 Areal Flood Watch  Statement as of 9:45 PM CDT on July 23, 2008


... Flood Watch now in effect through late Thursday night...

The Flood Watch is now in effect for

* a portion of south Texas... including the following area... Webb.

* Through late Thursday night

* Hurricane Dolly made landfall Wednesday afternoon and is now a
Tropical Storm. Dolly was over the Rio Grande Valley Wednesday
evening... and is slowly moving west. As Dolly progresses farther
west and winds weaken... the potential for very heavy rainfall
over Webb County... including the city of Laredo... will increase.
The greatest concern for flooding over Webb County and the
Laredo area will be after midnight tonight through Thursday
night.

If Dolly generally follows its forecast track... rainfall amounts
over Webb County from Wednesday night through Thursday night will
average between 4 and 8 inches... with the highest amounts over
southern potions of Webb County... including the city of Laredo.
Also... rainfall rates of two or more inches per hour can be
expected at times. Isolated amounts of 15 or more inches also
cannot be ruled out.

As a result... life threatening flash flooding will be possible
over flood prone areas and over locations receiving these high
rainfall rates. Residents in Webb County are strongly encouraged
to prepare for this potentially dangerous heavy rainfall event.
If you are in a flood prone area... move to higher ground prior to
the onset of heavy rainfall.

A Flood Watch means there is a potential for flooding based on
current forecasts. Residents should monitor later forecasts and be
prepared if flooding is observed or if a warning is issued.

Be especially cautious at night when it is harder to recognize the
dangers of flash floods. If flash flooding is observed... then act
quickly. Move to higher ground to escape flood waters.

Do not drive your vehicle into areas where water covers the
roadway. The water depth may be too high to allow your car to
cross safely. Turn around and do not drown. Vehicles caught in
rising waters should be abandoned quickly.





 Record Report  Statement as of 04:29 PM CDT on July 23, 2008


... Record daily maximum rainfall set at Corpus Christi...

a record rainfall of 2.62 inches (as of 430 PM cdt) was set at
Corpus Christi today. This breaks the old record of 1.47 set in 1919.

Area forecast discussion...updated 
National Weather Service Corpus Christi Texas 
652 PM CDT Wednesday Jul 23 2008 


Aviation... 
not the best time to fly in or out of south Texas for the next 24 
hours...although conditions are expected to improve slightly over 
the eastern portions of the terminal areas on Thursday afternoon. 
Generally have rain showers in the terminals through the period...as 
expect some light rain to be in the area for most of the time 
periods. Generally...forecast periods in the terminals were 
dictated by changes in the wind speeds (tropical storm gusts) and 
directions...but also with some changes in ceilings. Ceilings should 
mainly be MVFR over most locations during the time frame...except 
not initially at klrd and kvct where ceilings will go to MVFR later 
tonight. Have mentioned thunderstorms and rain in the tafs (tempo)...mainly for the 
evening periods (til 04z/05z)...and mainly after sunrise Thursday. 
See individual tafs for details.

Previous discussion... /issued 430 PM CDT Wednesday Jul 23 2008/ 


Short term (tonight through thursday)...Hurricane Dolly made 
landfall near Port Mansfield Texas a couple of hours ago and is 
now progressing west-northwestward at around 8 miles per hour through deep 
south Texas. Rain bands continue to sweep across the forecast area 
bringing heavy rain, gusty winds and weak tornadoes. Local tornado 
threat will gradually diminish throughout the evening hours with 
the loss of daytime heating. Hurricane force winds never did 
materialize across the forecast area today, and now that Dolly is 
onshore, all parties have agreed to downgrade our hurricane 
warnings to tropical storm warnings. Biggest threat remains heavy 
rains. Continued Flood Watch for the southern tier of counties as 
the NAM/WRF and GFS show the degraded center of Dolly making its 
way to Laredo by Thursday afternoon. Thus far, maximum rainfall 
totals near 5 inches along the coastal Bend have not created 
flooding issues, instead have just been beneficial at reducing 
drought conditions. Otherwise, flash flood guidance remains near 3 
to 4 inches for our southwestern counties, which may be reached or 
exceeded over the next 24 hours. Temperatures to remain below normal the 
next 24 hours. 


Long-term (thursday night through wednesday)...remnants of Dolly 
will gradually move northwest along the Rio Grande Thursday night 
with precipitation chances gradually diminishing from east to west after 
midnight. Depending on the speed of the track...Dolly could continue 
to plague residents along the Rio Grande will flooding...especially 
the city of Laredo. Models have been trending a little slower with 
Dolly exiting the region. If this verifies...rainfall/flooding will 
persist across the western brush country longer than anticipated. 
For now will forecast likely probability of precipitation for Webb and LaSalle counties 
Thursday night tapering off to slight chance probability of precipitation by Friday morning. 
Lingering moisture/instability may lead to sea breeze convection 
across the inland sections of the coastal Bend Friday afternoon. A 
gradual drying/warming trend will ensue this weekend into the first 
half of next week as a middle/upper ridge builds into south Texas. 


Marine...wave heights near 22 feet at bouy 42020 and around 17 
feet at bouy 42019. Tropical storm conditions to continue 
overnight then begin subsiding late Thursday.
