Subsequent interactions with South America and an upper-level trough inhibited improvement of the system. The wave continued westward across the Atlantic and entered the Caribbean on August 16. Development was no longer expected over the following days as dry air created a hostile area for storm organization. Interaction with a monsoon trough reinvigorated shower and thunderstorm activity on August 11 across a large area southwest of the Cape Verde Islands, but the surface low had dissipated by this time. Embedded within an elongated trough, the weak system struggled to organize and convection soon diminished. A broad area of low pressure subsequently formed within the wave about halfway between Africa and the Cape Verde Islands. Accompanied by disorganized convective activity, development, if any, was expected to be slow. On August 10, the National Hurricane Center (NHC) began monitoring a westward moving tropical wave emerging off the west coast of Africa, centered along 16°W. Įxtratropical cyclone / Remnant low / Tropical disturbance / Monsoon depression Hundreds of ocean rescues, including over 100 in Malibu alone, were attributed to the storm, and overall losses reached $20 million. One person drowned in the surf near Malibu. A breakwater near Long Beach sustained $10 million worth of damage, with portions gouged out. Swells of 10 to 15 ft (3.0 to 4.6 m) battered coastal areas, with structural damage occurring on Santa Catalina Island and in the Greater Los Angeles Area. Toward the end of August, Marie brought one of the largest hurricane-related surf events to southern California in decades. Similar effects were felt across Baja California Sur. In Colima and Oaxaca, heavy rains from outer bands caused flooding, resulting in two fatalities. Off the coast of Los Cabos, three people drowned after their boat capsized in rough seas. The remnant cyclone eventually lost a well defined center and dissipated on September 2 about 1,200 mi (1,950 km) northeast of Hawaii.Īlthough Marie's center remained well away from land throughout its entire existence, its large size brought increased surf to areas from Southwestern Mexico northward to southern California. The large system gradually wound down over the following several days, with winds subsiding below gale-force on August 30. On August 29, after having lost all signs of organized deep convection, Marie degenerated into a remnant low. Over the next several days, Marie progressively degraded to below hurricane strength as it moved into an increasingly hostile environment with cooler waters and a more stable atmosphere. Marie subsequently underwent an eyewall replacement cycle on August 25 which prompted steady weakening. At its peak, the hurricane's gale-force winds spanned an area 575 mi (925 km) across. On August 24, Marie developed an eye and rapidly intensified to a Category 5 hurricane with winds of 160 mph (260 km/h). However, due to some vertical wind shear its intensification rate stalled, and for a time it remained a Category 1 hurricane on the Saffir–Simpson hurricane wind scale. Development was initially fast-paced, as the depression acquired tropical storm-force winds within six hours of formation and hurricane-force by August 23. With favorable atmospheric conditions, convective activity and banding features increased around the system and by August 22, the system acquired enough organization to be classified as Tropical Depression Thirteen-E while situated about 370 mi (595 km) south-southeast of Acapulco, Mexico. On August 19, an area of low pressure consolidated within the wave west of Central America.
The wave tracked westward across the Atlantic and Caribbean for several days. Some organization of shower and thunderstorm activity initially took place, but dry air soon impinged upon the system and imparted weakening.
The fourteenth named storm, ninth hurricane, and sixth major hurricane of the season, Marie began as a tropical wave that emerged off the west coast of Africa over the Atlantic Ocean on August 10. Hurricane Marie is tied as the seventh-most intense Pacific hurricane on record, attaining a barometric pressure of 918 mbar (hPa 27.11 inHg) in August 2014.
