|Hurricane Alberto in the Central Atlantic
A tropical wave moved off the coast of Africa on August 3. The wave was extremely well developed already, and it developed
even more immediately after moving over water, and became Tropical Depression Three on August 3. The depression continued
to become better organized as it moved to the WNW, becoming Tropical Storm Alberto on August 4. The strengthening continued
steadily and Alberto became a hurricane on August 6, and reached a first peak intensity of 90 mph winds on the 7th, as the
strengthening stopped. Vertical wind shear on Alberto increased steadily starting late on August 7, which weakened the storm
considerably, and Alberto was downgraded to a tropical storm on August 9. As it weakened, it turned to the northeast and accelerated
on August 10 and it regained hurricane strength that day.
An upper level low continued to turn the storm more to the north, and eventually to the northeast as Alberto became a
Category 3 storm on August 12, when about 300 miles east of Bermuda. A peak intensity of 130 mph winds was reached on that
day, with a pressure of 950 mbar. Alberto was a very impressive storm at this time, with a very large and clear eye, about
50 miles in diameter. More upper level shear resumed on August 13, and Alberto weakened accordingly and was downgraded to
a tropical storm on August 14. The swift movement to the east came to a halt on the 14th as the now Tropical Storm Alberto
slowed and began to embark on a very large clockwise loop. The storm began to restrengthen as it neared the end of the loop,
and regained hurricane status on August 18 for the third time.
Alberto reached Category 2 status on August 20, with winds of 105 mph. Alberto was beginning to accelerate to the northeast
at this time, and it began to weaken as it did so. Alberto was downgraded back to a Category 1 hurricane just as it completed
the loop on August 21. Alberto wakened to a tropical storm for the last time on August 22, just before becoming extratropical
the next day. The extratropical remnant continued to the north, and dissipated on August 25. Hurricane Alberto was the seventh
longest lasting hurricane in the Atlantic, lasting for a total of 23 days, and is the second longest lasting in the month
of August. Alberto holds the record for the most distance traveled by an Atlantic hurricane, as it traveled over 6,500 miles.
Despite its long and bending path, Alberto fortunately stayed out at sea and did not affect any land areas.
