Aviso Meteorológico
Condiciones lluviosas vespertinas en el Pacífico y Valle Central
21 de mayo de 2021
10.00 a.m.
Diagnóstico: Durante esta tarde la cercanía de la Zona de Convergencia Intertropical las condiciones cálidas regionales favorecen a las actividades convectivas vespertinas.
Pronóstico: durante la tarde y primeras horas de la noche se espera actividad lluviosa, aislada pero intensa en la mayor parte del Valle Central, península de Nicoya, montañas del Pacífico Central y Sur.
Los montos de lluvia estarán entre 30-70 mm en el Pacífico Central y Sur, montos entre 10-45 mm en el Valle Central y montañas del Caribe, Zona Norte.
Advertencia: Especial atención en: Valle Central, el Pacífico Central y Sur por los eventos de lluvia que se puedan presentar, además de precaución por la actividad eléctrica.
Debido a lo anterior, el IMN recomienda:
- Precaución en zonas con vulnerabilidad a inundaciones por saturación de alcantarillado y/o desbordamiento de quebradas.
- Cautela ante tormenta eléctrica y buscar refugio en un sitio seguro en caso de presentarse o de percibir fuertes ráfagas de viento cerca de las nubes de tormenta, debido a la posible caída de ramas de árboles, tendido eléctrico entre otros.
- Prevención en zonas propensas a deslizamientos.
