Tropical Cyclone 02B (Asani), is located approximately 532 NM south-southwest of Kolkata, India

According to the JTWC Warning number 8, sustained winds were 55 knots with gusts to near 70 knots.

Satellite imagery depicts intense bursts of deep convection, vertical hot towers, flaring within an irregular central dense overcast (cdo) with very cold cloud top temperatures.

A microwave image reveals tightly-curved banding wrapping into the eastern quadrant of the low-level circulation center (llcc) with intense deep convection along the southeastern quadrant.

Despite increasing easterly vertical wind shear, poleward and westward outflow remain vigorous allowing the system to maintain a compact cdo and vertical hot towers.

Due to the compact core and robust outflow through 24 hours, TC 0B will intensify slightly to 75 knots at 12 to 24 hours. After 24 hours, the system will steadily weaken as easterly vertical wind shear increases to 30-35 knots and outflow decreases.

After 48 hours, increasing westerlies over northeast India will gradually erode the ridge allowing the system to turn poleward.

After 72 hours, TC 02B will track northeastward and will interact with the mid-latitude trough expected to deepen over the northern Bay of Bengal with significant weakening down to 35 knots by 120 hours.
