Based on CMORPH precipitation estimates that feature precipitation deficits of more than 25 mm during the past 30 days and recent above-normal temperatures, abnormal dryness

Widespread precipitation (rain and high-elevation snow) fell across northern Afghanistan, Tajikistan, and southern parts of Turkmenistan and Uzbekistan for the second

The GFS model indicates that temperatures are likely to remain above normal across Afghanistan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan during the final week

Note: The Hazards outlook map is based on current weather/climate information, short and medium range weather forecasts (up to 1 week), and assesses their potential impact on crop

The frequent precipitation during January and into the beginning of February resulted in above average snow water equivalent amounts across much of northern

Above-normal temperatures continued into early April with the largest anomalies (up to +9 degrees C) observed in northeast Afghanistan.. Maximum temperatures warmed into the middle

Above-normal temperatures persisted through early April with the largest anomalies (+7 or +8 degrees C) observed in southwest Afghanistan and northern Kazakhstan.. Maximum

From April 11 – 20, above-normal mean surface temperatures were observed over the central portions of Central Asia, including much of Turkmenistan, parts of
