Full details
* WHAT...Dangerous rip currents.

* WHERE...Kings (Brooklyn), Southwest Suffolk, Southeast
Suffolk, Southern Queens and Southern Nassau Counties.

* WHEN...Through this evening.

* IMPACTS...Life-threatening rip currents are likely for all
people entering the surf zone. Anyone visiting the beaches
should stay out of the surf. Rip currents can sweep even the
best swimmers away from shore into deeper water.

If you enter the surf zone, always have a flotation device with
you and swim near a lifeguard. If caught in a rip current, relax
and float, and do not swim against the current. If able, swim in
a direction following the shoreline. If unable to escape, face
the shore and yell or wave for help.
