Meteorological Analysis
|
Gert originated from a tropical wave which left the coast of Africa on September
10th. The wave organized relatively fast and became a tropical depression on
the 11th. The depression then continued WNW under the subtropical ridge and
became tropical storm Gert on the 12th. Gert continued to steadily intensify
and reached hurricane strength on the 13th. Gert then reached its max intensity
of 145 mph on the 16th and began to turn more northerly into a weakness in
the subtropical ridge by the 17th. As Gert was turning north, it scraped by
Bermuda on the 21st. Hurricane force winds briefly affected the island as well as
very heavy surf. Gert then began to weaken as shear increased from an
approaching trough. By the 23rd Gert was downgraded to a tropical storm. Gert
then became extratropical near Newfoundland and was absorbed by a larger
system on the 23rd. Gert brought stormy conditions ashore in Newfoundland
during this time.

Casualty and Damage Overview
|
2 deaths are attributed to Gert. Both of these deaths were caused by a rogue
wave in Maine that appeared to be in association with Gert's swells. Beach
erosion occurred on both Bermuda and Newfoundland from Gert, although
there is no official damage total.
