========================================

At 9:00 AM UTC, Cyclonic Storm Murjan moved westward and now lays near 10.0N 52.5E or 2200 km west southwest of Amini Divi, India (Lakshadweep) 330 km south southwest of Socotra Island, Yemen and 250 km east of Scusciuban, Somalia. The cyclone is likely to move west southwestward and cross Somalia coast near 9.5 at around 21:00 PM UTC, today (October 25th).

According to satellite imagery, the Dvorak intensity of Murjan is T2.5. the lowest cloud top temperature due to convection is around -70C. Associated moderate to intense convection is seen over the Arabian Sea between 7.0N to 14.0N and to the west of 54.5E and adjoining Somalia. The maximum intense convection lies to the southwest sector.

3 minute sustained winds near the center of Murjan is 35 knots gusting up to 45 knots. The central pressure of the system is 1000 hPa. The state of the sea around the center of the cyclone is high.

At 8:00 AM UTC, Socotra Island reported a 1008 hPa mean sea level pressure and winds of 25 knots.

The Madden Julian Oscillation index currently lies over phase 2 with amplitude >1. As per statistical and numerical weather prediction model predictions, it is expected to continue to be in phase 2 during next 3 days. The sea surface temperature is about 26-28C. Over southwest and adjoining west central Arabian Sea. The ocean thermal energy is 50-80 kj/cm2 around the system centre. It is less than 50 kj/cm2 over somalia coast and adjoining seas. The upper tropospheric ridge lies along 15.0N and hence lies to the north of the system center. The low level convergence as well as lower level relative vorticity show no significant change during past six hrs. However, upper level divergence shows increase during the same period. The vertical wind shear between 200 and 850 hpa levels is moderate (05-15 knots) around system center and there has been no significant change during past 24 hrs.
