OMISSION OF CERTAIN NAVIGATIONAL AIDS AND WRECKS Certain lights, wrecks, buoys and beacons have been omitted from this chart; for detail of these, the larger scale charts and List of Lights should be consulted. CURRENTS The currents are monsoonal in character. During the SW monsoon there is a branching, towards the NE, from the northern flank of the general SEly flow across the entrance to Gulf of Mannar. This continues as a NEly flow through the narrow channels connecting the northern part of the Gulf with Palk Strait in December and January (NE-monsoon) the flow is southward through these channels which implies a mainly SWly flow across the Gulf. For further information see also Sailing Directions, Admiralty Currents Atlases etc. The currents may on occasions, be markedly different from these average conditions and rates upto 2 kn may occur with prolonged strong winds.
