Tropical Storm Arthur was the first tropical cyclone of the 2002 Atlantic hurricane season . The storm's origins can be traced back to a dying cold front in the Gulf of Mexico , which dumped light to medium precipitation in the southeastern US states. After its development off the coast of North Carolina on July 14, Arthur moved rapidly northeast for the duration of its existence as a tropical system. It reached its greatest intensity with wind speeds of 95 km / h on July 16, when the influence of a subtropical storm and cooler water began to transform into an extra-tropical storm . The remains of Arthur moved over Newfoundland in a gusty wind and one person drowned there due to heavy rains.
Storm course
The origins of the system were believed to be a dying cold front in the northeastern Gulf of Mexico . On July 9, a weak near-surface circulation was observed, which was associated with an extensive depression. Although there was generally high surface air pressure in the region, the wind shear at altitude was conducive to slow cyclogenesis . The system moved slowly north-northwest and developed despite the limited and poorly developed thunderstorm activity.
Until July 11, dry air and adverse wind shear prevented convection from forming near the center of the storm. The low stretched, although on July 12 the convection became more centered as the system drifted in a northeasterly direction. An approaching mid-height trough forced the system to increase the speed of the train across the Florida Panhandle , with storm activity quickly subsiding. On July 13, meteorologists expected the system to be absorbed by the trough. However, the low pressure area reached the western Atlantic Ocean off North Carolina early on July 14th, and after that the convection improved, so that the system was better organized. Both circulation and convection became more noticeable, and the National Hurricane Center suggested that the system had evolved into Tropical Depression One, about 75 km west-southwest of Cape Hatteras .
After developing into a tropical cyclone, the system quickly moved in an east-northeast direction, thanks to a growing low pressure area south of the maritime provinces . Arthur maintained a good discharge at height and his trajectory across the Gulf Stream allowed for constant intensification. Early on July 15th the convection increased in the center and formed a rain band southwest of the center; as a result, the tropical low pressure area was upgraded to Tropical Storm Arthur. After Arthur continued to intensify, the storm reached its greatest strength in the early morning of July 16 about 790 km south-southeast of Halifax , Nova Scotia, with winds of 95 km / h. Until then, the convection over the center had been able to organize itself well, despite slight westerly wind shear . Subsequently, the center was separated from the area with the strongest convection and Arthur began transitioning into an extra-tropical cyclone when it was at its greatest intensity. The storm turned northwards around the larger low pressure area at medium altitude and on July 17 the storm completed the transition to an extra-tropical system. Shortly thereafter, the extratropical residual low crossed the east of Newfoundland . On July 19, the remains were caught in a south-easterly current between Newfoundland and Greenland, and in the late evening peak wind speeds dropped below gale force.
Effects
The previous tropical disturbance caused heavy rainfall in Florida , Georgia and South Carolina , with a maximum of 114 mm in Weston , Florida. The system brought widespread rainfall to North Carolina that totaled 25–75 mm. On July 16, Arthur passed north of Bermuda , where the rainfall was moderate due to the storm at 14.5 mm. As an extratropical storm, Arthur produced squalls and moderate precipitation in Newfoundland that were on the order of 25mm. One person drowned in the Conne River as a result of the storm .
Five ships reported winds of the strength of a tropical storm in connection with Arthur, two of them when it was already extra-tropical. In the early hours of July 16, a ship with the callsign Weston reported sustained winds of 80 km / h from a south-southwest direction, which was the strongest value reported by a ship. When the storm approached extra-tropical Canada, a measuring buoy reported eight-minute wind speeds of 70 km / h and gusts of 95 km / h.
Because the damage Arthur caused was minimal, the name was not removed from the list of tropical cyclone names by the World Meteorological Organization and was reused during the 2008 Atlantic hurricane season .
