WEEKLY TROPICAL CYCLONE SUMMARY #5: SEPTEMBER 1 - 8, 1991
North Atlantic Basin:
Hurricane Claudette: Tropical Depression Six formed near 27N 56W on 4
September. Moving west-southwestward, the depression became Tropical Storm
Claudette the next day. Rapid intensification then occurred, as Claudette
reached hurricane intensity on 6 September with winds reaching 100 kt later
that day. Winds peaked at 110 kt on 7 September as the hurricane moved
northwestward. It must be pointed out that the maximum intensity of the
storm occurred in a 20 hr gap in air reconnaissance, so the exact peak
intensity is still open to debate. At the end of the summary period,
Claudette was moving northward east of Bermuda with winds down to 90 kt.
Tropical Storm Danny: Tropical Depression Seven formed near 11N 26W on
7 September. Moving westward, its winds had reached 40 kt by the end of the
summary period.

on 8 September. At the end of the summary period, it was moving northwest
with 25 kt winds.
