January 21, 2020 - Flooding in Iran

A storm system hit much of the Middle East from January 9 – 13, 2020, bringing torrential rains, flash floods, heavy snow, and avalanches across a wide area. Snow hit the high mountain regions, claiming at least 130 lives in Pakistan and Afghanistan. Conditions were wetter in the lower-lying areas, with rains drenching an expanse from Saudi Arabia, Qatar, the United Arab Emirates, into northern Oman and southern Iran.

In southern Iran, heavy rain started on January 9, 2020 led to flash floods across the Hormozgan, Kerman, and Sistan-Baluchestan provinces. The floods have destroyed thousands of houses, displaced hundreds of people, and caused at least three fatalities. According to a news report, more than 100 millimeters (4 inches) of rain fell in three days in Sistan-Baluchestan—the amount that typically falls during a full year in that region.

On January 16, the Moderate Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Terra satellite acquired a false-color image showing the extent of flooding in southern Iran. This band combination (7,2,1) uses visible and near-infrared light to highlight vegetation and water. Vegetation appears bright green and water electric blue. Deeper water takes on a deeper hue of blue, darkening to nearly black in oceans. Open land and sand appears tan.
