DISCUSSION
-----------------------------------
There has been little change in Beta's overall convective structure 
and intensity, with thunderstorm activity pulsing near the center 
while the outer rain bands have changed little and keep rotating 
onshore the central and upper Texas coastal areas. Dry air 
intrusions into the inner-core region have continued to prevent 
Beta from strengthening by eroding the central dense overcast 
(CDO). The initial intensity of 45 kt is based on data from an Air 
Force Reserve reconnaissance aircraft showing peak SFMR surface 
winds of 40-45 kt and maximum flight-level winds of 50 kt so far, 
along with a dropsonde-measured central pressure of 996-997 mb.West-southwesterly vertical wind shear of 15-20 kt is not only 
expected to keep Beta's track close to the coastline, but it will 
also affect the cyclone's intensity along with land interaction. 
The closer the cyclone stays near the Gulf of Mexico, the more 
likely that bands of convection containing tropical-storm-force 
winds will continue to roll onshore the Texas coast through 36-48 
hours.
