10 AM Update: Tropical Storm Bertha is forecast to approach the Texas coast as a tropical depression by early Friday. Wind shear, dry air and land interaction could limit the storms organization as it approaches Texas late week. No impacts are expected for South Central Texas through Thursday night. Friday into the weekend, moisture from Bertha or its remnants could bring a low chance (20-30%) of showers, favoring the Coastal Plains. Please follow us and other trusted sources including hurricanes.gov through the week.
