Diagnosis: This Tuesday morning, tropical cyclone Ian has intensified to a category 3 hurricane, and is passing through western Cuba about to leave the Caribbean Sea. This system maintained its indirect influence on the national territory even this morning in the country, favoring a flow of winds from the west on the Pacific slope and causing scattered rains of variable intensity in Orotina, Puerto Cortez and the Nicoya Peninsula in coastal sectors, the accumulated were less than 25 mm.

Forecast: For the afternoon and early hours of the night it will remain partially cloudy to cloudy over the national territory with variable rainy activity, characteristic of the rainy season. In the North Zone and Caribbean mountains, downpours with a localized strong storm are anticipated, estimated amounts between 20-60 mm with amounts greater than 70 mm in a timely manner. For the Central Valley and the Pacific slope, isolated rains with localized downpours are anticipated, estimated amounts between 20-30 mm with possible amounts greater than 50 mm in a timely manner.

Warning: Caution in the regions of the Pacific slope and mountainous sectors of both the Central Valley and the North Zone and the Caribbean, in addition to the Nicoya Peninsula and the central zone of Guanacaste, since these regions present high levels of saturation.

Due to the above, the IMN recommends: • Caution due to saturation of the sewage system and possible sudden floods, as well as the main routes of the country in case of heavy rain events. • Prevention before an electrical storm and seek refuge in a safe place in the event of strong gusts of wind appearing or being perceived near storm clouds, due to the possible fall of tree branches, power lines, among others. • Be alert in areas that are prone to landslides in the mountainous sectors of the Central Valley. • Stay informed through social networks, Twitter: @IMNCR, Facebook: National Meteorological Institute CR and the WEB Page:
