The National Hurricane Center says little change in strength is likely before Tropical Storm Bill makes landfall in Texas on Tuesday morning.
The storm's maximum sustained winds remain near 50 mph (85 kph) and Bill is expected to weaken some as its center moves inland.
The tropical storm is centered about 55 miles (90 kilometers) southeast of Port O'Connor, Texas, and is moving northwest near 13 mph (20 kph).
A tropical storm warning is in effect for the coast of Texas from Baffin Bay to High Island.

The forecast follows historic rains and floods last month. Both Texas and Oklahoma had their wettest month of any month on record during May. New heavy rainfall is likely to result in flooding.
