Informative Weather Warning
Tropical Storm Bret dissipated this Saturday, but its remnants maintain a trajectory towards Central America
24 de junio de 2023
5:00 pm
According to the most recent report from the National Hurricane Center, Bret has dissipated, losing its characteristics of a tropical cyclone. The remnants of the system are positioned on the Caribbean Sea off the Colombian coast According to the most recent analyzes and numerical modeling, the remnants of Bret will have a zonal displacement through the Caribbean Sea, reaching northern Nicaragua at dawn on Monday, so that it will not have a direct impact on Costa Rica. However, the humidity that the system drags can reinforce the precipitations in the country for Monday. Due to the above, the IMN recommends: Pay attention to the issuance of informative weather warnings that are published in: Twitter: @IMNCR Facebook: National Meteorological Institute WEB page: www.imn.ac.cr This is the last report related to this event.
