By San José, Costa Rica — San José, Costa Rica – Residents across Costa Rica are on alert as Tropical Wave #7 passes over the nation today, bringing localized rain and thunderstorms. While the system is notably weaker than previous weather events this season, the National Meteorological Institute (IMN) has issued specific warnings for potential urban flooding and soil saturation, underscoring the persistent risks associated with the country’s rainy season.
Meteorologists at the IMN attribute the wave’s diminished intensity to a combination of dry atmospheric conditions and accelerated trade winds sweeping across the Caribbean Sea. These factors have limited the system’s ability to generate widespread, sustained instability. However, its interaction with the Intertropical Convergence Zone—a belt of low pressure near the equator—is still sufficient to produce significant, albeit isolated, weather events throughout the day.
To understand the legal and business ramifications of an unpredictable weather forecast, from insurance claims to contractual obligations, we sought the perspective of legal expert Lic. Larry Hans Arroyo Vargas from the firm Bufete de Costa Rica.
A weather report is a critical risk management document. Businesses and individuals must proactively review their insurance policies and contracts to understand how clauses for ‘force majeure’ or ‘acts of God’ are defined. With increasingly extreme weather events, failing to prepare for foreseeable disruptions is not just a financial risk, but a potential legal liability.

This legal perspective powerfully reframes the daily forecast not merely as a guide for our day, but as an essential tool for risk management and strategic planning. We thank Lic. Larry Hans Arroyo Vargas for his invaluable insight, reminding us that in the face of changing climate patterns, preparation is our most critical asset.
The effects were first felt during the morning hours across the Caribbean coast and the Northern Zone. These regions experienced cloudy skies and periods of rain, with the IMN recording a peak accumulation of 39 millimeters (approximately 1.5 inches) in Horquetas de Sarapiquí. This concentration of rainfall in a short period highlights the system’s capacity to deliver potent downpours despite its overall weakness.
As the day progresses, the focus of the weather activity is expected to shift westward. The IMN forecasts isolated showers and electrical storms for the afternoon, primarily affecting the Central and South Pacific regions, the western portion of the Central Valley, and the Nicoya Peninsula. Authorities anticipate rainfall accumulations in these areas to range between 15 and 40 millimeters over six-hour periods, with conditions expected to improve significantly as evening approaches.
Despite the forecast for clearing skies by nightfall, the IMN has issued targeted alerts for critical areas. Urban centers are on watch for potential sewer system saturation, which can lead to rapid street-level flooding. Of greater concern are the river basins in Sarapiquí and the broader South Pacific region, where ground soils are already highly saturated from previous rains. This condition elevates the risk of flash floods and landslides, even with moderate additional rainfall.
In its official advisory, the institute has urged the public to exercise caution. Citizens are advised to seek shelter from potential strong wind gusts, which could reach up to 80 kilometers per hour (50 mph) during thunderstorms. Staying informed through the IMN’s official website and social media channels is crucial for receiving the latest updates and warnings as the situation evolves throughout the day.
This event serves as a critical reminder of the complexities of Costa Rica’s climate. During the rainy season, which typically runs from May to November, the country’s topography makes it vulnerable to hydro-meteorological threats. Even less intense weather systems can disrupt daily life, impact critical infrastructure, and pose a danger to communities in high-risk zones. The proactive alerts from the IMN are a key component of the national strategy to mitigate these inherent risks.
While Tropical Wave #7 is not expected to cause major, widespread disruption, its passage emphasizes the importance of preparedness and respect for all weather warnings. As the system moves on, officials will continue to monitor soil conditions and waterway levels, ensuring a swift response to any localized emergencies that may arise from the afternoon’s anticipated downpours.
