A depression in the Bay of Bengal has intensified into a deep depression (01B) and is moving toward Myanmar at a speed of 28 km/h (17.4 mph). The system is expected to become the first named storm of the 2017 North Indian Ocean Cyclone Season, a full month earlier than the first storm of the past season. Landfall is expected on April 17.
At 09:00 UTC (14:30 IST) on April 15, 2017, the center of this system was located over east-central Bay of Bengal, about 350 km (217.5 miles) west-northwest of Maya Bandar, Andaman and Nicobar Islands and 740 km (460 miles) south-southwest of Kyaukpyu, Myanmar, according to RSMC New Delhi, WMO authority for this part of the world.
The center said it expects the system to intensify further into a cyclonic storm by 18:00 UTC (23:30 IST) today. When it does, it will be named Cyclone "Maarutha."

Animated multispectral satellite imagery depicts a rapidly consolidating system with formative banding wrapping into the low level circulation center. Environmental analysis shows favorable conditions with an excellent poleward outflow channel feeding into the midlatitude trough and very warm sea surface temperatures.
