North Atlantic Basin:
Hurricane Bob: Hurricane Bob approached the North Carolina coast late on
18 August with the center passing just east of Cape Hatteras just after 00
UTC 19 August. The storm reached a peak intensity of 100 kt and a central
pressure measured by aircraft of 950 mb. Bob accelerated north-northeast
and passed over the eastern part of New England on 19 August. The center
briefly came back out over the Gulf of Maine before making landfall on the
Maine coast. Bob became extratropical over New Brunswick, Canada on 20
August. Bob brought hurricane force wind gusts to southern and eastern
Rhode Island and southeastern Massachusetts including the offshore islands
of Block Island, Martha's Vineyard, and Nantucket. Damage and casualty
statistics are still incomplete. However, at least 12 people are known dead
so far.

on 24 August. Moving west-northwest, the depression crossed the southern
Cape Verde Islands the same day. As of this writing, intensity appears to
have peaked at 30 kt.
