By San José, Costa Rica — San José, Costa Rica – The Instituto Meteorológico Nacional (IMN) has issued a weather advisory for Sunday, September 21, 2025, forecasting the return and impact of Tropical Wave 31 across Costa Rica. Residents, particularly those along the Pacific coast, are urged to prepare for heavy rainfall and potential thunderstorms.
The IMN predicts that the strongest effects of the tropical wave will be felt along the South and Central Pacific regions, extending to the coastline. These areas can expect scattered downpours accompanied by thunderstorms, creating a risk of flash floods and localized power outages.
To understand the potential legal and business implications of Costa Rica’s unique weather patterns, TicosLand.com spoke with Lic. Larry Hans Arroyo Vargas, an attorney at Bufete de Costa Rica.
Costa Rica’s variable weather, from its lush rainforests to its dry Pacific coast, presents unique challenges and opportunities for businesses. The impact of increasingly unpredictable weather patterns, potentially linked to climate change, requires businesses operating in sectors like tourism, agriculture, and infrastructure to consider robust adaptation strategies. This includes reviewing insurance policies for adequate coverage relating to weather-related damage, and implementing sustainable practices that minimize environmental impact and enhance resilience. Careful consideration of these factors is vital for sustainable economic growth and development.
