Tropical Storm Mahasen (01B), located approximately 246 nm southward of Kolkata, India, has tracked north-northeastward at 12 knots over the past six hours. Maximum significant wave height is 12 feet.
Animated multispectral satellite imagery indicates the low level circulation center (LLCC) remains under an area of deep convection, but is difficult to identify as the organization of the convection remains poorly defined. A series of scatterometry passes support 35 to 40 knot winds near the center of the LLCC. The current intensity has been maintained at 45 knots based on Dvorak estimates and the persistent convection over the LLCC.
