Beryl formed from a tropical wave that moved westward from Africa on June 23rd accompanied by a disorganized area of showers and thunderstorms. The wave moved westward across the eastern tropical Atlantic for the next few days with little development. The associated thunderstorm activity showed signs of organization on the 28th, and by early on the 28th a better-defined circulation had formed with increasingly organized convection. Continued development led to the formation of a tropical depression late on the morning of the 28th about 1200 miles east of Barbados. The depression moved just north of west within an area of unusually favorable deep-layer easterly flow/low vertical wind shear. This favorable environment fostered continued development, with tropical storm status achieved that night. Beryl rapidly intensified and reached hurricane strength during the evening of the 29th. Rapid strengthening continued with Beryl becoming a major hurricane on the 30th, about 260 miles east-southeast of Barbados. At that point, Beryl began an eyewall replacement cycle (ERC), which caused weakening that evening. The hurricane turned west-northwestward with a forward motion of 18–20 kt. Beryl emerged from the ERC with an eye of about 20 miles in diameter, and rapid strengthening resumed immediately as this new eye contracted. The hurricane moved across Carriacou around midday on July 1st. Strengthening continued over the southeastern Caribbean Sea. Later on the 2nd, Beryl entered an area of westerly vertical wind shear that covered the central and western Caribbean Sea, which led to two days of gradual weakening. While this weakening occurred, the center moved through the central Caribbean Sea south of Hispaniola and then passed barely south of the southern coast of Jamaica on the 3rd, after losing major hurricane intensity.
Continuing west-northwestward, the center passed south of the Cayman Islands early on the 4th. A few hours later, Beryl reintensified some despite the ongoing shear, with the hurricane becoming major once more on the evening of the 4th. Beryl rapidly weakened but remained a hurricane by the time the center made landfall on the Yucatan Peninsula of Mexico just northeast of Tulum on the morning of the 5th. Beryl further weakened over the Yucatan Peninsula, with thunderstorm activity becoming sparse within its circulation, as the combination of vertical wind shear and land interaction took their toll. The cyclone weakened to a tropical storm with poorly organized convection as it emerged over the southwest Gulf of Mexico late on the 5th, fairly close to an upper level low. Continued shear and dry air entrainment allowed only gradual redevelopment as Beryl moved northwestward across the southwestern and western Gulf of Mexico on the 6th, as new thunderstorm activity led to a general moistening of its environment. Beryl turned north-northwestward on the 7th as it moved into a break in the subtropical ridge caused by a large mid-latitude trough over the central United States. A combination of decreasing shear and the moistening airmass allowed re-intensification to begin in earnest. The cyclone regained hurricane strength around on the night of the 7th as it approached the Texas coast and continued to strengthen as it made landfall near Matagorda, Texas.
The center then moved northward and north-northeast, passing over the western side of the Houston metropolitan area on the morning of the 8th before moving farther inland into eastern and northeast Texas. Beryl weakened to a tropical storm while passing near Houston, and it weakened to a tropical depression over northeastern Texas on the evening of the 8th. The cyclone then merged with a frontal system and became an extratropical low over central Arkansas by the morning of the 9th. As an extratropical low, Beryl moved northeastward through the mid-Mississippi and Ohio Valleys, reaching the central Great Lakes by late on the 10th. While no widespread strong winds accompanied the low, the system produced locally heavy rains in a swath from Arkansas to New Brunswick, accompanied by many tornadoes. The extratropical low weakened on the 11th, and it was absorbed by its triple point low to the east later that day.
