December 17, 2022 - Tropical Cyclone 07A
Tweet
On December 16, 2022, the Moderate Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Terra satellite acquired a true-color image of a short-lived cyclone losing the struggle to strengthen over the Arabian Sea off the western coast of India.
Tropical Cyclone 07A formed from the remnants of Tropical Cyclone Mandous, which made landfall on December 9 near the town of Mamallapuram in the state of Tamil Nadu, on the southeast coast of India. Mandous carried maximum sustained winds of 50 mph (80.5 km/h) shortly prior to landfall and quickly weakened to a depression after moving over the coast. The depression continued moving westward and once it moved across the western Indian coast on December 12, the rag-tag remnants began to coalesce, becoming a tropical depression with maximum sustained winds of 15 mph (24 km/h). By December 14, 07A achieved Tropical Cyclone status with maximum sustained winds of 50 mph (80.5 km/h).
On the evening of December 16, the Joint Typhoon Warning Center issued its last advisory on Tropical Cyclone 07A. At that time, the system was located about 602 miles (969 km) southeast of Masirah Island with maximum sustained winds of 40 mph (64 km/h). The system was moving westward and facing strong vertical windshear. According to the advisory, the unfavorable conditions expected going forward mean that it is “not long for this world”. The advisory expected that 07A would continue to weaken, and would dissipate slowly over open ocean.
