Watches & Warnings

High Surf Advisory, Coastal Flood Statement
Issued: 3:43 PM EDT Jun. 24, 2017 – National Weather Service

... High surf advisory remains in effect until 8 PM EDT this evening...

... Splashover on the most vulnerable shoreline roads between 10 PM and 1 am
tonight...

* location... Nantucket

* timing... high surf this afternoon and evening. Tidal impacts around the time
of high tide near midnight.

* Surf and rip current risk... seas up to 7 feet just offshore will result in
high surf and an increased risk for dangerous rip currents.

* Tidal departure... less than one half foot.

* Coastal flood impacts... very minor inundation of the typical most vulnerable
shoreline roads.

Precautionary/preparedness actions...

A rip current... sometimes mistakenly called an undertow... is a strong but
narrow current of water flowing from the beach to the surf zone. It can rapidly
carry a swimmer into deeper water... and exhaust an individual trying to swim
against it.

If you are a poor swimmer and are caught in a rip current... swim parallel to
the beach until out of its pull... then swim back to shore. Another means of
escape for good swimmers is to ride the current out until it dissipates... then
swim back to shore outside of the rip current.

Do not attempt to swim directly into the rip current... it can exhaust and drown
even the strongest swimmer.

Heed the advice of the beach patrol and swim only at guarded beaches. Be
especially cautious near piers and jetties... where rip currents can be
enhanced.

In addition... viewers of large surf should stay in safe areas well away from
possible splashover. Individual waves may be more than twice the average wave
height... which can sweep a person into the water from what may seem to be a
safe viewing area. Falling into turbulent and sometimes Rocky Waters can result
in injury that reduces the chance of survival.
