Hurricane Mitch

Hurricane Mitch developed in the Caribbean Sea in October 1998 and became one of the strongest and deadliest Atlantic hurricanes ever recorded. Some of the details of the hurricane and its effects are summarised below.

The Tropical Cyclone
Most hurricanes which develop in the Atlantic Ocean originate from small disturbances in the weather over western Africa (known as tropical waves) which move westwards across the Atlantic Ocean. A tropical depression forms when the cloud mass associated with a tropical wave starts to grow and rotate in an anti-clockwise direction. Mitch followed this pattern - originating as a tropical wave and eventually forming into a tropical depression when in the southern Caribbean Sea just north of Colombia.

Here is the life cycle of Mitch:-
22 October: Tropical Depression `Thirteen' forms (winds less than 39 mph), but by the end of the day is upgraded to Tropical Storm Mitch (winds greater than 39 mph) and starts moving northwards.
24 October: Mitch is upgraded to a hurricane (winds greater than 74 mph).
25 October: Hurricane Mitch turns towards the west.
26 October: Winds near the centre of the hurricane peak at 180 mph.
27 October: Mitch starts to weaken, but turns southwards towards the northern coast of Honduras.
29 October: Mitch is downgraded to a tropical storm and makes landfall over Honduras.
31 October: Mitch is downgraded to a tropical depression whilst moving slowly south-westwards and still producing heavy rain.
01 November: Mitch dissipates as a depression over Guatemala.
03 November: The remnants of Mitch have moved northwards and reform as a tropical storm in the southern Gulf of Mexico.
05 November: Mitch makes landfall on the Gulf coast of southern Florida.
06 November: Mitch is declared `extra-tropical' as it heads north-eastwards across the Atlantic.

After becoming an `extra-tropical' storm Mitch raced across the Atlantic and developed into a vigorous depression bringing stormy conditions to the north and west of the UK.

The Records
Hurricane Mitch became the joint fourth strongest Atlantic hurricane on record. On 26 October 1998 a central pressure of 905 mb was measured along with wind speeds averaged over one minute of 155 knots (180 mph). Here are the previous records:-

GILBERT (1988) 888 mb
UNNAMED (1935) 892 mb
ALLEN (1980) 899 mb
CAMILLE (1969) 905 mb

It must be noted that these records are for the Atlantic and Caribbean only. Many more hurricanes and typhoons of this strength have formed in the Pacific Ocean over the years.

Whilst Mitch was one of the strongest Atlantic hurricanes on record, the winds abated considerably as the storm moved inland. It was actually the huge amount of rainfall deposited by such a slow moving storm which caused most of the damage. Most rainfall recording instruments would have been destroyed during the storm. However, some records which survived indicated rainfall totals in Southern Honduras of 25" in 36 hours and 10" in 6 hours between 29 and 31 October*.

The Cost
The human cost of Hurricane Mitch was enormous. It will probably never be known exactly how many died. As of 19 November 1998* estimates were as follows:-

Honduras: 7000 dead, 8300 missing
Nicaragua: 3000 dead, 2200 missing
Guatemala: 258 dead, 121 missing
El Salvador: 272 dead, 100 missing

The economic cost of the hurricane is also huge and will probably be unquantifiable. However, with the change in landscape, destruction of homes, towns, villages and crops it is estimated that it could take decades for the economy to recover in the areas affected.

HONDURAS
The entire country was affected by Hurricane Mitch. Early estimates said 6,500 people had died with up to 11,000 missing. Up to 1.5 million people were displaced and made homeless. There were critical food, medicine, and water shortages. Hunger and near-starvation were widespread in many villages. Epidemics became a danger as malaria, dengue, and cholera made an appearance. Fever and respiratory illnesses were widespread amongst the survivors. Helicopters were required to take supplies to areas cut off by floods, but were in short supply. At least 20% of the country's population became homeless. Many of the unidentified dead were buried in mass graves or their bodies were cremated.

The infrastructure of Honduras was devastated. Whole villages were washed away and an estimated 70-80% of transportation infrastructure was destroyed. The majority of the country's bridges and secondary roads were washed away. Even airports were under water. Helicopters were required for most rescues and aid because of transportation difficulties. Fuel, electricity and running water became scarce commodities. Damage was so severe that it was calculated that it could take 15-20 years or more to rebuild the country. One third of all buildings in the capital were damaged by the floods. In outlying areas, over 25 small villages in the northern part of the country were swept away. Survivors were still clinging to roof tops a week or more after the storm. Heavy damage was caused along the coastline and off-shore islands from the storm surge and hurricane-force winds. Severe damage was inflicted on tourist resorts. Estimated damage was $4 billion in Honduras alone.

At least 70% of crops were destroyed, including 80% of the banana crop. Crop losses were estimated at $900 million. Large warehouses and storage rooms for coffee were flooded. Maize and corn crops were devastated. The damage by Hurricane Mitch to Honduran agricultural production will take years for recovery.

NICARAGUA:
Northwest and northern parts of the country were most affected. An estimated 3800 died with perhaps as many as 7,000 others still missing. Two million people were directly affected and 500,000 - 800,000 were made homeless. Intense near-stationary rain bands over western Nicaragua on Thursday and Friday (October 29-30) caused tens of inches of rain to fall. The crater lake atop the dormant Casita volcano filled and part of the walls collapsed on Friday, October 30, causing mud flows that eventually covered an area ten miles long and five miles wide. At least four villages were totally buried in the mud that was several feet deep. Over 2,000 of the dead were from the areas around the collapsed volcano near Posoltega. In many cases, survivors had to wait days before the mud had dried enough to walk to rescuers. Damage was extensive from flooding in other parts of the country, also. As late as November 8, over a thousand people were in urgent need of supplies on the Coco River near the border with Honduras. On November 5th, 500 bodies were found in the Coco River near the town of Wiwili. An additional 500 unidentified bodies had washed up on the Pacific shore after flood waters had washed their bodies out to sea. As with Honduras, there were critical food and water shortages in flooded areas. The infrastructure in affected regions was devastated. Several villages were buried under mud slides near the Casita Volcano. Damage estimates for Nicaragua are at $1 billion. Over 30% of the coffee crop was destroyed and there was serious damage to the bean, sugar, and banana crops.

EL SALVADOR
The western part of the country was most affected by rain bands spiralling into Mitch from the Pacific Ocean. 230 people died and 500,000 were forced from their homes by the flooding. As much as 80% of the maize crop was lost. Coffee plantations and the sugar cane crop was severely affected.

GUATEMALA
Over 200 people were killed by the floods. Ten U.S. citizens and one other person was killed in a plane crash supplying humanitarian aid on November 1. Nearly 80,000 people were evacuated from their homes because of the flooding. There was extensive damage to the coffee and banana plantations.

Foreign Aid Provided
Former Presidents George W. Bush and Jimmy Carter visited the region and called for re-structuring and scaling back of international debt owed by Honduras and Nicaragua. The United States gave $80 million in aid for Central America. Spain provided $105 million in aid and Sweden promised $100 -$200 million over a three year period. In addition, tons of food and grain were flown in by humanitarian organizations. Mexico provided an airlift of urgently needed supplies, and European countries donated $8 million. Canada supplied over $7 million in assistance. Additional help came from Japan and other countries.
