Ураган Берта: Траектория и последствия (1996)

Category 3 Atlantic hurricane in 1996

Hurricane Bertha was an intense and early forming major hurricane that affected areas from the Leeward Islands to the United States in July of the 1996 Atlantic hurricane season. The second named storm, first hurricane, and first major hurricane during the season, Bertha originated from a tropical wave that moved off the coast of Africa in early July. Steadily organizing while moving generally towards the west, the disturbance was designated as a tropical depression at 0000 UTC on July 5, and was further upgraded to a tropical storm by 1200 UTC later that day. Over the next few days, continued intensification occurred, and Bertha became a Category 1 hurricane on the Saffir Simpson hurricane scale, the first hurricane of the season, prior to moving through the northern Leeward Islands. Late on July 8, a period of rapid intensification began, and at 0600 UTC on July 9, Bertha reached its peak intensity with maximum sustained winds of with a minimum barometric pressure of Moving around the western periphery of the subtropical ridge, Bertha passed north of the Bahamas as a weakening hurricane before turning towards the north northeast and undergoing another period of rapid intensification. Late on July 12, Bertha made landfall between Wrightsville Beach and Topsail Beach, North Carolina with winds of Gradual weakening ensued the following day as Bertha moved up the Mid Atlantic and into New England before becoming an extratropical cyclone on July 14. The storm's remnants persisted for another several days, before dissipating on July 18. As Bertha passed through the northern Leeward Islands, it caused moderate to severe damage. In the United States Virgin Islands, heavy rainfall, hurricane force winds, and significant property damage was reported. In addition, many boats were destroyed, and total damage was estimated near $7.5 million (1996 USD). In Puerto Rico, effects from Bertha were very similar to those in the U. S. Virgin Islands. Heavy rainfall was recorded, peaking over half a foot in isolated areas. Despite this, reports of widespread inland flooding were scarce. Tropical storm force winds were observed, which is the cause of two indirect fatalities, when they died in a traffic accident. One death was directly attributed to Bertha when a tourist drowned in rough seas in Luquillo, Puerto Rico. Damage in Puerto Rico was also estimated to be near $7.5 million. The most devastating effects from the hurricane occurred in the United States, more specifically the state of North Carolina. Several fishing piers, marinas, and boats were destroyed as a result of Bertha's storm surge, and buildings across the eastern portion of the state were significantly damaged. Moderate rainfall spread across much of the Mid Atlantic and Northeast as Bertha moved towards the north, along with winds in excess of tropical storm force. In total, twelve fatalities were caused by Hurricane Bertha, primarily in Florida from rough seas.

On July 1, 1996, a tropical wave emerged off of the coast of Africa. On July 3, a weak low level circulation developed while located 500 mile (805 km) south of Cape Verde. The disturbance moved westward, and on July 5, it strengthened into a tropical depression in the central Atlantic. The depression tracked westward across the open waters of the Atlantic along the western periphery of a subtropical ridge. Later that day, the depression was upgraded to a tropical storm and was named Bertha. Over the next three days, Bertha tracked west northwest while gradual intensification was occurring. On July 7, Bertha was upgraded to a hurricane with sustained winds of while east of Guadeloupe. The next day, the center of circulation passed over Antigua as Bertha traversed the extreme northeastern portion of the Caribbean Sea causing moderate to minor damages. After that, Bertha passed rapidly in the southern portion of Sint Maarten. The storm gradually turned to the northwest on July 9 as maximum sustained winds reached while located 120 mile (193 km) northwest of Puerto Rico. Because the highest winds were located on the northeastern portion of the circulation, Puerto Rico received only tropical storm force winds near 50 mph. Forward speed slowed to as Bertha passed within 60 mile (97 km) of the Turks and Caicos, just before reaching its peak intensity. Damages from the storm were estimated at $7.5 million. The Bahamas and the north coast of the Dominican Republic likely suffered light damage, though no damage figures are available for either.

In Florida, a man was caught in rip currents offshore Jacksonville Beach and drowned. Farther south, swells also lashed the coasts of Broward, Miami Dade, and Palm Beach Counties. Throughout the area, beach patrols and lifeguards made dozens of rescues. Two other people drowned from rip currents in separate incidents at an unguarded section of Miami Beach. An additional fatality occurred in the state after a military jet evacuating the storm crashed into a house. Tides in Washington, D. C. increased to above normal, causing minor flooding at Hains Point and the Waterfront. Overflowing streams inundated several streets in Abbot. Two bridges were damaged in Anson. Many roads in the Camden area were washed out. Two people were injured when the car they were riding in struck a boulder, which had fallen onto the roadway because of the heavy rains. In the Castine area, streams that overflowed their banks flooded roadways. Minor flooding occurred along the Kennebec River in Kennebec County.
