Hurricane Joan was a long lived and powerful tropical cyclone that caused death and destruction in over a dozen countries in the Caribbean and Central America.
Widespread suffering and economic crises were exacerbated by Joan, primarily across Nicaragua, as heavy rains and high winds impacted those near the hurricane's path.
After crossing Central America into the Pacific, the cyclone was renamed Tropical Storm Miriam, with the system's dissipation occurring southwest of Mexico.
[4] It formed from an area of convection in the Intertropical Convergence Zone that moved off the coast of Africa early in October.
It then slowly executed a small counterclockwise loop, possibly in response to the nearby Tropical Depression Eighteen.
A strong anticyclone over the southwestern Caribbean Sea created an extremely favorable environment, and Joan underwent rapid deepening at a rate of 38 millibars in the space of a day.
[2] Tropical Storm Miriam hugged the coast of Central America and reached its peak of 986 millibars on October 24.
These warnings provided several hours' worth of lead time, allowing evacuations and preparations to be made.
[13] In addition, flash flood and mudslide warnings were issued for western Panama, Costa Rica, Honduras, and Nicaragua starting on October 21.
Tropical Storm warnings were issued for the Pacific coast of Nicaragua, El Salvador, and the Gulf of Fonseca on October 24.
In addition, new flash flood and mudslide warnings were raised for Guatemala and the Mexican state of Chiapas on October 24 and 25, respectively.
Increased moisture in Joan's wake caused persistent rainfall on the islands for several days, leading to widespread flooding.
[15] The national electric company had 620 miles (1,000 km) of downed power lines, at the cost of 2.5 million USD (1988 dollars).
[2] The hurricane caused severe disruption in most of Nicaragua's remaining rain forests in the areas it hit, and also stripped trees of leaves.
[23] In the southeast rain forests, Joan toppled or snapped 80 percent of the trees and completely destroyed 500,000 hectares (1,200,000 acres) of canopy.
[2] In an unfortunate coincidence, Hurricane Joan hit shortly after an armed conflict in the region had started to cool off.
Rainfall caused 20 rivers to burst their banks, flooding 75 settlements, including the city of Quepos, Costa Rica on the Pacific coast.
[28] In Mexico, heavy rainfall associated with Tropical Storm Miriam caused the cancellation of flights from the airport at Tuxtla Gutiérrez.
The Canadian, Swedish, West German, Spanish, and Dutch governments contributed aid amounting to 2 million dollars (1988) each.
[22] The slow response to requests for aid was contributed to by the Sandinista Government's actions, which was viewed by a few anonymous diplomats from other countries who commented to the press, as undermining the peace process championed by Óscar Arias.
[22] In addition, the government also barred foreign humanitarian groups from receiving American aid, as well as turning back a relief shipment days before the storm.
[22] On October 28, 1988, the United Nations General Assembly passed without a vote Resolution 17 of its 43rd session in response to the disaster.
[30] On account of the deaths and destruction caused by the hurricane in the Atlantic basin, the name Joan was retired by the World Meteorological Organization in the spring of 1989.
