Hurricane Andrew — a small and ferocious Cape Verde hurricane that brought unprecedented economic devastation along a path through the northwestern Bahamas, the southern Florida peninsula, and south-central Louisiana — was followed by Bonnie. Next came Charley, which was first detected on Meteosat imagery about 1000 km south of the Azores on 20 September.

The system, at that time a mid- to upper-level cyclonic circulation, became a tropical depression on 21 September, 1000 km southwest of the Azores, with an initial movement towards the northwest.

It took two more days before an eye appeared in the satellite images, and Charley became a hurricane. Analysis of satellite imagery suggests that the maximum sustained winds were 95 knots (175 km/h) and minimum central pressure was 965 hPa near 18:00 UTC on 24 September.

On 26 September, Charley began moving east-northeast with increasing speed over progressively cooler water. On 27 September Charley was downgraded to a tropical storm. It passed over the island of Terceira (Azores) where winds of 46 knots (85 km/h) and gusts up to 71 knots (131 km/h) were reported.

Finally, at 18:00 UTC on 27 September,Charley became an extratropical cyclone. Acceleration towards the northeast continued, until the system was absorbed by a larger extratropical low pressure system centered to the northwest of the British Isles.

The track of Charley is shown in the figure below.

The moment Charley was absorbed into the large extratropical cyclone is shown in the above visible image. Compared to the large cyclone southwest of Iceland, Charley appears rather small but with a well-defined spiral structure inserted into the original frontal system of the larger low pressure system.

Convection in the centre of Charley is still quite strong as shown by the shadows of the overshooting tops on the surrounding clouds.>
