Aviso Meteorológico Informativo
Se forma la Tormenta tropical Nana en el Caribe
1 de septiembre de 2020
10.30 am
Diagnóstico: La onda tropical #33 se ha fortalecido en la tormenta tropical Nana al sur de Jamaica según el Centro Nacional de Huracanes (NHC por sus siglas en inglés).
Pronóstico: Los últimos análisis indican que dicho disturbio se trasladará hacia el oeste sobre el golfo de Honduras, manteniéndose como tormenta tropical; se estima mayor cercanía a Costa Rica alrededor del miércoles 2 de septiembre, cuando se ubique sobre Honduras.
Debido a su posible posición y fortalecimiento, hay probabilidad de influencia indirecta generando un reforzamiento de la actividad lluviosa en el Pacífico, sin embargo, en los análisis actuales este reforzamiento será aislado y poco generalizado.
El IMN mantendrá estricto seguimiento de la evolución de dicho este sistema e informará oportunamente de cualquier variación del mismo y su posible influencia al país.
Por lo tanto, el IMN recomienda:
- Manténganse informados a través de las redes sociales, Twitter: @IMNCR, Facebook: Instituto Meteorológico Nacional CR y la Página WEB: www.imn.ac.cr
