First disturbance around Mauritius

First disturbance of 2018/2019 season in South West Indian Ocean

Visible satellite imagery (17 Sept. at 14h05 Mauritius Local Time) shows a few cloud swirls pivoting around a mean centre with only a small amount of strongest thunderstorms displaced east of the centre.

At 3am on 17 Sept., the disturbance (01S) was located near 12.3°S and 63.6°E or 950km northeast of Port Louis, Mauritius. It was moving to the west and had maximum sustained winds of 55 km/h. However, the winds were weakening and the system is forecast to dissipate soon.

It is likely to turn into a cluster and continue to move in a general westerly direction with the trade winds. (NASA/NRL)
