1988 Atlantic hurricane season

From Academic Kids

The 1988 Atlantic hurricane season was an ongoing event in the annual cycle of tropical cyclone formation. It officially started June 1, 1988, and lasted until November 30, 1988.

The most notable storms of the season were Hurricane Gilbert and Hurricane Joan.

Hurricane Gilbert caused widespread serious damage across the Caribbean and into Central America. Gilbert killed 318 people, most in Mexico, and was the first hurricane to make landfall in Jamaica since 1951.

Hurricane Joan was a very unusual storm. It formed east of the Windward Islands, and then hugged the northern coast of South America for several days, only the second storm known to have taken that track. It reached hurricane strength while off the coast of Colombia, and made landfall at Bluefields, Nicaragua. Joan killed 148 in Nicaragua, with the large death toll is in part blamed on residents' resistance to evacuation. Joan strengthened rapidly in the day before landfall, and was a Category 4 storm when it crossed the coastline.

Another 68 were killed in other affected nations. Damage in Nicaragua was estimated at 840 million USD (1988 dollars). Damage estimates outside Nicaragua are not available, but are likely to be many hundreds of millions of dollars.

After passing over Nicaragua and into the Pacific Ocean, Joan was renamed Hurricane Miriam. Greatly weakened, Miriam managed to maintain minimal strength for almost two weeks, but eventually dissipated. Joan/Miriam is one of only seven storms on record as having made the transition from an Atlantic to a Pacific hurricane.

Storms

Tropical Storm Alberto

A Tropical Depression formed off South Carolina on August 5 and followed the East Coast of the United States northwards. It became a tropical storm on August 7 and crossed the Canadian Maritimes before becoming extratropical near Newfoundland. There was no significant damage.

Tropical Storm Beryl

A tropical depression developed over Louisiana on August 7. It drifted south and strengthened to Tropical Storm Beryl before retuning over New Orleans and heading inland. One death at sea was attributed to Beryl, and damage to coastal areas was estimated at $4 million.

Tropical Storm Chris

A Tropical Depression formed in mid-Atlantic on August 21, passed though the Lesser Antilles, across Hispaniola and through the Bahamas before becoming Tropical Storm Chris east of Florida on August 28. It made landfall near Savannah, Georgia and moved up the Eastern Seaboard as a tropical depression, merging with a frontal system on August 30. 3 deaths occurred in Puerto Rico and one in South Carolina, damage was minor.

Hurricane Debby

A detached portion of the same tropical wave that spawned Chris formed a second tropical depression west of Yucatan on August 31. Moving westward it became a tropical storm, and was measured at hurricane strength just before landfall at Tuxpan, Mexico. The centre made the transition to a Pacific cyclone as Tropical Depression Seventeen-E. It is believed to have been a hurricane for about 6 hours.

10 deaths were reported from Mexico, mostly caused by mudslides.

Tropical Storm Ernesto

Ernesto formed east of Bermuda on September 3 and moved rapidly east across the Atlantic. It was absorbed by an extratropical low north of the Azores. There were no reports of damage or casualties.

Hurricane Florence

Florence formed in the western Gulf of Mexico on September 7, and after a couple of days of rather aimless motion accelerated rapidly northwards. It became a hurricane about 12 hours before crossing the Mississippi Delta and passing over New Orleans and Lake Pontchartrain. The dwindling storm was tracked as far as north-east Texas.

Damage in Louisiana was estimated at $2.5 million, with a further $300,000 due to flooding in the Florida Panhandle. One storm-related death was reported.

Unnamed storm (TD 13)

Tropical Depression 13 formed north-east of Cape Verde on September 7. It headed north-northwest and faded out west of the Western Sahara region on September 10. Ship and satellite observations indicate it reached storm strength for about 48 hours, but in view of its extreme eastern track it was not assigned a name at the time. Moderate to heavy rain was reported from the west coast of Africa, no damage was reported.

Hurricane Gilbert

Hurricane Gilbert caused widespread serious damage across the Caribbean and into Central America. Gilbert killed 318 people, most in Mexico, and was the first hurricane to make landfall in Jamaica since 1951.

Hurricane Helene

Helene formed west of Cape Verde on September 17 and swung to the north in the central Atlantic. It strengthened to Category 4 by September 23 before weakening over cooler water, eventually becoming extratropical on September 30. It never approached land and no damage or casualties were reported.

Tropical Storm Isaac

Tropical Storm Isaac was a short lived system, being named on September 30 east of the Lesser Antilles but maintaining storm strength for only 18 hours. The circulation faded away soon after. There were no reports of damage or casualties.

Hurricane Joan

Hurricane Joan killed 148 people in Nicaragua alone, and another 68 people in other affected nations.

Tropical Storm Keith

The last storm of the season became a Tropical Depression south of Haiti on November 17 and reached storm strength on November 20. It curved round to clip the tip of the Yucatan peninsula, then crossed Florida from Sarasota to Melbourne on November 23. It became an intense extratropical system over the Atlantic.

Damage from storm-surges in Florida was put at $3 million. Flooding in western Cuba caused considerable damage to crops. No fatalities were recorded.
