FEWS NET FAMINE EARLY WARNING SYSTEMS NETWORK GLOBAL Weather Hazards Summary June 17-23, 2016 Abnormal dryness in southern Haiti and parts of East Africa Africa Weather Hazards Flooding Abnormal Dryness Drought Severe Drought Tropical Cyclone Potential Locust Outbreak Heavy Snow Abnormal Cold Abnormal Heat Seasonally Dry 1. Despite enhanced rain over some areas of the 1 Gulf of Guinea over the past few weeks, low and erratic rainfall during April and May has persisted and led to growing moisture deficits over Liberia and parts of Sierra Leone. 3 2 2. Low and infrequent rainfall since late March has resulted in drought across parts of southeastern Kenya and northeastern Tanzania. The potential for recovery remains unlikely as suppressed rain is forecast during the next week for coastal regions, and areas inland are now climatologically dry. 3. Consistently below-normal rainfall over the past 4 weeks has resulted in abnormal dryness for portions of Uganda and western Kenya. This pattern has resulted in low soil moisture and poor vegetation health index values. FEWS NET is a USAID-funded activity.

Flooding Abnormal Dryness Drought Severe Drought Tropical Cyclone Potential Locust Outbreak Heavy Snow Abnormal Cold Abnormal Heat Temperatures Above-normal temperatures were observed across much of the region from June 5 to 11, with the largest positive anomalies of 5 to 7 °C across southern Kazakhstan, Kyrgyzstan, Turkmenistan, Uzbekistan, and northern Afghanistan. The hottest temperatures were observed across western Afghanistan, Turkmenistan, and Uzbekistan, where maximum temperatures ranged from 40 to 47 °C. During the next week, seasonal temperatures are predicted across most of Central Asia. Precipitation Widespread showers and thundershowers affected the northern half of northern Kazakhstan from June 5 to 11, with many locations in north-central Source: FEWS NET/NOAA Kazakhstan receiving more than 25 mm. The rainfall since late May ended the short-term dryness that had previously developed across northern Kazakhstan. The CPC unified gauge analysis depicts 30-day precipitation surpluses across nearly the entire region. Scattered showers and thundershowers (locally more than 25 mm) are forecast to continue throughout Central Asia during the next week with the most widespread rainfall across northern Kazakhstan. Central America and the Caribbean Weather Hazards 1. Thirty-day rainfall deficits have persisted across portions of Guatemala, Honduras, and El Salvador despite increased rain during the past week. Heavy rain is forecast to continue during the next week and is expected to help alleviate dryness over many local areas. 2. The risks for flooding remain high across the Pacific and central regions of Guatemala as torrential rain is forecast to continue during the upcoming week. 1 2 3. Poorly-distributed rain since early May has resulted in abnormal dryness throughout the southern departments of Haiti and southwestern Dominican Republic. Limited amounts of rain are forecast during the next week, potentially worsening dryness over the region.

The uneven distribution of rainfall over the past four weeks has already negatively impacted conditions on the grounds of many local areas. Recent crop performance models and vegetation health indices have indicated further degradation in conditions over areas of southern Haiti. During the next week, light and below-average rain is forecast to continu. Only localized areas of central Haiti and central Dominican Republic are expected to receive moderate showers, while light to no rain is forecast elsewhere. The forecast continuation of insufficient rain could further negatively impact the first rainfall season’s cropping activities.
