issued. This High Rip Current Risk is in effect from 7 AM EST
this morning through Saturday evening. The Coastal Flood Watch is

from Thursday evening through Friday afternoon. Residents living 
near those areas should pay close attention to the local weather
 and seek higher ground in case of flooding.

* COASTAL FLOOD TIMING...Coastal flooding can be expected from 
  Thursday evening through Friday afternoon. 

* COASTAL FLOOD IMPACTS...There is the potential for some roads 
  to become impassible and water to enter structures along the 
  shore, particularly with added wave action. In addition, boat 
  ramps, beach access roads, and decks will likely be affected. 
  The dangers of flooding are especially hard to recognize at 
  night. If you encounter flood waters, turn around dont drown! 

* HIGH SURF...Large breaking waves around 5 feet this afternoon
  increasing to 6 to 10 feet by Friday and continuing through the
  Saturday. 

* HIGH SURF TIMING...This afternoon through Saturday evening. 
 
* HIGH SURF IMPACTS...High surf will affect beaches in the 
  advisory area...producing localized beach erosion and dangerous 
  swimming conditions.

* RIP CURRENT TIMING...Increasing wave action will keep rip 
  currents likely along area beaches through late Saturday 
  evening. 

* RIP CURRENT IMPACTS...Life threatening Rip Currents are likely
  through Saturday. Always swim near a lifeguard, and never swim 
  alone!
  
PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Coastal Flood Warning means that flooding is occurring or
imminent. Coastal residents in the warned area should be alert
for rising water...and take appropriate action to protect life
and property.

A High Surf Advisory means that high surf will affect beaches in
the advisory area...producing localized beach erosion and
dangerous swimming conditions.

Rip currents are powerful channels of water flowing quickly away
from shore...which occur most often at low spots or breaks in the
sandbar and in the vicinity of structures such as groins...
jetties and piers. For maximum safety...swim near a lifeguard.
Pay attention to flags and signs.

If you become caught in a rip current...yell for help. Remain
calm...do not exhaust yourself and stay afloat while waiting for
help. If you have to swim out of a rip current...swim parallel to
shore and back toward the beach when possible. Do not attempt to
swim directly against a rip current as you will tire quickly.

EVENING...
...HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL 9 PM EST SATURDAY...
...HIGH RIP CURRENT RISK REMAINS IN EFFECT THROUGH SATURDAY
EVENING...

* COASTAL FLOODING...A strong onshore flow and large breaking wave
  action combined with high tides will cause coastal flooding in 
  low lying areas. Residents living near those areas should pay 
  close attention to the local weather and seek higher ground in 
  case of flooding. 

* COASTAL FLOOD TIMING...Coastal flooding can be expected through
  this evening especially during time of high tide this  
  afternoon.
  
* COASTAL FLOOD IMPACTS...There is the potential for some roads 
  to become impassible and water to enter structures along the 
  shore, particularly with added wave action. In addition, boat 
  ramps, beach access roads, and decks will likely be affected. 
  The dangers of flooding are especially hard to recognize at 
  night. If you encounter flood waters, turn around dont drown! 

* HIGH SURF...Large breaking waves around 7 to 10 feet.

* HIGH SURF TIMING...Through Saturday evening.

* HIGH SURF IMPACTS...High surf will affect beaches in the 
  advisory area...producing localized beach erosion and 
  dangerous swimming conditions. 

* RIP CURRENT TIMING...Increasing wave action will keep rip 
  currents likely along area beaches through Saturday evening. 

* RIP CURRENT IMPACTS...Life threatening Rip Currents are likely 
  through Saturday. Always swim near a lifeguard, and never swim 
  alone! 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Coastal Flood Warning means that flooding is occurring or
imminent. Coastal residents in the warned area should be alert
for rising water...and take appropriate action to protect life
and property.

A High Surf Advisory means that high surf will affect beaches in
the advisory area...producing localized beach erosion and
dangerous swimming conditions.

Rip currents are powerful channels of water flowing quickly away
from shore...which occur most often at low spots or breaks in the
sandbar and in the vicinity of structures such as groins...
jetties and piers. For maximum safety...swim near a lifeguard.
Pay attention to flags and signs.

If you become caught in a rip current...yell for help. Remain
calm...do not exhaust yourself and stay afloat while waiting for
help. If you have to swim out of a rip current...swim parallel to
shore and back toward the beach when possible. Do not attempt to
swim directly against a rip current as you will tire quickly.
