On 19 November, a broad area of eastward-moving low pressure formed in the central Atlantic Ocean about 2,200 km (1,400 miles) southwest of the Azores.

[1] On 22 November, the non-tropical low pressure system began to gain some tropical characteristics, and its northward motion slowed to a stop.

[5] Delta's motion stalled as it reached the southern base of a large cyclonic trough over the northern Atlantic within which it was embedded.

[5] Maintaining its intensity, Delta remained motionless for half a day[6] until, that evening when it began a slow southward drift at 9.7 km/h (6 mph).

[7] Maintaining its intensity, Delta remained motionless for half a day[7] Convection broke down in the storm's western semicircle early on 25 November; the decreased organization caused slight weakening.

[5] Maintaining its intensity, Delta remained motionless for half a day[8] The southward motion slowed[9][10] and the weakening trend continued into the evening.

The extratropical storm, which maintained winds of near-hurricane strength, passed about 169 km (105 mi) north of the islands that night.

The storm moved over Morocco early on 29 November and rapidly weakened overland, dissipating late that day over northwestern Algeria.

Passengers at Tenerife North Airport, who were stranded when their flights canceled, witnessed parts of the new international terminal's roof tear off in the wind.

[14] In La Palma a falling palm tree, trunk snapped by the wind, injured the leg of a German tourist.

[14] For over 24 hours roads were closed on the islands of El Hierro, Tenerife and La Palma: the first two due to landslides and the third by the collapse of an old house and a massive tree.

Upon hearing of the destruction of the natural monument one man, later found to be clinically insane, unsuccessfully tried to kill himself and then stabbed three members of his own family.

No damage was reported there and in fact the system was welcomed by farmers who needed the rain to complete the sowing of cereal crops.

In La Corujera in Santa Úrsula, these generators were poorly received and over 1,000 local residents claimed to be affected by the noise and pollution.

The political opposition Popular Party challenged that the impact of Tropical Storm Delta proved the need for the island to prepare an emergency plan to deal with natural and man-made disasters.
