Tropical Storm Mahasen (01B) in Indian Ocean14.3N 87.1E
An area of convection in the Indian Ocean strengthened into Tropical Storm Mahasen (01B) on May 11th.
Multispectral satellite imagery suggested that there was a large area of multiple rainbands leading into a low-level circulation center (LLCC), obscured by deep central convection. Also, low vertical wind shear (VWS) made the weather conditions favorable for tropical cyclogenesis. On 12 May, the IMD reported that Mahasen was weakening as satellite imageries showed the disorganization of the cloud system around the storm.
