On November 22, 2020, Cyclone Gati grew to become the strongest storm to hit Somalia since satellite tv for pc data started 5 many years in the past. Gati made landfall with most sustained winds of 170 kilometers (105 miles) per hour, a class 2 storm on the Saffir-Simpson scale. The storm introduced greater than a yr’s price of rain to the area in two days. Native authorities report at the very least eight individuals had been killed and 1000’s have been displaced.
The natural-color picture above reveals Gati earlier than making landfall over Ras Hafun (the easternmost level in Africa) on November 22. The picture was acquired by the Seen Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite tv for pc.
In 12 hours, Gati’s winds intensified from 65 kilometers (40 miles) to 185 kilometers (115 miles) per hour—the most important 12-hour enhance for any tropical storm ever recorded within the Indian Ocean. The storm quickly intensified as a result of its small dimension, heat Indian Ocean waters, and low wind shear. Though the storm barely weakened earlier than landfall, Gati introduced distinctive quantities of rain to northern Somalia.
The map above reveals rainfall accumulation from November 21-23, 2020. These information are remotely-sensed estimates that come from the Built-in Multi-Satellite tv for pc Retrievals for GPM (IMERG), a product of the World Precipitation Measurement (GPM) mission. Native rainfall quantities might be considerably increased when measured from the bottom.
A lot of northern Somalia, which usually receives about 10 centimeters (4 inches) of rain in a complete yr, acquired at the very least that a lot in two days. Town of Bosaso reported 12.eight centimeters (5 inches) in 24 hours. Heavy rains and robust winds prompted flash floods alongside coastal and inland areas and destroyed buildings. Villages within the Iskushuban district, which incorporates Ras Hafun, had been hit hardest. Gati has since weakened and moved into the Gulf of Aden.
