1 to 6 °C) persisted for the second consecutive week across Kazakhstan, Turkmenistan, and Uzbekistan. Freezing temperatures occurred as far south as southern Turkmenistan during the past week, with minimum temperatures falling to -19 °C across northern Kazakhstan. The GFS model indicates that near to above-normal temperatures will return to Central Asia during the next week. Flooding Abnormal Dryness Drought Severe Drought Tropical Cyclone Potential Locust Outbreak Heavy Snow Abnormal Cold Abnormal Heat Precipitation During the past week, moderate to heavy precipitation occurred across most of Central Asia, with the largest Source: FEWS NET/NOAA amounts (more than 25 mm) observed across northern Kazakhstan, Kyrgyzstan, and eastern Uzbekistan. Snowfall depths continue to increase across the higher elevations of Kyrgyzstan, Tajikistan, and northeast Afghanistan. The CPC Unified Gauge analysis during the past 30 days indicates near to above-normal precipitation across the region. A relatively wet pattern is expected to continue with more heavy snow (locally more than 25mm, liquid equivalent) across the higher elevations of Kyrgyzstan, Tajikistan, and northeast Afghanistan. 3 Central America and the Caribbean Weather Hazards 1. Heavy and above-average rain has resulted in flooding and landslides over many local areas of Guatemala, Belize, El Salvador and Honduras during the past week. Forecasts indicate heavy rain is possible in Guatemala during the next week, which could exacerbate conditions on the ground and may trigger flooding. 1 2. Despite increases in rainfall over the past two weeks, rain has been below average in eastern Honduras and east-central Nicaragua over the past five weeks. The insufficient rain has led to moisture deficits, which have negatively impacted cropping activities over many local areas. 2 No Hazards Posted for Central America Flooding Abnormal Dryness Drought Severe Drought Tropical Cyclone Potential Locust Outbreak Heavy Snow Abnormal Cold Abnormal Heat 3. Poor rainfall distribution over the past several weeks has maintained abnormal dryness along southern coasts of Hispaniola and eastern Dominican Republic. Consistent and ample rain is required to eliminate deficits since the start of the second rainfall season.

Light to moderate rain prevailed elsewhere across the island. Over the past thirty days, rainfall anomalies have indicated moderate to large (50-200 mm) moisture surpluses across north-central Dominican Republic and northern Haiti but comparable rainfall deficits for the southern half of Haiti. Since the beginning of August, rainfall has been unevenly distributed both in space and time over Hispaniola, resulting in moderate seasonal deficits along the southern coasts of the island and eastern two-thirds of the Dominican Republic. Recent vegetation indices have indicated poor and degraded conditions over many local areas near the coasts, especially in western Haiti, and average to above-average conditions across the central portions of Hispaniola. Some improvement is being observed in western Haiti. During the next week, mostly near average average rainfall is forecast over Hispaniola. mmentsabout aboutthis thisproduct productmay maybe bedirected directedto [email protected] [email protected] or or 1-301-683-3424. 1-301-683-3424. mments ABOUT WEATHER HAZARDS Hazard maps are based on current weather/climate information, short and medium range weather forecasts (up to 1 week) and their potential impact on crop and pasture conditions.
