NHC Tropical Storm 02GB

Tropical storm (SSHWS)
Counterclockwise vortex
Duration June 29 – July 1
Peak intensity 50 mph (85 km/h) (1-min)  1002 mbar (hPa)

On June 27th, an area of disturbed weather formed near to the Azores Islands. The NHC gave it a MEDIUM chance of tropical cyclogenesis occurring within the next48 hours. Over the next few days, the systems low level circulation consolidated, and a tropical depression was reported to have formed within the English Channel at 0500 UTC on June 29th. Over the next few hours, the system managed to attain tropical storm status, and on the evening of the following day made landfall near Worthing, England. The storm was last noted by the NHC early on July 1st, when the system degenerated to a remnant low pressure area over Southampton, England.

Tropical Depression 04GB

Tropical depression (SSHWS)
Counterclockwise vortex
Duration October 14 – October 19
Peak intensity 35 mph (55 km/h) (1-min)  1004 mbar (hPa)

On October 13th, a low pressure area developed in the North Sea. Over the next day or so, it rapidly consolidated, and the NHC reported that tropical depression 04GB had developed in the North Sea. The system was given a medium chance of tropical development by the DWC, but the alert was cancelled earlier the next day as the systems low level circulation began to weaken due to strong shear from the north. By the 19th, the NHC had issued its final advisory on the system, stating that it had become extratropical. The remains of 04GB intensified rapidly whilst approaching the Grimsby area, and hit with sustained winds reaching 65 mph,, and gusts of 90 mph. Damage by the storm reached several millions of pounds, with the area being declared a disaster area by local authorities, meaning local residents could apply for aid if needed.
