These are called rip currents
Two kinds of currents that wave action can cause near shore are "Longshore Current", which is the overall direction and movement of the waves that strike the shore at an angle. The other kind of current is "Rip Currents", which are narrow streams of water that break through sandbars and drain rapidly back to sea.
When wind and waves push water toward the shore, water is often forced sideways by the oncomin waves. The water streams along the shore until it finds its way back to an open sea or lake a riptide can usually narrow and in a trench between sandbars, under piers and sometimes along jetties.

Jet Streams are narrow belts of high speed winds.
The narrow belts of winds that can reach 400 km are called jet streams. They are fast-flowing, narrow air currents found in the upper atmosphere, typically at altitudes of 7-16 km. Jet streams have a significant influence on weather patterns and can impact the movement of storms.
jet streams!! :D
Lakes and rivers
Rip currents are powerful, narrow channels of water that flow away from the shore. They form when waves break over sandbars or other underwater structures, creating a buildup of water that seeks to return to the sea. This water channels through gaps in the sandbars, resulting in a strong current that can pull swimmers away from the shore. Understanding their formation helps beachgoers recognize and avoid dangerous conditions.
Narrow belts of high speed winds in the upper atmosphere are known as jet streams. These fast-flowing air currents can have significant influence on weather patterns and are commonly found near boundaries between warm and cold air masses. Jet streams are strongest in the wintertime when temperature contrasts are typically the greatest.
