Tropical Storm Beryl (2000)
Tropical Storm Beryl made landfall just south of the United States–Mexico border in mid-August 2000, causing mimimal damage. The second named storm of the 2000 Atlantic hurricane season, Beryl originated from a tropical wave near the African coastline. Tracking westward, the wave failed to organize substantially until entering the Bay of Campeche, at which time it developed into a tropical storm. Beryl rapidly deepened while in the Gulf of Mexico, and it initially was forecast to strengthen to a hurricane under favorable conditions for development. Instead, Beryl remained at moderate tropical storm intensity and failed to intensify any further. It made landfall in the Mexican state of Tamaulipas as a weak tropical storm with winds of 50 mph (85 km/h) on August 15 and dissipated over mountainous terrain shortly thereafter. One death was reported in Mexico due to drowning. Otherwise, no significant damage was reported associated with Beryl, as it affected a sparsely populated area of Mexico.
== Meteorological history ==
A tropical wave emerged from the African coast with a closed circulation on August 3. 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 southern portion continued to track westward into the Caribbean Sea, while producing little or no deep convection. The wave reached Mexico's Yucatán Peninsula on August 12, and only then did deep convection redevelop, mostly due to diurnal heating. The wave emerged over the Bay of Campeche early on August 13 as a large area of low pressure. 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. Six hours after developing, the depression was forecast to strengthen into a hurricane early on August 16 due to the warm waters of the Gulf of Mexico and little wind shear to inhibit development.
The tropical depression traveled to the northwest across the southwest Gulf of Mexico.〔 It strengthened rapidly, and there was evidence of deep convection as it passed over warm waters. It was upgraded to Tropical Storm Beryl late on August 14 with surface winds of 50 mph (85 km/h), based on reconnaissance aircraft observation.〔 Six hours later, the storm accelerated to near 9 mph (15 km/h), meaning that landfall would happen sooner than expected, preventing the time for Beryl to strengthen to a hurricane. However, Beryl failed to undergo significant intensification as was forecast, as it maintained an intensity of 50 mph (85 km/h). The lack of intensification could be due to moderate wind shear and entrainment over the Gulf of Mexico. 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. The storm made landfall early on August 15 along the Mexican coast about 105 mi (165 km) south of Brownsville, Texas, 35 mi (55 km) north La Pesca, Tamaulipas〔 and about 115 mi (185 km) north of Tampico. Beryl was downgraded to a tropical depression about five hours after landfall.〔 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, while located near Monterrey.〔
