The storm delivered enormous rainfall totals that inundated communities, disrupted transportation, and damaged infrastructure.
The total damage in El Salvador and neighboring countries was estimated at around $1.1 billion. Agatha remains one of the deadliest storms to have affected the eastern Pacific region since Hurricane Pauline in 1997.
Residents were caught off guard by the intensity and speed of the storm, which developed and made landfall within a short period.
Emergency responses were overwhelmed by the widespread devastation.
6. Hurricane Joan (1988)
Hurricane Joan, a powerful tropical cyclone, caused havoc in Central America in October 1988. Originating in the Caribbean, Joan made its way westward for nearly two weeks. It brought severe flooding and destruction, impacting over a dozen countries.
When Joan crossed into the Pacific, it was renamed Hurricane Miriam. It continued to affect the region with torrential rains and strong winds. El Salvador and southern Guatemala experienced considerable rainfall during this period.
Hurricane Joan led to more than 200 fatalities and widespread damage.
The hurricane’s impact was notably severe due to prolonged heavy rains, which caused major flooding and displacement of communities.
7. Hurricane Stan (2005)
Hurricane Stan struck in early October 2005. It started as a tropical storm but quickly intensified, becoming a hurricane on October 4. The storm had a significant impact on Central America and Mexico, particularly affecting El Salvador.
Stan caused severe flooding and landslides in El Salvador. The flooding led to widespread damage in several communities. Many people lost their homes and livelihoods.
The death toll was high, with reports of at least 2,000 deaths linked to the storm and its aftermath. Not all these deaths were directly due to the hurricane itself.
One of the areas severely hit by the storm was the region surrounding the Ilamatepec volcano. The volcano erupted just days before the hurricane, compounding the disaster with volcanic ash and pyroclastic flows.
8. Tropical Storm Selma (2017)
Tropical Storm Selma made history by being the first named storm to make landfall in El Salvador. Selma formed south of Central America and moved north, making landfall near Playa El Pimental on October 28, 2017.
The storm caused heavy rainfall leading to flash-flooding and mudslides, resulting in significant damage in El Salvador. This was notable due to its rare location of formation and impact.
Selma was short-lived but had a considerable effect on the region. While it didn’t reach hurricane strength, its impact was significant, especially in terms of rainfall and flooding.
9. Hurricane Cesar (1996)
Hurricane Cesar was a notable storm in 1996. It began as a tropical system in the southern Caribbean Sea before affecting parts of South America and Central America.
Cesar became a hurricane with impressive wind speeds. As it crossed the Atlantic to the Pacific, it was particularly notable for being one of the few storms to retain intensity through the crossover.
When Hurricane Cesar struck El Salvador, it brought heavy rain and strong winds.
These conditions led to flooding and landslides, causing significant damage to infrastructure and agriculture in the region.
10. Tropical Storm Ida (2009)
Tropical Storm Ida formed on November 4, 2009, in the southwestern Caribbean Sea. Initially a tropical depression, it intensified and made landfall in Nicaragua with winds of 80 mph. As it moved, it also affected Honduras and El Salvador.
In El Salvador, Ida did not cause significant damage. This was despite the storm’s powerful winds and heavy rains. Neighboring countries felt greater impacts, but El Salvador remained largely unaffected.
Ida traveled through the Yucatan Straits and into the Gulf of Mexico, increasing in strength. At one point, it achieved hurricane intensity. The storm eventually turned into a nor’easter, causing problems along the US Mid-Atlantic coast.
Understanding Storm Categories
Storms are classified based on their wind speeds and potential for damage. These classifications help communities prepare and respond effectively to severe weather events.
Classification of Storms
Storms are categorized using the Saffir-Simpson Scale, which measures wind speeds and estimates potential damage. This scale ranges from Category 1 to Category 5:
- Category 1: Wind speeds of 74-95 mph. Minimal damage.
- Category 2: Wind speeds of 96-110 mph. Moderate damage.
- Category 3: Wind speeds of 111-129 mph. Extensive damage.
- Category 4: Wind speeds of 130-156 mph. Severe damage.
- Category 5: Wind speeds over 157 mph. Catastrophic damage.
This classification system allows meteorologists to provide clear warnings to the public.
Impact on Communities
The impact of storms on communities can be devastating, especially in coastal regions.
Strong winds and heavy rains can lead to building damage, power outages, and flooding.
Communities might face disrupted transportation and communication systems.
Health services can be overwhelmed by the number of injuries and illnesses following a storm.
Recovery efforts often take months or even years, requiring significant resources and coordination.
Historical Records and Patterns
Historical records show that certain regions are more prone to severe storms.
El Salvador, for example, has faced numerous hurricanes and tropical storms over the years, with significant events like Tropical Storm Amanda and Hurricane Cesar-Douglas.
By studying these patterns, scientists can predict future storms and their potential paths.
This helps in preparing better disaster management plans and improving early warning systems.
Historical data also assists in understanding how climate change might be affecting storm frequency and intensity.
Meteorological Factors Behind Major Storms
Several key meteorological factors contribute to the formation and impact of major storms in El Salvador.
These include climatic influences, the effects of El Niño and La Niña, and seasonal variations in weather patterns.
Climate Influences on Storm Formation
El Salvador is located in a tropical climate zone, which plays a significant role in storm formation.
High sea surface temperatures provide the energy needed for storm development.
Warm, moist air rises from the ocean, creating low-pressure systems that can grow into tropical storms and hurricanes.
The Saffir-Simpson scale is often used to categorize these storms based on wind speed and potential damage.
El Niño and La Niña Effects
El Niño and La Niña are climate phenomena that significantly impact weather patterns in El Salvador.
During an El Niño event, warmer ocean temperatures can lead to increased evaporation and more intense storms.
Conversely, La Niña typically brings cooler ocean temperatures and can result in reduced storm activity.
These phenomena occur irregularly but have a profound impact when they do.
Seasonal Variations
Storm activity in El Salvador also varies by season.
The hurricane season generally runs from June to November. During this time, conditions are more favorable for storm development due to higher sea temperatures and increased atmospheric instability.
For example, recent storms like Tropical Storm Pilar occurred within this period, demonstrating the seasonal trend of storm activity.
