The structure of Tropical Storm Beryl did not change a lot on Saturday.  The inner end of a rainband wrapped around the western side of the center of Beryl’s circulation.  Bands of showers and thunderstorms revolved around the center to Tropical Storm Beryl.  Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease slowly.

The size of the circulation around Tropical Storm Beryl also did not change much on Saturday.   Winds to tropical storm force extended out 125 miles (200 km) in the northern half of Beryl’s circulation.  Winds to tropical storm force only extended out 45 miles in the southern half of Tropical Storm Beryl.

Tropical Storm Beryl will move into an environment that will become more favorable for intensification during the next 24 hours . Beryl will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the northern part of an upper level low over the western Gulf of Mexico.  The upper level low will produce southeasterly winds that will blow toward the top of Beryl’s circulation.  The winds in the lower levels of the atmosphere will also blow from the southeast.  Since the winds in the upper and lower levels will blow from the southeast, there will be little vertical wind shear.  Tropical Storm Beryl will intensify during the next 24 hours.  Beryl is likely to strengthen to a hurricane.  Beryl could intensify rapidly if an inner core with an eye and and eyewall develops.  There is a chance Beryl could intensify to a major hurricane before it reaches the coast.

Tropical Storm Beryl will move around the southwestern part of a high pressure system over the southeastern U.S.  The high pressure system will steer Beryl toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Beryl will approach the coast of Texas on Sunday night.

Tropical Storm Beryl is likely to be a hurricane when it reaches the coast of Texas.  Beryl will bring strong winds and heavy rain to parts of eastern Texas.  Up to 10 inches (250 mm) of rain could fall in some locations.  Heavy rain is likely to cause flooding.  Flood Watches were in effect for parts of eastern Texas.  Tropical Storm Beryl could also cause a storm surge of up to 10 feet (3 meters) where the wind pushes water toward the coast.
