1154 AM CDT Wed Sep 5 2018

...MINOR TIDAL OVERFLOW AND INCREASED SWELLS WILL RESULT IN
COASTAL HAZARDS THROUGH THURSDAY MORNING...

.Increased swells from Tropical Storm Gordon are continuing to
move toward the Western Gulf of Mexico. Tide levels are already 
running around 1 foot above predicted levels, and the increased 
swells of around 3 feet with periods around 10 seconds will result
in a high risk of rip currents through tonight and minor tidal 
overflow and coastal flooding overnight tonight and into Thursday 
morning, with coastal flooding worst around high tide overnight 
tonight. Conditions should improve by Thursday afternoon as swells
diminish and tide levels ebb.

...HIGH RIP CURRENT RISK IN EFFECT THROUGH LATE TONIGHT...
...COASTAL FLOOD ADVISORY IN EFFECT FROM 10 PM THIS EVENING TO
NOON CDT THURSDAY...

The National Weather Service in Corpus Christi has issued a
Coastal Flood Advisory, which is in effect from 10 PM this
evening to noon CDT Thursday. A High Rip Current Risk has also
been issued. This High Rip Current Risk is in effect through late
tonight. 

* COASTAL FLOODING...Water levels expected to be around 2 feet
  mean sea level in many areas, especially a few hours on either
  side of high tide. High tide at Bob Hall Pier is at 310 AM CDT
  Thursday, with high tide at Port Aransas at 315 AM CDT Thursday.
  High tide at Matagorda Bay is at 623 AM CDT Thursday. 

* TIMING...through tonight for rip currents and from 10 PM through
  Noon for coastal flooding, especially a few hours before and
  after high tide. 

* IMPACTS...Driving conditions may be impacted. Items along the
  beach may need to be removed due to the incoming wave runup.
  Some beach access roads may become impacted due to water runup
  and may become impassible. Strong rip currents are expected 
  along gulf-facing beaches. These rip currents can be life-
  threatening to anyone entering the surf, especially near piers 
  and jetties. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Coastal Flood Advisory indicates that onshore winds and tides
will combine to generate flooding of low areas along the shore.

Swim near a lifeguard. 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.
