Meteorological History
A tropical wave moved off the coast of Africa between August 15 to August 16. The wave moved westward at 15 to 20 mph (24 to 32 km/h), and developed convection along the wave axis. It slowly organized, developing a low-level circulation, and formed into a tropical depression on August 20 while located about 775 miles (1,250 km) east of Barbados. A reconnaissance aircraft flight into the system on August 21 confirmed the existence of a depression, which reported winds of only 23 mph (37 km/h) with a pressure of 1,012 mbar. The depression slowly strengthened and organized, and after turning to the west-northwest it intensified into Tropical Storm Emmy on August 22 while located 370 miles (600 km) east-northeast of Guadeloupe. The tropical wave from which Emmy developed from continued westward through the Caribbean Sea and ultimately developed into Tropical Storm Joanna in the eastern Pacific Ocean.
Tropical Storm Emmy turned more to the northwest, and passed about 135 miles (220 km) northeast of Barbuda on August 23. The rapid development of an unseasonable frontal low pressure system to the northeast of the storm turned Emmy sharply east-northeastward on August 25. Its eastward movement at such a low latitude for the time of year was unprecedented. The storm steadily intensified and Emmy attained hurricane status later on the 25th while located 270 miles (430 km) north of Barbuda. After moving eastward for about 24 hours, the Westerlies retreated northward, and Emmy turned gradually to the northwest.
A strong ridge over the north Atlantic Ocean turned Emmy sharply eastward on August 29. The hurricane continued to strengthen, and Emmy attained a peak intensity of 105 mph (170 km/h) shortly after turning to the east while located 500 miles (800 km) northeast of Bermuda. The hurricane maintained its peak intensity for 42 hours while moving eastward at 17 mph (27 km/h), and slowly weakened after peaking in strength. On September 1, Emmy turned to the east-southeast, and a day later it turned to the northeast as its forward motion decreased. Emmy passed through the Azores on September 3, and the following day it became extratropical to the north of the islands. The extratropical remnant persisted another six hours before being absorbed by approaching Hurricane Frances.

“The history of American politics is littered with bodies of people who took so pure a position that they had no clout at all.”
