caption_attribution_description: English: Track map of Hurricane Allison of the 1995 Atlantic hurricane season. The points show the location of the storm at 6-hour intervals. The colour represents the storm's maximum sustained wind speeds as classified in the Saffir–Simpson scale (see below), and the shape of the data points represent the nature of the storm, according to the legend below.

context_page_description: Hurricane Allison was the first named storm and first hurricane of the 1995 Atlantic hurricane season. It was an early season hurricane that delivered heavy rains and caused minor damage, primarily across Cuba, Florida and Georgia.
  The storm developed on June 2, less than 48 hours after the official start of the hurricane season. It strengthened into a tropical storm early on June 3 and into a hurricane on June 4 in the Gulf of Mexico. It would make landfall in the Big Bend area of Florida on June 5 before tracking northward as an extratropical system. One death was reported in Cuba. Allison's early formation heralded the start of what would eventually become a very active 1995 hurricane season.
context_section_description: The origins of the system can be traced to a tropical wave that moved across the eastern Caribbean in the last week of May. The wave gradually organized itself as it entered the western Caribbean Sea on June 1. The circulation continued to close up on June 2 and that evening it was declared Tropical Depression One while east of Honduras.
  The depression was in an unusually low-shear environment for early June as it began tracking northward, which allowed the system to strengthen into Tropical Storm Allison on the morning of June 3 as it tracked into the Yucatán Channel. Despite the fact that westerly wind shear began to increase, the warm water allowed Allison to gradually strengthen more that afternoon and evening. Late that evening, while between the Yucatán Peninsula and Cuba, Allison developed a circular central dense overcast and became a high-end tropical storm. As the storm emerged into the Gulf of Mexico, the warm waters allowed Allison to strengthen further and it was upgraded to a hurricane on the morning of June 4 while travelling almost due north.
  Allison remained somewhat disorganized, as no eye was visible, even when Reconnaissance flights confirmed that it was at hurricane intensity. The storm maintained itself as a minimal hurricane throughout the day on June 4 before it began to turn to the northeast, in response to southwesterly shear. Late that evening, the storm began to weaken, dropping back to tropical storm intensity as it approached the Florida Big Bend area. The intensity leveled off on June 5 until it made landfall that morning. Allison made its first landfall at about 10:00 am EDT (1400 UTC) near Alligator Point, Florida as a high-end tropical storm with 70 mph (110 km/h) winds. It briefly re-emerged over Apalachee Bay and made another landfall near St. Marks, Florida about one hour later with 65 mph (100 km/h) winds. Operationally, Allison was considered a hurricane until it made landfall, and was considered the earliest hurricane landfall in the United States for some time.
  After making its final Florida landfall, Allison rapidly weakened. Tropical storm force winds continued over the eastern Florida Panhandle until late that afternoon, as the storm moved northward into Georgia. It weakened to a tropical depression on the evening of June 5 over southern Georgia. Early on June 6, Allison began to transition into an extratropical storm as it interacted with a warm front to the northeast while tracking across the Carolinas. The remnant low emerged into the Atlantic Ocean off the coast of Cape Hatteras that evening. It then raced across the western Atlantic, crossing the easternmost part of Nova Scotia on June 8 and Newfoundland on June 9. It continued northward across the Labrador Sea, dissipating on June 11.
