Tracking westward, the wave failed to organize substantially until entering the Bay of Campeche, at which time it developed into a tropical storm.

It made landfall in the Mexican state of Tamaulipas as a weak tropical storm with winds of 50 mph (80 km/h) on August 15, 2000 and dissipated over mountainous terrain shortly thereafter.

It tracked westward across the tropical waters of the Atlantic Ocean and broke into two distinct parts, the northern portion eventually became Hurricane Alberto.

The wave was upgraded to Tropical Depression Five later that day, based on satellite intensity estimates and an observation from an Air Force Reserve reconnaissance aircraft.

[3] It was upgraded to Tropical Storm Beryl late on August 14 with surface winds of 50 mph (80 km/h), based on reconnaissance aircraft observation.

[1] Six hours later, the storm accelerated to near 9 mph (14 km/h), meaning that landfall would happen sooner than expected, preventing the time for Beryl to strengthen to a hurricane.

Tropical Storm Beryl continued to track to the northwest toward the Rio Grande Valley area in the southern portion of the U.S. state of Texas.

[1] The Brownsville radar showed that the circulation center of the storm became elongated parallel to the mountain ranges of northeastern Mexico, so the system was no longer declared a tropical depression late on August 15,[5] while located near Monterrey.

[6] Thousands of residents in coastal areas of southern Texas and northern Mexico were asked to pay attention to the hurricane warnings and to move towards higher ground.

The National Weather Service warned the cities of Cameron and Kenedy, and Willacy County in southern Texas that severe flooding is the deadliest threat associated with the storm.

[10] Beryl made landfall in a sparsely populated region of northeast Mexico, so no official reports of tropical storm force winds were recorded.
