...Minor Coastal Flooding Possible through Wednesday Morning...

Long period swells generated by distant, but large and powerful
Hurricane Lorenzo over the central Atlantic will build into the
central Florida Atlantic surf zone early this week. These swells
will combine with increasing onshore winds and chop, as well as
the King Tides, or highest astronomical tides of the year, to
increase the potential for minor coastal flooding around the
times of high tides for several days. High tides will average
around one foot above normal through mid day Wednesday.

...HIGH RIP CURRENT RISK IN EFFECT FROM 8 AM EDT THIS MORNING
THROUGH THIS EVENING...

......MINOR COASTAL FLOODING POSSIBLE FOR SEVERAL HIGH TIDE CYCLES
THROUGH WEDNESDAY MORNING...

* COASTAL FLOODING...Wave runup from a combination of large 
  swells from distant Hurricane Lorenzo and high astronomical 
  tides may cause water to breach eroded dunes in some 
  locations. Some lowlands along the intracoastal waterways may 
  also experience minor flooding near the times of high tide. 

* COASTAL FLOODING TIMING...The threat will be highest around  
  high tide through Wednesday morning. 

     This morning between 1030 AM and 1100 AM 
     Tonight between 1045 PM and 1115 PM 
     Wednesday morning between 1115 AM and 1145 AM

* RIP CURRENTS...Ocean conditions will produce strong rip currents
  in the surf zone, posing a threat to all levels of swimmers.
  Entering the surf is not advised. 

* RIP CURRENTS TIMING...While life-threatening rip currents will
  be present all day, the threat will be highest during the hours
  surrounding low tide, which will be from 2 PM to 8 PM this 
  afternoon.

* Impacts...Minor coastal flooding is possible. The swells will 
  also produce a high rip current risk into mid week. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A coastal flood statement is issued when minor coastal flooding
is possible near the coast and along low areas near the
intracoastal waterways, especially around the times of high tide.

A high rip current risk is expected into mid week.

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 jetties and
piers. Heed the advice of lifeguards...beach patrol flags and
signs. If caught in a rip current, relax and float. Don't swim 
against the current. If able, swim in a direction following the 
shoreline. If unable to escape, face the shore and call or wave 
for help.
