Insufficient rain has led to drought in the Greater Horn

Africa Weather Hazards

  1. Locust outbreak has continued in western Mauritania. Breeding has extended to southern Western Sahara, where limited control operations are in progress, according to the Food and Agriculture Organization.

  2. Poor early season precipitation has resulted in increasing moisture deficits and deteriorating ground conditions throughout portions of Angola, southern DRC, and northern Zambia.

  3. Despite some increase in rainfall over the Greater Horn of Africa during late November, poor and erratic rain since late September has resulted in drought and impacted crops across southern Ethiopia, southern Somalia, and coastal Kenya.

  4. Locust outbreak has subsided in northeastern Sudan. However, small scale breeding could increase locust numbers during December, according to the Food and Agriculture Organization.

Central Asia Weather Hazards

A heavy snow hazard is posted for the higher elevations of Afghanistan and Tajikistan where precipitation amounts are forecast to exceed 25 mm, liquid equivalent.

Below-normal temperatures (negative anomalies of 1 to 6 degrees C) persisted across southeast Kazakhstan, Kyrgyzstan, and Tajikistan from November 27 to December 3. Temperatures averaged near to above normal across the remainder of Central Asia. Extreme minimum temperatures were at or below -25 degrees C across parts of northern and eastern Kazakhstan. Minimum temperatures fell below -5 degrees C as far south as Turkmenistan. The GFS model indicates that minimum temperatures will average at or above normal except for northern Kazakhstan where minimum temperatures are forecast.

Precipitation was limited to northern Kazakhstan during the past week. After a favorable pattern that brought much-needed precipitation to Afghanistan including snowfall, dry weather returned during late November and the beginning of December. During the next week, the GFS model indicates a relatively wet pattern with widespread precipitation throughout Central Asia. A heavy snow hazard is posted for the higher elevations of Afghanistan and Tajikistan.

Central America and the Caribbean Weather Hazards

Inconsistent and poor rain during the past several weeks has resulted in abnormal dryness throughout western and central Guatemala and north-central Honduras. Conditions on the ground may worsen as seasonal rain is coming to a close.
