In Costa Rica, the onset of the rainy season brings not just refreshing showers but also a dramatic increase in lightning strikes, creating hazardous conditions particularly for those outdoors. The recent experiences of three agricultural workers who survived a lightning strike in Río Jiménez, Guácimo, underscore the dangers posed by these powerful natural phenomena. This event marks a critical time to understand and prepare for the challenges of the season.
The Harsh Reality of Lightning Strikes
Surge in Lightning Activity
According to Ileana Mora from the Atmospheric Discharge Department of the Costa Rican Electricity Institute (ICE), May typically sees around 89,000 lightning strikes, with 2024 already recording 63,806 strikes by mid-May. This alarming number illustrates the significant increase in electrical activity during the rainy season. The most intense day so far was May 11, witnessing over 10,000 lightning strikes, underscoring the need for heightened caution.
A Close Call
The severity of the risk was highlighted this past Monday when Pedro Rodríguez Bolaños, a 29-year-old worker at a pineapple farm in Río Jiménez, sustained severe burns from a lightning strike’s shockwave. The incident occurred under cloudy skies, which facilitated the lightning strike that injured him and slightly affected two nearby colleagues. Rodríguez was urgently transported to the Hospital de Guápiles in serious condition, reflecting the grim potential outcomes of such events.
Safety First: Prevention and Protection
High-Risk Areas
The provinces of Puntarenas, Alajuela, Heredia, and parts of Guanacaste are identified as the regions most prone to lightning strikes in Costa Rica. However, the risk is nationwide, making it imperative for all residents and visitors to adopt precautionary measures during the rainy season.
Survival Tips
During thunderstorms, it is advisable to stay indoors, close all doors and windows, avoid using electrical appliances, and refrain from bathing to prevent electrical injuries. Contrary to common belief, seeking shelter under a tree is dangerous as lightning tends to strike taller objects, creating a hazardous radius around them.
For those caught outdoors, staying in a vehicle can offer some protection, as the tires may act as electrical insulators. However, this should not replace seeking a secure indoor shelter if possible.
Technological Aids and Community Awareness
Monitoring and Forecasting
ICE offers services that allow for the monitoring of storm approaches and atmospheric instability, which can be particularly valuable for those involved in outdoor activities, construction, and other high-risk occupations.
Meteorological Updates
The National Meteorological Institute (IMN) continues to forecast electrical storms throughout the week, with heavy rains expected especially in the afternoons. A convergence zone close to the country is enhancing the instability, contributing to the wet conditions. Local heating in the mornings and moisture from the Pacific Ocean are additional factors that sustain the unsettled weather.
Regional Variations
While most of the country has entered the rainy season, areas like Guatuso, Upala, and Los Chiles are still transitioning. Precipitation levels are expected to vary, with the Pacific and northern zones receiving between 40 to 80 mm, while the Central Valley and the Caribbean mountains may see slightly less intense but still significant rainfall.
A Call for Caution and Preparedness
The rainy season in Costa Rica is a time of beauty and increased greenery, but it also poses significant risks due to the high incidence of lightning strikes. The survival of the workers in Río Jiménez serves as a stark reminder of the dangers. It is crucial for everyone to stay informed, prepare adequately, and prioritize safety to navigate this season effectively.
