MAXIMUM SUSTAINED WINDS...50MPH...85KM/H MINIMUM CENTRAL PRESSURE...996MB WATCHES AND WARNINGS ----------------------------------- A Tropical Storm Warning is in effect for... * Port Aransas Texas to Morgan City Louisiana A Tropical Storm Watch is in effect for... * Baffin Bay to Port Aransas Texas
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.
