1. Significant flash and urban flooding is occurring and willcontinue for the middle and upper Texas coast today. The slow motionof Beta will continue to produce a long duration rainfall event fromthe middle Texas coast to southern Louisiana. Flash, urban, andminor river flooding is likely. Periods of rainfall will continueinto the ArkLaTex region and spread east into the Lower MississippiValley and portions of the Southeast through the end of the week.Flash, urban, and isolated minor river flooding is possible.

2. Storm surge flooding will continue throughout the morning, aroundthe times of high tide along portions of the Texas coast within thestorm surge warning areas. Residents in these areas should continueto follow advice of local officials.

3. Tropical-storm-force winds will continue near portions of theTexas coast within the warning area today.

CHANGES WITH THIS ADVISORY:

None.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Storm Surge Warning is in effect for...
- Sargent Texas to Sabine Pass including Galveston Bay

A Tropical Storm Warning is in effect for...
- Port Aransas Texas to Sabine Pass

A Storm Surge Warning means there is a danger of lifethreatening inundation from rising water moving inland from the coastline in the indicated locations. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a lifethreatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials.

A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area.

For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office.

Key messages for Beta can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC.

STORM SURGE: The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide...

Sargent, TX to Sabine Pass including Galveston Bay...24 ft Sabine Pass to Ocean Springs, MS including Sabine Lake, Calcasieu Lake, Vermilion Bay, Lake Borgne, Lake Pontchartrain, and Lake Maurepas...13 ft Baffin Bay, TX to Sargent, TX including Copano Bay, Aransas Bay, San Antonio Bay, Matagorda Bay, Corpus Christi Bay and Baffin Bay... 13 ft Mouth of the Rio Grande to Baffin Bay, TX...12 ft

The deepest water will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by large and dangerous waves. Surgerelated flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office.

WIND: Tropical storm conditions are expected to continue within portions of the tropical storm warning area today.

RAINFALL: For the middle and upper Texas coast, additional rainfall of 6 to 12 inches with isolated storm totals up to 20 inches is expected. Significant flash and urban flooding is occurring and will continue today. Minor river flooding is likely.

Rainfall totals of 3 to 5 inches are expected northward into the ArkLaTex region and east into the Lower Mississippi Valley through the end of the week. Flash and urban flooding is possible, as well as isolated minor river flooding.

TORNADOES: A tornado or two could occur today near the upper Texas and southwestern Louisiana coasts.

SURF: Swells generated by a combination of Beta and a cold front over the northern Gulf of Mexico will continue along the coasts of Louisiana and Texas during the next couple of days. These swells are likely to cause lifethreatening surf and rip current conditions. Please consult products from your local weather office.

At 700 AM CDT (1200 UTC), the center of Tropical Storm Beta was located by surface observations and NOAA Doppler radars near latitude 28.8 North, longitude 96.8 West. Beta is moving toward the northwest near 3 mph (6 km/h). Beta is expected to stall inland over Texas today but will then begin to move slowly toward the eastnortheast tonight. An eastnortheast to northeast motion with increasing forward speed is expected Wednesday through Friday. On the forecast track, the center of Beta will move inland over southeastern Texas through Wednesday and then over Louisiana and Mississippi Wednesday night through Friday.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Beta is likely to begin weakening later today.

Tropicalstormforce winds extend outward up to 105 miles (165 km) from the center. A sustained wind of 39 mph (63 km/h) and a gust to 47 mph (76 km/h) was recently reported at Victoria, Texas.

The estimated minimum central pressure is 999 mb (29.50 inches).

Beta's center has continued to move farther inland since makinglandfall on the southern end of the Matagorda Peninsula around 10PM CDT last evening. There have not been any surface observationsof sustained tropical-storm-force winds, and an earlier ASCAT passindicated that winds over the water had decreased to near 35 kt.That is Beta's estimated intensity at the moment, with theassumption that those winds are still occurring somewhere overwater or within the deep convection near the center.

Beta has been moving northwestward, or 315/3 kt. Steering currentsaround the storm are now collapsing, and Beta is expected tomeander during the next 12-24 hours. By this time tomorrow,however, a mid-level trough over west Texas is forecast to beginmoving eastward and should scoop Beta up, causing the storm to movetoward the east-northeast near or just inland of the upper Texascoast through 36 hours. After that time, Beta is expected to turnnortheastward, moving farther inland across Louisiana andMississippi before dissipating in about 4 days. Because Beta hasmoved a little farther inland than expected, much of the modeltrackers have shifted northward, and now only the UKMET and itsensemble mean show Beta's center re-emerging over the extremenorthwestern Gulf of Mexico. The new NHC track forecast has beenadjusted northward accordingly and generally lies between the HCCAaid and the TVCN multi-model consensus.

Now that Beta's center may not move back out over the Gulf, theintensity guidance indicates that the cyclone will gradually weakenduring the next few days. However, since a part of the circulationwill remain over water and the system could still produce deepconvection, the NHC forecast shows Beta maintaining tropical stormstatus for another 12 hours or so (a scenario which is above allof the guidance). Beta should weaken to a tropical depression inabout 24 hours, and it is expected to become a remnant low in 2-3days when vertical shear is expected to be well over 30 kt.
