Continued heavy rainfall causes ooding in Ethiopia, Sudan, and South Sudan

Africa Weather Hazards

  1. Below-average rainfall since mid-May has led to abnormal dryness across eastern Uganda and southwestern Kenya. Moisture deficits are likely to negatively impact cropping and Pastoral activities.

  2. Repeated weeks of very heavy, above-normal rains have oversaturated the ground in parts of Ethiopia, Sudan, and South Sudan. More heavy rain during the next week is likely to cause further flooding.

Central Asia Weather Hazards

Temperatures

Below-normal temperatures (1-5°C) were recorded across most of Kazakhstan, Turkmenistan, and Uzbekistan from July 9 to 15, while near- to above-normal temperatures prevailed across the remainder of the region. Next week, the GFS model indicates that most areas will experience seasonal temperatures with maximum temperatures ranging from lower 30°C over northern Kazakhstan to above 40°C across the hottest locations of Afghanistan, Turkmenistan, and Uzbekistan.

Precipitation

Widespread rain fell for the second consecutive week across northern Kazakhstan with many gauges recording more than 25mm, and a maximum amount of 76mm.

Due to the two weeks of beneficial rainfall, the abnormal dryness hazard previously posted for northern Kazakhstan is removed for this week’s hazards. Heavy to excessive rainfall (locally more than 150mm), associated with the Indian monsoon, was recorded in northern Pakistan this past week.

During the next week, additional rainfall (10-50mm) is expected across northern Kazakhstan. Locally heavy rain capable of triggering flash flooding is expected to con nue over northern Pakistan.

Central America and the Caribbean Weather Hazards

  1. Abnormal dryness observed over northern Dominican Republic.
