Tropical Cyclone Emang picks up speed

Tropical Cyclone Emang picks up speed

According to latest report by Joint Typhoon Warning Center (JTWC), Tropical Cyclone Emang was located approximately 500 nm east- southeast of Diego Garcia, and was moving at speed of 5 knots. Animated infrared (IR) satellite imagery depicts a partially exposed low-level circulation center (LLCC) with a recent flare of convection over the northwest quadrant of the LLCC.

Upper level analysis reveals TC Emang is located within a marginal environment with poor outflow and moderate (10-20 knots) vertical wind shear. The system remains within a weak steering environment but has picked up speed over the last hours tracking westward under the influence of a building subtropical ridge to the south.

Emang is expected to move  slowly  southwestward along the northern periphery of this building subtropical ridge.  Emang is expected to intensify slowly to a peak intensity of 65 knots by the next few days under the moderately favorable environmental conditions.
