Dry-Season Floods Drench Northern Colombia

NASA Science
A false-color satellite image captured on February 9, 2026, shows extensive flooding along the Sinu River near Lorica. Dark floodwaters are visible against the green landscape on both sides of the river but especially to its east.

February is one of the driest months of the year in northern Colombia’s Córdoba department, a major farming and cattle region. It’s the time of year when farmers normally prepare fields for planting and ranchers move livestock to graze in drying floodplains. In 2026, however, unusually heavy rains in early February upended seasonal rhythms and submerged much of the department under floodwaters.

The OLI (Operational Land Imager) on Landsat 9 captured this false-color image (bands 7-5-4) of flooding along the Sinú River on February 9, 2026 (right). Dark floodwaters cover farmland, pastureland, and several communities, particularly to the west of the river. To the east, water levels at a complex of wetlands are unseasonably high. Lorica, a city of roughly 90,000 people, is visible in the upper part of the image. The OLI image on the left shows the same area on January 23, before floodwaters arrived.

After an already wet January, rainfall intensified in early February when an unusual cold front in the Caribbean pushed south on February 1 and 2, forcing moisture-laden air into northern Colombia and over the Andes. This led to several days of intense downpours in Córdoba, with some areas receiving more than 4 to 7 centimeters (2 to 3 inches) of rain per day, according to one analysis of the event.

NASA’s IMERG (Integrated Multi-satellite Retrievals for Global Precipitation Measurement) estimated rain rates of 1.7 centimeters per hour near Lorica on February 1, the day of the heaviest rains. In the following weeks, storms continued to drench the region. On February 25, imagery from NASA’s Terra satellite indicated that flooding remained widespread.

The floods have been far-reaching and destructive. More than 80 percent of Córdoba flooded, according to the UN Office for the Coordination of Humanitarian Affairs. Preliminary estimates cited by news and government sources suggest that thousands of homes were destroyed, more than 11,000 families displaced, and more than 150,000 hectares of farmland inundated.
