Westerly wind shear and dry air keeping Beta from intensifying.

The storm has weakened over night, and now has sustained winds of 50 mph. It is moving slowly to the west, and will likely make landfall along, or south of Matagorda Bay later today or early Tuesday. The storm is continuing to battle moderate wind shear and the entrainment of dry air into its circulation. These factors are unlikely to change much as the storm nears the coast, and the National Hurricane Center anticipates it will remain at its current intensity until landfall.

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. Given that the models over the past 24 hours have been
trending toward a track closer to the coast, the NHC official
intensity remains unchanged from the previous advisory, and lies a
little above all of the available guidance through 48 hours.

The center of Beta is 20 miles south. Not much in the way of wind. Overnight, 4.5 inches of rain and still raining.

The initial motion estimate is now 045/02 kt. Steering currents
around Beta remain weak. However, water vapor imagery indicates that
a broad mid- to upper-level trough over western Texas is moving
slowly eastward, and that feature should gradually force Beta
east-northeastward later today and tonight, followed by a faster
motion toward the northeast on Wednesday and Thursday across
Louisiana and Mississippi before dissipating in about 4 days.
