As a result, tropical storm watches have been upgraded to tropical storm warnings north of Port Aransas.
Beta is the Atlantic's 23rd storm for 2020 so far, the second most active season in records going back to 1851.
As it approaches the eastern Atlantic coastline of Nova Scotia, the storm will undergo post-tropical transition.
There's only been one other year - 2005 - that Greek names have been needed, where officials had to use a total of six Greek letters.
A hurricane hunter aircraft has found that Beta remains a strong tropical storm with maximum sustained winds near 60 miles per hour, according to a bulletin issued by the National Weather Service office in Corpus Christi.
The 2020 summer has brought a string of natural disasters to the US, from hurricanes and tropical storms to a derecho that left wreckage from Iowa to IN, to fires IN the West that have killed dozens of people and scorched millions of acres.
The only time they had done this before was in the deadly 2005 hurricane season, during which Hurricane Katrina devastated New Orleans. "Beta is expected to move slowly northwest toward the mid Texas coast through Monday night and is forecast to become a hurricane before landfall".
Tropical Storm Beta is located about 280 miles east-southeast of the mouth of the Rio Grande and is moving to the north-northeast at 9 mph (15 km/h). Tropical Storm Wilfred is the last named storm of the 2020 season using the English alphabet.
Elsewhere in the Atlantic, Hurricane Teddy, a powerful Category 4 storm, is continuing to move toward Bermuda.
The center of Teddy is forecast to pass to the east of Bermuda, but a tropical storm warning is in effect for the island.

Hurricane-force winds begin at 74 miles per hour. "Environmental conditions are expected to be conducive for additional development during the next day or two and a tropical depression or tropical storm could form before the end of the week", forecasters wrote. If it turns into a tropical storm and Wilfred already exists, it would be called Tropical Storm Alpha.
In the statement issued early Saturday morning, Environment Canada said Teddy is now a category three system over the Tropical Atlantic well southeast of Bermuda.
